2/5(x - 4) = 2x
2/5x - 8/5 = 2x....multiply everything by 5
2x - 8 = 10x
-8 = 10x - 2x
-8 = 8x
-8/8 = x
-1 = x <===

Answer Step-by-step explanation:

$\huge\boxed{A)-1}$

$The~average~rate~of~change~of~the~given~quadratic~function~on~the$ $interval~0$ ≤ x ≤ $4$ $is~the~slope~of~the~secant~line~connecting~the~points~(0,f(0))~and~(4,f(4)).$

$The~average~rate~of~change~is:$

$=\frac{f(4)-f(0)}{4-0}$

$Now,from~the~graph,f(0)~is~0~and~f(4)~is~-4.$

$We~plug~in~these~values~to~obtain;$

$=\frac{-4-0}{4-0}$

$And~then,this~simplifies~to:$

$=\frac{-4}{4}$

$which~is~obviously:$

$=-1$

$Thus,~the~average~rate~of~change~for~the~given~quadratic~function$ $whose~graph~is~shown~on~0$ ≤ x ≤ $4~is~=-1.$

Suppose that $1,000 is deposited into an account that yields

Lana71 [14]

ANSWER : $1,215.51

P= Principal = $1000
R= rate = 5% = 0.05
N= number or periods in 1 year (1 time pre year)
T= time expressed in years = 4 years

A= P (1 + r/n) nxt
= 1,000 (1+ 0.05/1) 1x4
= 1,215.51

A rectangle has length 72 cm and it’s width 56 cm. The other rectangle has the same area as this one, but its width is 21 cm. Fi

Kryger [21]

A = l*w

A = 72* 56

A= 4032

4032 = L*21

4032/21 =L

L =192
