If the coefficient squared is greater than one (multiplication), it stretches the graph vertically by the factor of the coefficient.
If the coefficient squared is less than one (division), it compresses the graph vertically by the factor of the coefficient.
When two adjacent angles form a straight line, they are called linear pair. They add up to 180.
j + 102 = 180
j = 180 - 102
j = 78
We're not given the choices but we don't need them.
The only way this problem is tractable to a middle or high schooler is if the polynomial is perfect cube; a little thought yields
To find the inverse let's call f(x) x and call x y and solve for y.
![y-2 = \sqrt[3]{x}](https://tex.z-dn.net/?f=y-2%20%3D%20%5Csqrt%5B3%5D%7Bx%7D)
![y = 2 + \sqrt[3]{x}](https://tex.z-dn.net/?f=y%20%3D%202%20%2B%20%5Csqrt%5B3%5D%7Bx%7D)

Answer:
C, Length = 39.4 cm; width = 7.9 cm
Step-by-step explanation:
The permimeter of a rectangle is 2 times the width + 2 times the length or 2(l + w)
The length is 4 times w plus 7.8.
So: 2w+2(4w+7.8)=94.6
= 2w+8w+15.6=94.6 (Factor out the brackets)
= 10w+15.6=94.6 (Combine like terms)
= 10w=79 (Subtract 15.6 from both sides)
= w=7.9 (Divide both by 10).
So, the width is 7.9 cm and the length is 39.4 cm (4 * 7.9 + 7.8)
