Answer:
Below.
Step-by-step explanation:
In total there are 8 kids. Each cupcake is 2.75 so 8x2.75= 22 now the total is 46.00 So? 46-22 = 24. 24 divided by 2 = 12.
I Divided by 12 because they said cost of each individual cookie.
Answer:
y=1/2x+4
Step-by-step explanation:
to find the slope you need to know the change in y over the change in x
(0,4) and (8,8)
8-4/8-0
slope is 1/2
Answer:
3.5
Step-by-step explanation:
So maybe it’s 5, it’s equivalent to the side with 6, just shorter
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
