Solve the system using elimination.
x-2y = - 12
- x + 4y = 20

x=-4

y=4

Step-by-step explanation:

Isolate a variable and plug into the other equation. Then solve for the variable and plug into one of the original equations.

Step-by-step explanation:

x-2y=-12

-x+4y=20

2y= 8

y =4

x - 2(4) = -12

x - 8 = -12

x = -4

(-4, 4)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
