Answer: y=7x-5

Step-by-step explanation:

(0,-5) (1,2)

y=kx+b

$\displaystyle\\k=\frac{y_2-y_1}{x_2-x_1} \\\\x_1=0\ \ \ \ x_2=1\ \ \ \ y_1=-5\ \ \ \ \ y_2=2\\\\k=\frac{2-(-5)}{1-0} \\\\k=\frac{2+5}{1} \\\\k=7\\\\Hence,\ y=7x+b\ \ \ \(0,-5)\\\\-5=7*0+b\\-5=0+b\\-5=b\\\\Thus,\ \ \ \ y=7x-5$

Philip wants to buy a lawn mower that is 25% off. The sale price is $48. What was the original price?

Hitman42 [59]

$64

48 would be 75% or 3/4 of the full price, so dividing it by 3 gives us 16, or 1/4. multiply by 4 to get 4/4, the whole price

Answer:

3. 4a(a + 1) - 15

step-by-step explanation:

1. (x +y)² + 11 (x + y) + 30

= x + y {(x +y) + 11} + 30

2. (a - b)² - 16(a - b) + 60

= (a - b){(a - b) - 16} + 60

3. 4a² + 4a - 15) - 15

4. 2x² + 5x + 2

= x(2x + 5) + 2
