Answer:
3x+15
Step-by-step explanation:
Answer: $49.75
Step-by-step explanation:
$53.50 is with the added 7%.
we want to find what the price is without the 7%
take that $53.50 is 100%
1% - 53.50/100 = 0.535
7% - 0.535 x 7 = 3.745
$53.50 - 3.75 = $49.75
Functions:graph B,mapping A, Table B
Grape B is a function because it passes the vertical line test ( meaning when I draw a vertical line any where on the graph the line only touched one point),mapping A is a function because each x value has only one y value same with table.
Non function: graph A, mapping B, Table A
Graph A does not pass vertical line test so it is not a function, mapping B and Table A both have an x value that has two y values and that is not a function.
Answer: x= -11
Step-by-step explanation: Substitute y for -9, and move 2 to the other side, which would be -9-2=-11. So x=-11
