Hello!
Since the angles are alternate interior angles they equal each other
5x - 28 = 3x + 12
Now you solve this algebraically
5x - 28 = 3x + 12
Subtract 3x from both sides
2x - 28 = 12
Add 28 to both sides
2x = 40
Divide both sides by 2
x = 20
Now we put x into the equation we are wanting to find out
5x - 28
5(20) - 28
Multiply
100 - 28
Subtract
72
The answers are x = 20 and 5x - 28 = 72°
Hope this helps!

Answer:
y = (x -5)^2(x^2 +1)
Step-by-step explanation:
The zero at x=5 means that (x-5) is a factor. The multiplicity of 2 means that factor occurs twice (is squared). The remaining 2nd degree factor can be anything. In this equation, we have elected to make it have complex zeros.
y = (x -5)^2(x^2 +1)
Answer:
2/3
Step-by-step explanation:
when you simplify 4/6 you can get to 2/3 and that's your answer
Answer:
The slope is m=2.145.
The y-intercept is b=-1.33.
Step-by-step explanation:
We have this data:
- The mean and standard deviation for x are 5.43 and 1.12, respectively.
- The mean and standard deviation for y are 10.32 and 2.69, respectively.
- The correlation is 0.893.
We have to calculate the slope and the y-intercept of the least-squares line.
With the given data, we can calculate the slope m as:
Then, the y-intercept is calculated as:
