2(x+4) = 1/2(4x-4)
Multiply through by 2:-
4(x + 4) = 4x - 4
4x + 16 = 4x - 4
4x - 4x = -4 - 16
0 = -20
This is obviously wrong so there is NO Solution (answer).
Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
Answer:
$1.935
Step-by-step explanation:
As the store is offering a 15% discount, you have to calculate the 15% of the price of the game app to find the amount of the discount:
Price of the game app= 12.90
12.90*15%=1.935
According to this, the answer is that the amount of the discount if you buy the game app during the sale is $1.935 and you would have to pay: 12.90-1.935= $10.965.
Answer:
D AND E
Step-by-step explanation:
Step-by-step explanation:
1. 64=1+3+5+7+9+11+13+15 that is a total of 8 odd numbers so n=8
2.((new-old)/old)×100%=percentual difference
so ((new-$55)/$55)×100%=20%
new-$55=$55×0.2
new=$55+$55×0.2=$66
