sweet [91]

Answer:

z = 5/2y -1

Step-by-step explanation:

We observe that z has ...

1 added
the sum multiplied by 2/5

To solve for z, we undo these operations in reverse order.

$\dfrac{2}{5}(z+1)=y\qquad\text{given}\\\\z+1=\dfrac{5}{2}y\qquad\text{multiply by 5/2}\\\\\boxed{z=\dfrac{5}{2}y-1}\qquad\text{subtract 1}$

Given the function f(x)=4x^8+7x^7+1x^6+1 What is the value of f(−2)?

qwelly [4]

f(x)=4x^8+7x^7+1x^6+
∴ f(-2)=4(-2)^8+7(-2)^7+1(-2)^6+1
∴ f(-2)=(4x256) + (7x-128) + (1x64) +1
∴ f(-2)=1024 - 896 + 64 +1
∴ f(-2)= 193
