Answer:
b
Step-by-step explanation:
Given
x³ + 5x² - 9x - 45 ( factor the first/second and third/fourth terms )
= x²(x + 5) - 9(x + 5) ← factor out (x + 5) from each term
= (x + 5)(x² - 9) ← factor as a difference of squares
= (x + 5)(x - 3)(x + 3)
Answer:
-$73.73
Step-by-step explanation:
To get this answer, we must subtract 23.73 from -50, as Mr. Alexander is losing money by spending. Once we subtract, we get -73.73 dollars.
Hope this helps!
W + 3w = 90 is obviously wrong
Step-by-step explanation:
4x^2 - 20 = 5
4x^2 -25 = 0
4x^2 = 25
2x = 5, or -5
x = 5/2 , or -5/2
Answer:
y = x +2
Step-by-step explanation:
4y=4x+8
Slope intercept form is
y = mx+b so we need to solve for y
Divide each side by 4
4y/4 = 4x/4 +8/4
y = x +2
The slope is 1 and the y intercept is 2
