Answer:
5) x = -1
6) x = 2
Step-by-step explanation:
5) 5 + 2x + 6 = x + 10
2x + 11 = x + 10
2x + 1 = x
1 = -x
-1 = x
6) (9x + 7) + (-3x + 20) = 39
6x + 27 = 39
6x = 12
x = 2
Answer:
For question 5, x= -1
Step-by-step explanation:
Segment Addition Postulate = ab+bc=ac
For Question 5,
(a) + (b) = (c)
5+2x + 6 = x+10
5+2x+6=x+10
To solve that,
5+2x+6=x+10
Add 5+6
11+2x=x+10
Subtract 11 from both sides
2x= x-1
x-1=2x

Answer:
x-int: (8/3, 0)
y-int: (0, -32/3)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
Step 1: Write equation
2x - 1/3 = 1/2y + 5
Step 2: Subtract 5 on both sides
2x - 16/3 = 1/2y
Step 3: Multiply 2 on both sides
4x - 32/3 = y
Step 4: Rewrite
y = 4x - 32/3
Step 5: Find x-int
0 = 4x - 32/3
32/3 = 4x
x = 8/3
(8/3, 0)
Step 6: Find y-int
y = 4(0) - 32/3
y = 0 - 32/3
y = -32/3
(0, -32/3)
Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 3x + 9 and TQ = 5x -5
PT=(Simplify your answer.)
Answer:
PT=30 units
Step-by-step explanation:
Given that:
Line PQ which has a mid point at T.
[tex]PT = 3x + 9[/tex] and
[tex]TQ = 5x -5[/tex]
To find:
PT = ? in simplified terms.
Solution:
First of all, let us recall that mid point on a line segment is a point that divides the line in two equal parts.
In other words:
If a point B is the mid point of line segment AC, then AB = BC.
Here, the point T is the midpoint of PQ.
i.e. PT = TQ
[tex]3x+9=5x-5\\\Rightarrow 3x-5x=-5-9\\\Rightarrow -2x=-14\\\Rightarrow x=7[/tex]
Putting value of [tex]x[/tex] in PT above:
[tex]PT = 3x+9 = 3 \times 7 +9 \\\Rightarrow \bold{PT=30\ units}[/tex]

Frank has completed 34 deliveries so far this week. He needs to make 85 deliveries for the week. What percentage of his deliveries has Frank completed?
Answer: 40 percentage of his deliveries has Frank completed
Step-by-step explanation:
Given : Deliveries completed by Frank = 34
Total deliveries = 85
Percentage of deliveries has Frank completed = [tex]\frac{\text {Deliveries completed by Frank}}{\text {Total deliveries}}\times 100[/tex]
Putting in the values:
Percentage of deliveries has Frank completed = [tex]\frac{34}{85}\times 100=40\%[/tex]
Thus 40 percentage of his deliveries has Frank completed

Answer:
So, the function is increasing over: [tex](4,\infty)[/tex]
And it's decreasing over: [tex](-\infty,4)[/tex]
Step-by-step explanation:
So first, let's graph the function. Please refer to the attached graph.
The function is increasing when the function is going upwards, and the function is decreasing when the function is going downwards.
From the graph, we can see that the function is going upwards after x=4. Therefore, the function is increasing for all values to the right of 4. In interval notation, this is:
[tex](4,\infty)[/tex]
Also, we can see that the function is going downwards all the way from the left until x=4. Thus, the function is decreasing from for all values to the left of 4. In interval notation, this is:
[tex](-\infty,4)[/tex]
So, the function is increasing over: [tex](4,\infty)[/tex]
And it's decreasing over: [tex](-\infty,4)[/tex]
And those are our answers :)
Important Notes:
Note that we do not use brackets with the 4. This is because the function is only increasing to the right of 4 and decreasing to the left of 4. At exactly 4, the function is still; it is neither increasing nor decreasing. Thus, x equals exactly 4 will be in neither of our intervals.

Filling Balloons
You are planning a surprise birthday party, and you would like to decorate with some
helium-filled balloons. You plan to use two different sizes of balloons. You will need to
purchase balloons and helium based on your party plans. The volume and cost of balloons
and helium tanks are listed below:
• The volume of each small balloon is 300 in."
3
• The volume of each large balloon is 1000 in.'.
• One package of 50 small balloons costs $2.59.
• One package of 24 large balloons costs $1.99.
• One small tank of pressurized helium can fill 20 ft of balloons. It costs $10.49.
You would like to fill at least 30 of each size of balloon for your party, but you would like to
use all of the helium you purchase. In addition, you would like to spend the least money
possible for balloons.
Task Description
Use functions to determine the number of balloons you need and how much your
supplies will cost.
Answer:
The number of small balloons = 46
The number of large balloons = 159
The number of bottles of helium gas = 5
The total cost of the supplies = $68.97
Step-by-step explanation:
The volume of each small balloon = 300 in.³
The volume of each large balloon = 1000 in.³
The cost of one package of 50 small balloons = $2.59
The cost of one package of 24 large balloons = $1.99
The volume of one small tank of pressurized helium = 20 ft³
The volume cost of one small tank of pressurized helium = $10.49
By conversion
20 ft³ = 34,560 in.³
The volume of 30 small balloons = 30 × 300 in.³ = 9,000 in.³
The volume of 30 large balloons = 30 × 1000 in.³ = 30,000 in.³
The volume taken by 24 large balloons = 24,000 in.³,
24 large balloons cost = $1.99
The volume taken by 50 small balloons = 15,000 in.³
50 small balloons cost = $2.59
Therefore, we buy more large balloons
We have;
A×300 + B×1000 = C×34,560
Given that all the helium will be used, the volume of helium will be a multiple of 300, therefore, when 5 bottles of helium is used, we have;
A×300 + B×1000 = 5×34,560 = 172,800 in.³
Given that there will be at least 30 of each balloon, gives;
We remove the minimum possible quantity (more than 30) of small balloons from 172,800 in.³ leaving multiples of 1,000s as follows;
Using Excel, the quantities of 36 and 46 small balloons give the same cost
For 46 small balloons
The volume of 46 small balloons = 13,800 in.³
Therefore, 172,800 in.³ - 13,800 in.³ = 159,000 in.³ = The volume of the large balloons
The quantity of the large balloons = 159,000 in.³/(1,000 in.³/balloon) = 159 balloons
Therefore, we have 46 small balloons, and 159 large balloons, with 5 small bottles of helium gas
The number of package of large balloons is 159/24 = 6.625 ≈ 7 packages
The cost of the 7 packages of large balloons = 7 × $1.99 = $13.93
The number of package of small balloons is 46/50= 0.92 ≈ 1 package
The cost of the 1 packages of small balloons = 1 × $2.59 = $2.59
The cost of the five bottles of helium = 5 × $10.49 = $52.45
$68.97
The number of small balloons = 46
The number of large balloons = 159
The number of bottles of helium gas = 5
The total cost of the supplies = $68.97
At the same cost, we can also have;
The number of small balloons = 36
The number of large balloons = 162
The number of bottles of helium gas = 5
The total cost of the supplies = $68.97
Therefore, we can have 36 or 46 small balloons and 162 or 159 large balloons along with 5 bottles of helium gas with a total cost of $13.93 + $2.59 + $52.45 = $68.97.
In a recent year, the top-selling cookie in America was Nabiscos Chips Ahoy, with sales of $294.6
million. The total cookie sales for that year were $3,124 milion. What percent of the total cookie sales
was due to Chips Ahoy?
Answer:
9.43%
Step-by-step explanation:
Divide the Chips Ahoy sales by the total sales, then multiply by 100
(294.6/3,124) x 100
= 9.43%
So, 9.43% of the total cookie sales were from Chips Ahoy

Diego says a quadrilateral with four congruent sides is always a regular polygon. Mai says it never is one. Do you agree with either of them?
Help please!!!
Answer:
mai is correct
Step-by-step explanation:
a quadrilateral with four congruent sides is never a regular polygon it is a rhombus. hope this helps!
A regular polygon has four congruent sides and four congruent angles.
I do not agree with any of them, because both arguments are incorrect
For a polygon to be a regular polygon, the following conditions must be met
All four sides must be congruentAll four angles must be congruent (90 degrees)Some quadrilaterals with four congruent sides are:
Rhombus, Kite, Square, etc.
A rhombus has four congruent sides, but all four angles are not congruent.
This means that Diego's argument is incorrect
All sides and angles of a square are congruent.
Because Mai says such polygons can never be a regular polygon, then Mai's argument is also wrong.
Hence, I do not agree with any of them.

Explain why angle is considered a defined term in geometry.
Answer:
An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.
Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.

A construction company is setting up signs on 2 miles of road. If the company places a sign every 1 4 mile, how many signs will it use?
Every 1/4 mile it places a sign.
So we need to find out how many 1/4 mile there is in the total 2 miles.
To know that: We carry out 2 divide 1/4
2 / (1/4)
2 * 4/1
= 8
So there are eight (8), 1/4 miles on the 2 miles of road.
8

solve by factoring y²-4=3y
Answer:
(y + 1) • (y - 4)
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring y2-3y-4
The first term is, y2 its coefficient is 1 .
The middle term is, -3y its coefficient is -3 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
y2 - 4y + 1y - 4
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-4)
Add up the last 2 terms, pulling out common factors :
1 • (y-4)
Step-5 : Add up the four terms of step 4 :
(y+1) • (y-4)
Which is the desired factorization
Final result :
(y + 1) • (y - 4)
