Answer:
m = +/- 12
Step-by-step explanation:
A quadratic function has only one x-intercept when the discriminant is equal to 0. The discriminant is b^2 - 4(a)(c).
When we plug in what we know, we have:
m^2 - 4(18)(2) = 0.
Then using algebraic properties, solve for m.
m^2 - 144 = 0
m^2 = 144
m = +/- 12
When you plug in positive or negative 12, and then factor you will see that it comes out to a difference of squares, proving that there is only one x-intercept.
Answer:
C. x + 6
Step-by-step explanation:
Start by factoring completely the numerator and the denominator.
2x + 12 = 2(x + 6)
x^2 + 7x + 6 = (x + 1)(x + 6)
The only common factor is x + 6, so the GCF is x + 6
7 would be the smallest number; 7 * 28 = 196 and the square root of 196 is 14.
Don't think that you can do this in distributive property but 96 divided by 6 is 16
Answer:
a. 8, 14, 20
x=5 when y=11
Step-by-step explanation:
Just subsititute the x in the equation with the number that represents x.
