Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2
Mark as brainliest please
D the answer is 34.5 so it should be closer to 35
No. It's ANY equation that when you put it on a graph, the graph is a straight line.
That almost always means
Y = Ax + B or Ax + By = C
with A, B, and C, being <u><em>any </em></u>numbers.
Another thing it means is that the x and the y are never squared or any other power ... only the 1st power ... and they're never in a denominator of a fraction.
