Answer:

The solution of this system of equations is (3 , -8)

Step-by-step explanation:

The given system is

x + 2y = -13

12x + 5y = -4

We make x the subject of the first equation and put it into the second:

$x = - 13 - 2y$

We put this expression for x into the second equation

12(-13-2y)+5y=-4

-156-24y+5y=-4

-24y+5y=-4+156

-19y=152

y=-8

We substitute y=-8 into x=-13-2y to get:

$x = - 13 - 2( - 8) = 3$

The solution of this system of equations is (3 , -8)

The graph below shows the time Andrea spent reading one day. Write a few sentences to describe the relationship between the time

Alex777 [14]

Answer:

Step-by-step explanation:

Well, there are several relationships you can describe. As time increases how does number of pages react? Like does it increase or decrease. Is it always increasing or decreasing by the same amount? If it's not all the same how do different parts look different.

There aren't any actual numbers, so you can't say specifically how they relate, like you can't say she read 5 pages a minute or something.
