Answer:
Hey there!
We can write this equation: 2x+4x=180
6x=180
x=30
Hope this helps :)
The two angles are supplementary angles. When added together they equal 180 degrees.
2x + 4x = 180
Combine like terms:
6x = 180
Divide both sides by 6:
X = 180/6
X = 30
Drag each value to the correct location on the equation. Each value can be used more than once.
Answer:
[tex]x=\frac{-b\pm \sqrt{b^{2}-4ac } }{2a}[/tex]
Step-by-step explanation:
If a quadratic equation is in the form of ax²+ bx + c = 0
Then the roots of this quadratic equation can be obtained by,
1). Factoring the expression.
2). By quadratic formula.
If we use the method to get the value of x or roots of the equation,
x = [tex]\frac{-b\pm \sqrt{b^{2}-4ac } }{2a}[/tex]
where a, b and c are the coefficients used in the quadratic equation.

Kellianne lined up the interior angles of the triangle along line p below.
Which statements are true for line p? Check all that apply.
It is a straight line with a measure of 360°.
It stays the same even if the angles in the triangle change.
The line will not be straight if one of the angles in the triangle is changed to an obtuse angle.
The line is only straight when one of the angles is a right angle.
It represents the sum of the measures of the interior angles of the triangle.
The line will not be straight if all the angles in the triangle are acute.
It combines the three interior angles of the triangle to form a straight line.
It is a straight line with a measure of 180°
Answer:
2. it stays the same even if the angles in the triangle change
a. the angles must add up to 180º. a straight line is equal to 180º, so as long as the angles add up to 180º, it will be a straight line.
5. it represents the sum of the measures of the interior angles of the triangle
a. Kellianne lined up the interior angles of the triangle. if added they equal 180º which is the measure of the straight line.
7. it combines the three interior angles of the triangle to form a straight line
a. same answers as previous
8. it is a straight line with a measure of 180º
a. refer to above

Find the value of x in the isosceles triangle shown below.
Answer:
sqrt of 41, or A
Step-by-step explanation:
You can cut the iscosles triangle into 2 right triangles as shown on the image, and the base of each will be 4, and the height 5.
The hypotenuse on a right triangle is the square root of the base squared added with the height squared, which would be 16+25, or 41. therefore, X is the sqrt of 41
Answer:
A. x = square root of 41

O 8(x)3x -
F () --3x+
O F1(x) = -4x+5
Of '(x) = 4x+4
Answer:
The inverse is -1/5x -4/5
Step-by-step explanation:
f(x) = -5x-4
y = -5x-4
Exchange x and y
x = -5y -4
Solve for y
Add 4 to each side
x+4 = -5y
Divide by -5
-1/5x -4/5 = -5y/-5
-1/5x -4/5 = y
The inverse is -1/5x -4/5
Answer:
[tex]\huge\boxed{f^{-1}(x) = -\frac{x+4}{5}}[/tex]
Step-by-step explanation:
[tex]f(x) = -5x-4[/tex]
Replace y = f(x)
[tex]y = -5x-4[/tex]
Exchange values of x and y
[tex]x = -5y -4[/tex]
Solve for y
[tex]x = -5y - 4[/tex]
Adding 4 to both sides
[tex]x + 4 = -5y[/tex]
Dividing both sides by -5
[tex]y = -\frac{x+4}{5}[/tex]
Replace y = [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x) = -\frac{x+4}{5}[/tex]
Can someone please help me out? I'd really appreciate it.
Answer:
The scaling factor is 4.
Step-by-step explanation:
To find the scaling factor from A to B, we must know that these are similar triangles. Since this is not stated in the problem, we will assume these are similar triangles.
Similar triangles simply have the same scaling ratio, allowing for any size triangle to be created with the same relative dimensions. With this in mind, let's check to see the multiple of each side by simply taking the sides of the triangle B divided by the sides of triangle A.
40 / 10 = 4
44 / 11 = 4
72 / 18 = 4
Notice how each of the sides from triangle B to triangle A has the same multiple, 4. This tells us that the scale from A to B is 4.
Hence, the scaling factor is 4.
Cheers.

Answer:
Balance = $14,723.06
Step-by-step explanation:
Given:
Principal (P) = $15,000
Interest Rate (R) = 7.5%
Time (T) = ¹/12
Monthly payment = $185.49
Required:
Balance of the loan at the end of 3 months using the formula for simple interest.
SOLUTION:
[tex] I = \frac{P.T.R}{100*12} [/tex]
First Month:
Principal => $15,000
Add interest => [tex](\frac{15,000*7.5*1}{100*12} )[/tex] => $93.75
= $15,093.75
Less payment => $185.49
= $14,908.26
Second Month:
Principal => $14,908.26
Add interest => [tex](\frac{14,908.26*7.5*1}{100*12})[/tex] => $93.18
= $15,001.44
Less payment => $185.49
= $14,815.95
Third Month:
Principal => $14,815.95
Add interest => [tex](\frac{14,815.95*7.5*1}{100*12})[/tex] => $92.60
= $14,908.55
Less payment => $185.49
Balance = $14,723.06HELLLPPPP..............

A furniture shop refinishes cabinets. Employees use one of two methods to refinish each cabinet Method I takes 1 hour and the material costs $6. Method II takes 2 hours, and the material costs $5. Next week, they plan to spend 260 hours in labor and $986 in material for refinishing cabinets. How many cabinets should they plan to refinish with each method?
Answer:
They should refinish 96 tables using method 1
They should refinish 82 tables using method 2
Step-by-step explanation:
Let
a = number of tables refinished using method 1
b = number of tables refinished using method 2
Time equation
a+2b=260 (1)
Cost equation
6a+5b=986 (2)
a+2b=260 (1)
6a+5b=986 (2)
Multiply (1) by 5 and (2) by 2
5a+10b=1,300 (3)
12a+10b=1,972 (4)
Subtract (3) from (4)
7a=672
Divide both sides by 7
a=96
Recall,
a+2b=260
96+2b=260
2b=260-96
2b=164
Divide both sides by 2
b=164/2
=82
They should refinish 96 tables using method 1
They should refinish 82 tables using method 2
A ladder is leaning against a wall. The ladder is 5 metres long. The top of the ladder is 3 metres above the ground. The top of the ladder is sliding down at 8 metres/second. At what rate is the bottom of the ladder moving away from the wall?
Answer:
it is moved away in .625 seconds
Step-by-step explanation:
i did 5 divided by 8 though this question is weriod
Assuming the ladder is leaning against the wall and there are no spaces in between (that doesn't make sense sorry), it is still at a rate of 8 meters per second because it is standing straight up. It is moving at the same rate, since it is the same ladder.

The Mali Empire of West Africa was known far and wide for the great wealth of its rulers. The empire fell in the year 1610
Let x represent any year. Write an inequality in terms of x and 1610 that is true only for values of x that represent years after the year the Mali Empire fell.
Answer:
[tex]x > 1610[/tex]
Step-by-step explanation:
Given that the empire fell in 1610
Required
Represent years after the fall of the empire using inequality
From the question, we understand that
1. x represent years
2. The empire fell in 1610
This implies that, years before (and including) 1610 are invalid and we only have to consider years after 1610;
Years such as 1611, 1612, 1613.......
All the aforementioned years are greater than 1610;
The keyword is greater than 1610
And this can be represented as [tex]x > 1610[/tex]
Please help me with this question. I need to submit today. Question number 4. Lhakpa is a name of the person.
Answer:
Known:
width: 1/3
length: 3/5
Ask:
the area of floor?
Solution:
We need to multiply the width and length first!
width × length
= 1/3 × 3/5
= 3/15
= 1/5
Next subtract the number of floor witch has full fraction 1/1, so
= 1/1 - 1/5
= 5/5 - 1/5
= 4/5
So, the area of the floor is 4/5

Identify each function as linear, quadratic, or exponential. ƒ(x) = 4x2 g(x) = 1 - x h(x) = 32x
Answer:
f(x) is quadratic. g(x) and h(x) are linear.
Step-by-step explanation:
So we have the three functions:
[tex]f(x)=4x^2\\g(x)=1-x\\h(x)=32x[/tex]
Linear functions are polynomials in which the highest degree is 1.
Quadratic functions are polynomials in which the highest degree is 2.
And exponential functions usually have a variable in the exponent (e.g. 2^x).
For f(x), the highest degree is 2. Thus, f(x) is a quadratic function.
For g(x), the highest degree is 1 and there are no variables in the exponent. Thus, g(x) is a linear function.
Similarly, for h(x), the highest degree is 1 and there are no variables in the exponents, so h(x) is also a linear function.
