How does the graph of g(x) = x+ 5 compare with the graph of the parent

vlada-n [284]

Answer:

C. The graph of g(x) is shifted 5 units up.

Step-by-step explanation:

The transformation shown shows a vertical translation.

$f(x)=x\pm d\\\\\text{Vertical translation up/down 'd' units.}$

The graph would move f(x) five units up.

Hope this helps.

Write the equation for the area of a triangle with a height that is 5 more than twice its base using one variable. Please help m

zysi [14]

Answer:

$A=b(b+\frac{5}{2} )$

Step-by-step explanation:

hey there!!!

we know already that the area of a triangle is given as

$A=\frac{1}{2}b *h$

where b= base

and h= heigth

Given that the height is 5 times more than twice it base

let h= 2b+5

Now we substitute h=2b+5 in the area of the triangle

$A=\frac{1}{2}b * (2b+5)$

$A= \frac{2b^2}{2} +\frac{5b}{2}$

$A= b^2+\frac{5b}{2}\\\\A=b(b+\frac{5}{2} )$
