Answer:
12
Step-by-step explanation:
(x - 1)(x+3)^2
expanding
= (x - 1)(x^2 + 6x + 9)
= x^3 + 6x^2 + 9x - x^2 - 6x - 9
= x/63 + 5x^2 + 3x - 9
Answer:
y = - 2x + 3
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 ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = = - 2
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation of line
