To find the answer, we need to see by how much 20 changed to 30.
20 (1.5) = 30
So that means that
9 (1.5) = 13.5
answer:2x + 7
Step-by-step explanation:
subtract polynomial 1 from the sum
124+(2x+4) = 180
2x = 52
x = 26
Note: supplementary angles means that sum of the two angles is 180 degrees
Answer:
Choice A: . for all real numbers.
Step-by-step explanation:
We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points .
Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.
The same goes for choice D.
And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2
