Answer:

f(x + 2) = 4x² + 16x + 13

Step-by-step explanation:

f(x) = 4x² - 3

Then

f(x + 2) = 4(x + 2)² - 3

= 4(x² + 4x + 2²) - 3

= 4(x² + 4x + 4) - 3

= 4x² + 16x + 16 - 3

= 4x² + 16x + 13

Find the solution of the system of equations.<br> 10x+10y=40 <br> 5x+3y=8

ddd [48]

Answer:

x = -2 & y = 6

Step-by-step explanation:

$10x+10y=40$

$10x+10y+ -10y=40+-10y$

$10x=-10y+40$

$\frac{10x}{10} =\frac{-10y+40}{10}$

$x=-y+4$

$5x+3y=8$

$5(-y+4)+3y=8$

$-2y+20=8$

$-2y+20+-20=8+-20$

$-2y=-12$

$\div2$

$y=6$

$x=-y+4$

$x=-6+4$

$x=-2$

Hope this helps.
