A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
Answer:
4296 kg
Step-by-step explanation:
40/100 = x/7160
716 times 6 is 4296
2x^2+9x-6 i found this by subtracting 3x^2+7x from the other equation
The answer is A,
. This is because when plugging in -2 for x, the expression will look like this:
. To make the exponent positive, you have to flip it into a fraction. Then it will be
. Lastly, you simplify the denominator into 81.
