Answer:
{-1,2,3,4}
Step-by-step explanation:
The domain is the input values
(3,7),(4,1),(-1,-8),(2,2),(4,-1)
(3,4,-1,2,4)
We do not list the repeats
(3,4,-1,2)
(-1,2,3,4)
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
x = 5 x = 4
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
1/4--1/2=0.75
This is less than 2 which you get from 1/2 times 2 which =1
1+1=2
Answer:
Runner 1 has the fastest pace
Step-by-step explanation:
The first one we need to find the slope
m = (y2-y1)/(x2-x1) = (40-0)/(4-0) =40/4 = 10 minutes per mile
The second is 8.5 minutes per mile
The third we need to find the slope
m = (y2-y1)/(x2-x1) = (90-72)/(10-8) =18/2 = 9 minutes per mile
