If f(x)=5x-25 and g(x)=1/5x+5, which expression could be used to verify g(x) is the inverse of f(x)?

Hoochie [10]

we know that

if g(x) is the inverse of f(x)

then

g[f(x)]=x

$f(x)=5x-25\\$

$g(x)=\frac{1}{5}x+5$

$g(f(x))=\frac{1}{5} [5x-25]+5$ ------> this is the expression

$g(f(x))=x-5+5\\ g(f(x))=x$

therefore

the answer is the option

b) 1/5(5x-25)+5

Uhh help lol<br> 5.3x + y = 28.5 <br> 4.2x + 3.1y = 27.2<br> find x and y

navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

$y = -5.3x+28.5$

Next, substitute y in the bottom equation.

$4.2x + 3.1(-5.3x + 28.5) = 27.2$

$5.3x + y = 28.5$

Simplify.

$4.2x + -16.43x + 88.35 = 27.2$

Combine like terms.

$-12.23x + 88.35 = 27.2$

Isolate x on one side.

$-12.23x = -61.15$

Isolate x.

$x = 5$

Substitute x into $5.3x + y = 28.5$

$5.3(5) + y = 28.5$

Simplify.

$26.5 + y = 28.5$

Isolate y.

$y = 2$

$x = 5 \\y = 2$

Answer:

128 m^3

Step-by-step explanation:

The volume of the rectangular prism base is (8 m)(8 m)(10 m), or 640 m^3.

The triangular 'cap' has a base area of 64 m^2 and a height of 6 m, and thus a volume of (1/3)(64 m^2)(6 m) = 128 m^3
