Answer:
C
Step-by-step explanation:
the statement (y<1/2x -4) reads "y is LESS than 1/2 x -4."
to fulfil this statement, follow these steps.
1) graph the line 1/2x -4, there will be a yintercept at (0,-4). Also the slope will be increasing (left to right) because 1/2 has no negative sign before it.
2) recognize the inequality sign. In this situation, the solution does NOT INCLUDE THE LINE, rather it includes the area BELOW/LESS THAN the line. If this, < had a line under it, it would mean less than OR equal to.
3) know that if the line is not included, the line will be broken. If the line IS included, which it is not, it would be a solid line.
Answer:
C
Step-by-step explanation:
First, graph the equation:
The y-intercept is -4.
And the slope is 1/2, an upward sloping line.
So, our graph should be either A, B, or C.
D is not correct, so eliminate that.
So, our inequality is:
[tex]y<\frac{1}{2}x-4[/tex]
Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.
Thus, eliminate A and B.
So, C is our answer
Further notes:
The inequality sign means that y is less than the equation. In other words, our shaded region should be below the line.
In C, the shaded area is indeed below the line.
So, C is indeed our answer :)

If A=kr² and V=kr³, find the percentage increase in A and V if r is increased by 20%
Answers
Answer:
The percentage increase in A is 44%. The percentage increase in V is 72.8%.
Step-by-step explanation:
The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.
For example, let's say that k = 5 and that r = 10.
[tex]A=kr^{2}[/tex] ⇒ [tex]A= 5 * 10^{2} =500[/tex]
[tex]V=kr^{3}[/tex] ⇒ [tex]V= 5 * 10^{3}= 5000[/tex]
The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.
[tex]10*1.2=12[/tex]
Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12
[tex]A=kr^{2}[/tex] ⇒ [tex]A=5*12^{2}=720[/tex]
[tex]V=kr^{3}[/tex] ⇒ [tex]V=5*12^{3}=8640[/tex]
Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:
[tex]Percentage Increase = \frac{final - initial}{initial} * 100[/tex]
Percentage Increase for A
Initial value: 500
Final Value: 720
[tex]Percentage Increase = \frac{720-500}{500} * 100 = 44%[/tex]
Percentage Increase for V
Initial value: 5000
Final Value: 8640
[tex]Percentage Increase= \frac{8640-5000}{5000} *100 = 72.8%[/tex]
The percentage increase for A is 44% and the percentage increase for V is 72.8%.
Hope this helps!

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]

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

solve by factoring y²-4=3y
Answers
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)

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!!!
Answers
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.

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.
Answers
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.
