Answer:
(1, -1)
Step-by-step explanation:
we isolate y in the first equation
2x+y=1
-2x. -2x
y=1-2x
and now we fill y into second equation
4x-2(1-2x)=6
4x-2+4x=6
8x-2=6
+2 +2
8x=8
/8 /8
x=1
and now to find y we insert x
2(1)+y=1
2+y=1
-2. -2
y= -1
hopes this helps
Answer:
pretty sure its the first and 3rd one sorry if im wrong
Step-by-step explanation:
Your answer is B.
She read 5 more than Richard, so D + 5.
& since Ronnie read 2 more than Richard, that’d be 5+2 = 7 to show how much more he read than Yolanda!
C. The graph
The equation y=8x should have a slope of 8. This means that it should go up 8 spaces, every time it moves over by 1. but if you look at the graph you’ll see the slope is 1/8 because it goes up 1 space after moving over 8. If the graph were correct, the x and y values would be swapped.
