The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
Answer:
$22.40
Step-by-step explanation:
32 - 25.60 = 6.40
6.40/32 = 0.2
0.2 X 100 = 20%
100 - 20 = 80
28/100 X 80 = 22.40
Answer:
36400
Step-by-step explanation:
Answer: 200 texts
explanation:
use y = mx + b
y = cost of phone bill
m = price per text
x = # of texts
b = price of phone for the month
jon’s bill: y = .15x + 20
ed’s bill: y = .10x + 30
set them equal to each other bc you want to find how many texts for their bill to be equal
.15x + 20 = .10x + 30 (subtract .10x and 20 from both sides)
.05x = 10
x = 200 texts
