answer:
x = - 9/2
y = -10
Step-by-step explanation:
make both equations look like y =
2x-3y=21 -> -3y= -2x+21 -> y = (-2x+21)/-3 -> y = 2/3x - 7
-6x + 2y = 7 -> 2y = 6x + 7 -> y = 3x + 7/2
now make the equations equal to each other (since they both equal y)
get x
2/3x - 7 = 3x + 7/2
-7 -7/2 = 3x - 2/3x
-14/2 -7/2 = 9/3x - 2/3x
-21/2 = 7/3x
(3/7) -21/2 = x
x = (3/7) -21/2
x = - 63/14
x = - 9/2
put it back in an equation to get y
y = 3x + 7/2
y = 3(-9/2) + 7/2
y = -27/2 + 7/2
y = -20/2
y = - 10

If this question is as simple as it seems all you would have to do is subtract. If he is down 96 feet then goes up 49 feet you would do 96-49.
The answer is 47 feet.

Answer:
Chad had 15 dollars left for gift C.
Step-by-step explanation:
Given:
Chad had total amount = 30 dollars.
Amount spend on gift A = 9 dollars.
Amount spend on gift B = 6 dollars.
To Find:
Amount Left for gift C = ?
Solution:
Total Amount = 30 dollars.
Total number of gifts = 3 i .e Gift A, Gift B , Gift C.
Total amount spend for Gift A and Gift B = Amount spend on gift A + Amount spend on gift B
∴ Total amount spend for Gift A and Gift B = 9 + 6
∴ Total amount spend for Gift A and Gift B = 15 dollars.
Now,
Amount Left for Gift C = Total Amount - Total amount spend for Gift A and Gift B.
∴ Amount Left for Gift C = 30 - 15
∴ Amount Left for Gift C = 15 dollars
The degree of a polynomial is the largest exponent on the variable.
For the given problem there is only one term with an exponent: 5x^2.
The exponent is 2, so the degree would be 2.
