Answer:
(A) Your friend will save $282.
(B) Your friend will get 23.5% off the original price of the mattress.
Step-by-step explanation:
We first need to find out the price of the mattress after the 15% discount. Our first step is to find what 15% of 1,200 is. We can do this by multiplying the two numbers.
1,200 x 15% -----> 1,200 x 0.15= 180.
15% of $1,200 is $180.
Next subtract $180 from $1,200, which equals $1,020. We can now apply the 10% off internet coupon.
1,020 x 10% ------> 1,020 x 0.10= 102.
10% of $1,020 is $102.
Next we subtract $102 from $1,020 and we get $918, the final price of the discounted mattress.
We subtract to see how much money the friend saved.
$1,200 - $918= $282.
We can get the percentage by dividing $282 by $1,200.
282 / 1200= 0.235 decimal form ----> 23.5%
Given the function f, match the function g with a transformation of f.
f(x) = x2 + 1, g(x) = (x - 2)2 + 1
☆☆☆☆☆☆☆☆a) f(x + 2)
b) f(x) + 2
c) f(x) - 2
d) f(x - 2)
The transformation that occured was a horizontal shift to the right of all the x's.

Answer:
x = 6 y = -9 (I took a complicated route so if my explanation doesn't make sense It's fine)
Step-by-step explanation:
DAY = FUN
F = (7x+2y) = 24
If DAY = FUN then D = F making (7x + 2y) = 24
This means A = U so you have to find U with 24+126=150
A triangle is 180 degrees so you would do 180-150=30
U = 30
This also makes (8x+2y) = 30
8x + 2y = 30
-8x -8x
2y = 30 - 8x
Divide everything by 2
y = 15 - 4x
Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24
Multiply it 7x + 30 - 8x = 24
Add like terms -x + 30 = 24
Subtract 30 -x = -6
Divide by -1 x = 6
Now take one of the equations and plug it in 7(6) + 2y = 24
Multiply 42 + 2y = 24
Subtract 2y = -18
Divide by 2 y = -9
