Rate of change or slope. Hope it helps.
Answer:
x= -2 y= -1
Step-by-step explanation:
stack the 2 equations on top of each other and add them together
the 2x and -2x cancel out and you are left with -9y=9
this gives you y= -1
you plug the y value into one of the equations:
2x - (-1) = -3
2x+1 = -3
2x= -4
x= -2
The method used is Distributive Property.
<h3>What is Distributive property?</h3>
The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis.
Given:
(2x² - 1)(3x+2) = (2x²)(3x) + (2x²)(2) + (-1)(3x)+(-1)(2)
Here the property used is Distributive property.
Because distributive property in this way
a*(b+c)= a*b+ a*c
This is how a is being multiplied by with b and c.

We know Bianca delivers 100 newspapers every 2 days.
So we must find out how many papers she delivers in 1 day.
100 ÷ 2 = 50
Bianca delivers 50 papers in 1 day.
Now we must multiply that by 7.
50 × 7 = 350
We get 350 papers per week.
The answer is 350.
