Answer:
(0, 12 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)
m =
=
= 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept
Thus the line crosses the y- axis at (0, 12 )
Answer:
d
Step-by-step explanation:
Let m = number of miles.
Each mile costs $2.35, so m miles cost 2.35m.
The flat fee is $2.
The total cost is
2.35m + 2
He can spend no more than $47, so he can spend $47 or less,
2.35m + 2 <= 47

Answer:
{0, 4 and -3}
Step-by-step explanation:
f(x)=x^3-x^2-12x can be factored, starting by taking out the 'x' factor:
f(x)=x^3-x^2-12x = x(x^2 - x - 12), and then by factoring the quadratic:
f(x) = x(x - 4)(x + 3) = 0
Then the zeros are {0, 4 and -3}.
