Answer:
(1, -2)
Step-by-step explanation:
Subtracting the first equation from the second gives ...
(5x +y) -(3x +y) = (3) -(1)
2x = 2 . . . . . collect terms
x = 1 . . . . . . . divide by 2
Then substituting into the first equation, we have ...
3·1 +y = 1
y = -2 . . . . . . subtract 3
The solution is (x, y) = (1, -2).
Answer:
24
Step-by-step explanation:
12 miles is done in 30 minutes, so if you multiply 12 x 2 (because 30+30=60 and 60 minutes = an hour) you would get the answer of 24.
Basically f(x)=5x means whatever number you plug in will be your x coordinate, and the result will be your y coordinate.
(1,5) (2,10) (3,15) (4,20) and so on. 1,2,3 and 4 are x coordinates plugged into the equation, the y coordinate is whatever 1,2,3 and 4 multiplied by 5 is.
No. For example, if I gave you the equation y= 3x+5, the y-intercept will be at (0,5), eliminating the (0,0).
