I believe its additive Inverse Property
Answer:
(9,-2)
Step-by-step explanation:
9 is on x and y is -2
(x,y) is the rule so here ya go hope it helps :)
Well, without any prices, I can’t give you a number. And someone else may have a simpler way to do this.
But we’ll call the original bill x.
After the 10% off coupon, the bill is 0.9x
Adding tax = 0.07(0.9x) + 0.9x
Adding a tip = 0.20[0.07(0.9x) + 0.9x)]
If you have numbers to plug in, put them in a comment below & I’ll help more.
Answer:
Step-by-step explanation:
A
y = 7 - x
y = 7 - 2
y = 5
B
y = x^2 - 1
y = (2)^2 - 1
y = 2*2 - 1
y = 4 - 1
y = 3
C
y = x + 14
I'm going to assume that you mean (x + 14)^3
y = (x + 14)^3
y = (2 + 14)^3
y = 16^3
y = 4096
If you really do mean what it says, then
y = 2 + 14^3
y = 2744 + 2
y = 2746
