Answer:
y = 4x -5
Step-by-step explanation:
First, find the slope by subtracting 11 by 3 and 4 by 2. The slope is 8/2, or 4. This is your current equation: y = 4x + b. Plug in one of your coordinates into the equation; it doesn't matter which one. However, I'm going to use the first point so it should look like this: 3 = 4(2) + b. 4 times 2 equals 8, so it should look like this: 3 = 8 + b. Subtract 8 from both sides to get -5 = b. Go back to your original equation and plug in -5 for b. This is your final equation: y = 4x -5. Hope this helped!
Answer:
x=0 i think
Step-by-step explanation:
3(x-1) equals 3x-3=5x-3 then you move the 5 to the other side but as a -5 with is -2x then you move the -3 on the left to the right as +3 then that cancels so then you’re left with x=0
Answer:
0

Answer:
Step-by-step explanation:
Hello
let's say that the price of the book was x
the price after a 20% discount is x - 20%*x = x*(1-20%)=x*(1-.20)=0.8*x
and this is $72 so we can write that
0.8*x=72
and then divide by 0.8 both parts
x = 72/0.8=90
So the list price value of the book is $90
and we can verify as 90 - 20%*90 = 90 - 18 = 72
Hope this helps
