3x-12
Answer:
B
Step-by-step explanation:
The slope of the line that passes through the given points is (4-7)/(-3-1) = 3/4.
Since parallel lines have equivalent slopes, the answer is B.

Answer:
Step-by-step explanation:
Let Freda's sum = x
Donnie has 3/4 x
He spends 63 dollars. His sum is now
3/4x - 63
Now the equation looks like this
6(3/4x - 63) = x Remove the brackets
6*3/4 x - 378 =x
6 * 3/4 = 4 1/2
4 1/2 x - 378 = x Add 378 to both sides
4 1/2 x = x + 378 Subtract x from both sides
3.5 x = 378 Divide by 3.5
x = 378 /3.5
x = 108
Since x = 108, that's how much Freda had. (She spent nothing).
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
