erik [133]

Answer:

x = -4

Step-by-step explanation:

Distribute:

-2(x + 5) = -2

-2(x) -2(5) = -2

Multiply:

-2(x) -2(5) = -2

-2x - 10 = -2

Add 10 on both sides:

-2x - 10 = -2

+10 +10

-2x = 8

Divide by -2 on both sides:

-2x = 8

/-2 /-2

x = -4

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x). ...
If you can't seem to solve for x, then try graphing the function to find the range.

A rectangular has sides that measure 9 centimeters by 12 centimeters by 23 centimeters. Joan filled the container to its brim wi

Svet_ta [14]

So you need to find the volume of the rectangular prism and the equation for that is V=l×w×h. If you plug those numbers in you'd get 9×12×23=2,484. If you multiply 2,484 by $\frac{1}{3}$ because you'd have to pour out $\frac{1}{3}$ of the water out so that it's only $\frac{2}{3}$ of the volume of water is left. 2,484× $\frac{1}{3}$ = 828mm.
