Answer:

f(5) = 52

Step-by-step explanation:

$f(x) = 2x^{2} + 2$

We have to substitute x with 5.

f(5) = 2(5) ^2 + 2

f(5) = 2(25) + 2

f(5) = 50 + 2

f(5) = 52

Hope this helps!

Y=1/4x+7 y=1/2x+5 The y-coordinate of the solution to the system shown is _____.

Brilliant_brown [7]

Answer:

The y-coordinate of the solution to the system shown is 9

Step-by-step explanation:

$y=\frac{1}{4}x+7\\y=\frac{1}{2}x+5$

We need to solve these system of equations and find value of y

Let eq (1) be $y=\frac{1}{4}x+7$

and eq(2) be $y=\frac{1}{2}x+5$

Putting value of y from eq(2) into eq(1)

$y=\frac{1}{2}x+5=\frac{1}{4}x+7\\\\\frac{1}{2}x-\frac{1}{4}x=7-5\\\frac{2x-x}{4}=2\\\frac{x}{4}=2\\x=2*4\\x=8$

Putting value of x=8 in equation 1 to find value of y

$y = \frac{1}{4}x+7$

$y = \frac{1}{4}(8)+7$

$y =2+7$

$y =9$

So, The y-coordinate of the solution to the system shown is 9
