Answer:
D. 68+(6x+4)=180
x = 18
Step-by-step explanation:
"Supplementary angles" are angles that add up to 180°
So we add the twi angles 68+(6x+4) and that equals to 180°.
68 + 6x + 4 = 180
add 68 and 4
72 + 6x = 180
subtract 72.
6x = 108
divide by 6.
x = 18
The numerator of this function given may be factored out as follows,
x² - 2x - 15 = (x - 5)(x + 3)
Given that the expression x - 5 appears in both the numerator and the denominator, we can cancel them and the new function becomes,
f(x) = x + 3
which is continuous at 5.
Answer:
b
Step-by-step explanation:
7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
