Answer:
(- 5, 0) and (3, 0)
Step-by-step explanation:
Given
f(x) = x² + 2x - 15
To find the x- intercepts let f(x) = 0, that is
x² + 2x - 15 = 0 ← in standard form
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5 ← left x- intercept
x - 3 = 0 ⇒ x = 3 ← right x- intercept
The slope interception is going to be y=15
Answer:
A= 0.4 cents per cabbage
B= represents 10 cabbages is $4
Step-by-step explanation:
work for A 2 divided by 5 = 0.4
Y=0.6x+5 is the slope of a line parallel to the line -3x+5y=-10
