Selection D is appropriate.
_____
I would write it differently.
.. 180 -x = "supplement of an angle"
.. 2x +20 = "20 more than twice the measure"
These are said to be equal, so I would write it as
.. 180 -x = 2x +20
Of course, adding x to both sides of this equation makes it
.. (2x +20) +x = 180 . . . . . . matches selection D
9/17 is equivalent to 9 divided by 17
Answer:
x = 7
x = -5
Step-by-step explanation:
Given
x² - 2x - 35 = 0
Consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (- 2)
The factors are - 7 and + 5, since
- 7 × 5 = - 35 and - 7 + 5 = - 2, thus
(x - 7)(x + 5) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 7 = 0 ⇒ x = 7
Answer: 4/3
In dividing by fractions, you flip the latter one over. 2/3 * 2=4/3.
Answer:
g(f): x -> 2(x-7)=2x-14 , g(f)(-1)=2*(-1)-14=-16
