Answer:
x = 9
Step-by-step explanation:
We are going to isolate x
14 - x = 5
subtract 14 from 5
-x = -9
multiply both sides by -1 to make x positive
x = 9
Answer:
Step-by-step explanation:
discriminant = (-24)² - 4(9)(16) = 0, so there are two identical roots.
That eliminates choices 2 and 4.
Quadratic formula
x = [24 ± √(24² – 4·9·16)] / [2·9]
= 24 / 18
= 4/3
9x² - 24x + 16 = 9(x-4/3)² = (3x-4)²
Answer:
<1 = <8
Step-by-step explanation:
An angle that will form a pair of alternate exterior angles with <1 will be the angle that is found outside of the parallel lines but on the opposite side of the transversal that cuts across the two parallel lines.
<8 is an exterior angle, and also is alternate angle to <1. It forms a pair of alternate exterior angles pair with <1.
Therefore, <1 = <8
