Answer:
0, 1
Step-by-step explanation:
The discriminant is b² - 4ac where we have ax² + bx + c, in this case a = -4, b = 12, c = -9 so D = 12² - 4(-4)(-9) = 0.
Because the discriminant is 0 that means that f(x) only has one solution for x meaning that it has only 1 x-intercept.
Answer: -20 1/12
Step-by-step explanation:
-8 + -11 = -19
-3/4 + -1/3 = -1 and 1/12
so -19 + -1 and 1/12 = -20 and 1/12
Answer:
700.058824 but rounded to the nearest tenth it would be 700.1.
Step-by-step explanation:
Answer:
75 degrees and 105 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees
So angle A + B = 180 or B = 180 - A
then A/B = 5/7
7A = 5B
7A = 5(180 - A)
7A = 900 - 5A
12A = 900
A = 75
then B = 180 - A = 180 - 75 = 105
