2. Is the point (-3,-4) the solution to the system of
equations: SHOW ALL YOUR WORK.

y = 2x + 2

-4 = 2(-3) + 2

-4 = -6 + 2

-4 = -4

y = x - 1

-4 = -3 - 1

-4 = -4

It is the solution

Step-by-step explanation:

Yes, it is the solution to the system.

Explanation:

The point (-3,-4) means that x = -3 and y = -4 pair up together.

Let's plug those values into the first equation and simplify

y = 2x+2

-4 = 2(-3)+2 replace x with -3; replace y with -4

-4 = -6+2

-4 = -4 ... we get a true equation

Let's repeat for the other equation as well

y = x-1

-4 = -3-1

-4 = -4 this is also true

Since both equations are true, this means (-3,-4) is the solution to the system. The two lines intersect at (-3,-4).

which of the following can speed up the rate at which the liver breaks  

down alcohol?

question 1 options:

carbohydrates  

coffee  

nothing  

high-protein meals  

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
