The graph below shows a system of equations: y = -x - 2 and y = 2x - 5. The x-coordinate of the solution to the system of equati
sergey [27]

ANSWER

The x-coordinate of the solution to the system of equations is 1.

EXPLANATION

The given equations are:

y = -x - 2

and

y = 2x - 5.

We want to find the x-coordinate of the solution to the system of equations.

We equate the two equations to obtain an equation in x.

This implies that,

2x-5=-x-2

Group similar terms to obtain:

2x+x=-2+5

Simplify

3x=3

Divide both sides by 3.

x=1

The x-coordinate of the solution to the system of equations is 1

scZoUnD [109]

Answer:

4160 cubic inches

Step-by-step explanation:

The dog carrier is in the shape of a rectangular prism (cuboid).

The volume of a rectangular prism is given as:

V = L * W * H

where L = length, W = width, H = height

The carrier is 20 inches long, 13 inches wide, and 16 inches high.

Therefore, its volume is:

V = 20 * 13 * 16\\V = 4160 in^3

The volume of the dog carrier is 4160 cubic inches.
