Answer:
The third set
Step-by-step explanation:
The third set does not a represent a function because you cannot have the one x value produce two different y values.
Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, - 2) and (x₂, y₂ ) = (4, 3)
m = 
= 
= 1
Its true for integers if you are using the associative property in addition or multiplication ONLY.
R1t+t/2.5=1, we are told it takes both 1.5 hours so
1.5r+0.6=1
1.5r=0.4
r=4/15
So for this other pipe to fill the pool by itself...
4t/15=1
4t=15
t=15/4
t=3.75 hours
check..
4t/15+t/2.5=1
(4t+6t)/15=1
10t=15
t=15/10
t=3/2
t=1.5 hours, correct (for both pipes filling the pool)
Answer:
Answer below Please give brainliest!!
Step-by-step explanation:
Sue Black: 8x5=40 hours 40 x $6.75 = $270
Jerry Atrix: 7.25 + 3 + 6.75 + 8 + 5 = 30 hours
30 x $5.15 = $154.50
Sam Ting: 7.75 x 5 = 38.75 hours
38.75 x $8.75 = 339.0625 = $339.06
