i dont know im so sorry i really need points someone took all mine by reporting them and i need to ask a question for an assignment due in 10 min and i need help again im so sorry
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
y =-2/3-5x
The slope intercept form of a line is
y = mx+b where m is the is the slope and b is the y intercept
Rewriting the equation
y = -5x-2/3
The slope is -5 and the y intercept is -2/3
Step-by-step explanation:
replaced f(x) with 5
5= x^2 +4
5 -4 = x^2
1 = x^2
take the square root on both sides
- 1 or 1 = x
Answer:
(4x +3)²
Step-by-step explanation:
The form of a perfect square trinomial is ...
(a +b)² = a² +2ab +b²
The factors are easily found as the square roots of the first and last terms.
16x² +24x +9
= (√(16x²) +√9)²
= (4x +3)²

Answer:
Option B). x = -9, -2 and 8.
Step-by-step explanation:
The given function is f(x) = x³ + 3x² -70x - 144 and f(-9) = 0, f(-2) = 0, f(8) = 0
We have to find the solutions to the equation x³+ 3x² = 70x + 144
Now we rewrite the function in the equation form as
x³ + 3x² - 70x - 144 = 0
x³ + 3x² = 70x + 144
we know for the values of x = -9, -2, and 8 value of the function is 0. So when we rewrite the function in the form of an equation, -9, -2 and 8 will be the zero factors of the equation.
So solutions of the equation are x = -9, -2 and x = 8.
