To find the number of zeros in the quadratic equation we factorize it as follows:
f(x)=x²+6x+18
solving using completing square methods we obtain:
x^2+6x=-18
c=(b/2a)^2=9
thus
x²+6x+9=-18+8
x²+6x+9=-9
(x+3)²=-9
hence
x=-3+/-3i
the roots are:
x=-3+3i or x=-3-3i
Answer:
10 aerobic classes
Step-by-step explanation:
For non- members:
10 x 6 = $60
For members:
10 x 5 = $50 + $10 (Membership fee) = $60
Answer:
Step-by-step explanation:
f(x) = |2x−1|+3, reflected over the y-axis becomes
g(x) = |-2x−1|+3
We needed the point (0.5, 3) to go to the other side of the y-axis to get the point (-0.5, 3).
105 because 4*18+33 equals 105
