Answer:
negative square root will result in zero x-intercepts
Step-by-step explanation:
there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts
in this case, a=-1, b=4, c=-12
[-4±√4² - 4(-1)(-12)] / 2(-1)
= [-4 ± √16-48] / -2
= -4 ± √-32 / -2
Answer:
39 gallons
Step-by-step explanation:
65 gallons ÷ 5 loads = 13 gallons per load
13 gallons per load • 3 loads = 39 loads
Simplifying:
2n-21=0.25n
We move all terms containing n to the left and all other terms to the right.
+2n-0.25n=+21
We simplify left and right side of the equation.
+1.75n=+21
We divide both sides of the equation by 1.75 to get n.
n=12
-3(-5x+2)+x=42
Distribute the -3 to the -5 and 2 so you would be left with
15x-6+x=42
Then you combine like terms and the x’s
16x-6=42
Add the 6 to the 42
16x=48
Then divide by 16 on both sides
X=3
I hope that helped.
