Answer:
D) X = 11
Step-by-step explanation:
Solve for x
5x + 2 = 59
subtract 2 from both sides
5x = 57
divide both sides by 5
x = 57/5
this answer would be closest to x = 11 (11* 5 = 55)
Answer:
x = 15
Step-by-step explanation:
8x + 9 and 51 are same- side interior angles and sum to 180° , then
8x + 9 + 51 = 180
8x + 60 = 180 ( subtract 60 from both sides )
8x = 120 ( divide both sides by 8 )
x = 15

Answer:
x ≠ 1.
Step-by-step explanation:
In mathematics, anything divided by 0 is null. It is not valid. And so, in this case, x - 1 must never equal 0, but it can be any number other than 0.
x - 1 = 0
x = 1
That means that the domain of the function is x ≠ 1.
Hope this helps!
