Will mark brainliest! solve the system. a) infinite solutions b) (8, −4) c) (12, 3) d) no solution

Using y = mx + b

8y = 4x - 16  ⇒   y = - 2

-x = -2y - 4  ⇒  2y - x = - 4   ⇒   2y = x - 4   ⇒   y = - 2

Since the equations have the same slope () and y-intercepts (-2), then they are the same line.  Thus, they intersect at every point so have infinite solutions.

A

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
