Well it depends on what the tax will be (if you have to use tax) then add the fee
So for a, the y-intercept would be positive 2 (first equation) and the slope would be 3/1. When you graph the y-intercept, which you have to do first, you can use the slope to figure out the line. The same thing would happen with the second equation. -8 is the y-intercept and -2/1 is the slope. (Negative slope would be, in this case, down 2 right 1)
Answer:
6
Step-by-step explanation:
divide both sides of the equals by 5 to get p on its own
5p divided by 5 = p
30 divided by 5 = 6
Answer:
Step-by-step explanation:
Given equation of the quadratic function is,
y = x² + 5x - 7
Convert this equation into vertex form,
y = x² + 2(2.5x) - 7
= x² + 2(2.5x) + (2.5)² - (2.5)² - 7
= (x + 2.5)²- 6.25 - 7
= (x + 2.5)² - 13.25
Therefore, vertex of the function is → (-2.5, -13.25)
For the solutions,
y = 0
(x + 2.5)² - 13.25 = 0
x = (±√13.25) - 2.5
x = (±3.64) - 2.5
x = 1.14, -6.14
Solutions → (-6.14, 0) and (1.14, 0)
