Answer:
7y-4x.
Step-by-step explanation:
I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.
-3(2x- y) + 2y + 2(x+y)
= -6x+3y + 2y+2x+2y
= -6x+2x+3y+2y+2y
= -4x+7y.

Answer:
On the science test the point ( 0 , 424 ) the intercepts is bigger
Step-by-step explanation:
The relation hours spend vs science test score is
y = 6.5*x + 424
And the relation hours spend vs Maths test score is
y = 7.2*x + 34.7
Making x = 0 ( student does not study at all ) we get:
For science score test woul be
y = 0 + 424
In case of maths
y = 0 + 34.7
That mean student without studying will get better score in science.
The point ( 0 , 424) ( science ) represents the interception with y axis
in Maths case such point is ( 0 . 34.7)
