Ok, so what this question is really asking you is: 
What is 
and that equals 
Now because the the number is 2.4 plot that point
The answer to this problem is B
Answer:
x = 70 and the labeled angles are 110 and 70
Step-by-step explanation:
This is a trapezoid, the bases are parallel.
Since the bases are parallel, given two angles are supplementary and their sum is equal to 180:
x + 40 + x = 180 add like terms
2x + 40 = 180 subtract 40 from both sides
2x = 140 divide both sides by 2
x = 70 and the labeled angles are 110 and 70
Answer: Choice D
Explanation:
We have the two points (2,2) and (2,-2) which have a repeated x coordinate. This is not allowed if we wanted a function. A function must have any x input lead to exactly one and only one output (assuming the input is in the domain).
Answer:
x = 0
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
First, add 7 to both sides:
9x - 7 (+7) = - 7 (+7)
9x = -7 + 7
9x = 0
Next, divide 9 from both sides:
(9x)/9 = (0)/9
x = 0/9 = 0
x = 0 is your answer.
