Answer:
(3,2)
Step-by-step explanation:
y = −2x + 8
y = x − 1
Substitute the second equation into the first equation for y
y = -2x+8
x-1 = -2x+8
Add 2x to each side
x-1+2x = -2x+8+2x
3x -1 = 8
Add 1 to each side
3x-1+1 = 8+1
3x =9
Divide by 3
3x/3 = 9/3
x=3
Now find y
y = x-1
y =3-1
y=2

Answer:
8, 12, 16, 20, 24
Step-by-step explanation:
To find the sales tax you’d need to find 9% of 87. You find this by using this template, x%/100%=y/z, x being the sales tax, y being 9% in cash, and z being the 87 dollars. You multiply the x value by the z value, (9 X 87=783) and then divide that product by 100%. This gives you the sales tax of 7.83, and when you add that to 87 you get $94.83. Subtract that from the 5 20 dollar bills ($100) and you are left with $5.27 change.
Y = mx + b slope(m) = -2/3 y-intercept(b) = -5
just simply put where these belong to find your equation.
y = -2/3x - 5
hope this helps, God bless!
