Answer: y=4, x=-2
Step-by-step explanation:
line r must have the equation y=4 to go through point (-2,4)
line s must have the equation x=-2 to go through point (-2,4)
Answer:
63 cm
Step-by-step explanation:
piece 1: x
piece 2: x - 18
First you would subtract 2x - 18 = 108
Second you would add 108 + 18 = 2x
Third you would divide 126 divided by 2x = 63
So that would mean x = 63
The answer is 133 dollars cuz 5580-3186 is 2394 and 2394 divided by 18 is 133
Okay, so first divide 336 / 12 to find out how many miles are driven on each gallon. 336 / 12 = 28 So the car travels 28 miles per gallon (mpg).
Then, divide 1,344 / 28 1,344 / 28 = 48
And there's your answer! D) 48 gallons
9514 1404 393
Answer:
(-5,1)
Step-by-step explanation:
To eliminate x, multiply the first equation by 3 and add 2 times the second equation.
3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)
-6x +21y +6x -8y = 51 -38
13y = 13
y = 1 . . . . . matches the third answer choice
(x, y) = (-5, 1)
