To solve this question all you have to do is input the X and y coordinates and test each point in the question. To see which of those points. Have the left hand side equal to the right hand side after doing all of the operations.
So we have to find b we are going to try to isosiate b
4b - 3 > -1 now we are going to isosiate the b so add 3 from both side and get 4b > 2
A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
Answer: $7.90
Step-by-step explanation:
When we see how much she spent on the total cost of renting skates, getting in, and getting hot chocolate, we can see that she is going to subtract all of that from the total cost.
$15.00 - 2.25 = 12.75
12.75 - 2.15 = 10.60
10.60 - 1.35 = 9.25
9.25 - 1.35 = 7.90 remaining
We know that she payed 2.25 to get in, 2.15 for skate rental, and 1.35 for each hot chocolate she purchased which in this case is 2. We need to subtract all of this from 15 and get the final answer
