The answer is B reflection across the y axis
First, distribute the 2 on the right side of the equation so you get 4a-26. Then add 26 to both sides so you have 7a+21 =4a. Subtract 7a and get 21 = -3a. Divide by -3 and your final answer is -7.

Answer:
2
Step-by-step explanation:
The degree of a function is the highest power any single term is raised to.
x^2 is the term that has the highest degree, so in this case, the degree is 2.
For example; in x^5-x^4-3x^3; the degree would be 5 because the highest power x is raised to is 5.
Answer:
no
Step-by-step explanation:
The 5x+30 is the supplementary angle of the interior one:
180 - 5x - 30 = -5x + 150
Then they have to add up to 180:
4x-9 + 2x+3 -5x + 150 = 180
which simplifies to x = 36
So the angles would be 135, 75 and -30, which is impossible!
