Answer:
20
Step-by-step explanation:
because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find
angle 5 = 135
angle 5 and 5x+35 are alternate interior angles, so they have the same value
135=5x+35
100=5x
20=x

Answer:
(8, -9), (11, -9)
Step-by-step explanation:
The points (5, 7) and (7, 7) are on a horizontal line in which the y-coordinates of all points are 7. The line has equation y = 7.
For a line to not intersect the line y = 7, it must be parallel to y = 7.
The answer is the pair of points which both have the same y-coordinate, and that y-coordinate is not 7.
From the choices you added to your comments, the only choice with two points with the same y-coordinate is (8, -9) and (11, -9). This is the answer.
Answer: (8, -9), (11, -9)
Answer:
C
Step-by-step explanation:
Given the logarithmic equation
First, notice that
So, there is no possible solutions, all possible solutions will be extraneous.
Solve the equation:
then
Hence, 
and

Answer:
7.6
Step-by-step explanation:
The relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(51°) = x/12
x = 12·cos(51°) ≈ 7.552
x ≈ 7.6
