Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
Substitute x + 1 as x in the equation of the function:
![r(x)=x^3+x+1\\\\r(x+1)=(x+1)^3+(x+1)+1=x^3+3(x^2)(1)+3(x)(1^2)+1^3+x+1+1\\\\=x^3+3x^2+3x+x+2=x^3+3x^2+4x+2](https://tex.z-dn.net/?f=r%28x%29%3Dx%5E3%2Bx%2B1%5C%5C%5C%5Cr%28x%2B1%29%3D%28x%2B1%29%5E3%2B%28x%2B1%29%2B1%3Dx%5E3%2B3%28x%5E2%29%281%29%2B3%28x%29%281%5E2%29%2B1%5E3%2Bx%2B1%2B1%5C%5C%5C%5C%3Dx%5E3%2B3x%5E2%2B3x%2Bx%2B2%3Dx%5E3%2B3x%5E2%2B4x%2B2)

The answer is A.
The numbers under the x and y represent the domain (x) and range(y) for ordered pairs. The -5 (under x) has the arrow toward the 3 (under y) so the answer for that pair would be (-5, 3)
Answer:
x= 8 + 2y/3
Step-by-step explanation:
6x = 48+4y
x = 48/6 + 4y/6
simplify
x= 8 + 2y/3
Yes ok it is with a common
