Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
Answer:yes
Step-by-step explanation:
Part A: 680-960d= 52,000
Part B: Answer $54.875
Do inverse operation
Add 680 to both sides
Then divide 960 to both sides
Hello there!
6.55 ÷ 10 = .655
1 pound would cost about $0.65
First of all, if we want to graph this we will need to make it into slope intercept form
2x - y = 3
add y to both sides
2x = y + 3
subtract 3 from both sides
2x - 3 = y
flip the equation
y = 2x -3
we now know that the y-intercept is at (0, -3)
using that we plot the first point
The slope is 2
(this means up 2 over 1)
using that we make a line
(I'm sure you can graph it ;D)
Hope this helps :)
