(x + 8)(x - 5)
= x (x - 5) + 8(x - 5)
= x² - 5x + 8x - 40

Answer:
y = - 4
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (3, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of line
Answer:
x <-12
Step-by-step explanation:
-1/2x > 6
Multiply each side by-2. This will flip the inequality
-2 *-1/2x < 6*-2
x <-12
