Answer:
False.
Step-by-step explanation:
A point on the cordinate plane needs an x-coordinate and a y-coordinate.
The point is (x1, y1) not just x1.
Answer:
Step-by-step explanation:
Red =x Blue = y
1) 4x + 6y = 180
2) x + y = 40
solve for x in eq. 2 and plug into eq. 1
2a) x=40-y
1a) 4(40-y) + 6y = 180
160-4y +6y = 180
2y=20
y=10
plug into eq. 2
x + 10 =40
x=30

Good luck on ur test

Expand the left side:
3x-18 = 10x + 3
Subtract 3x from each side:
-18 = 7x + 3
Subtract 3 from each side:
-21 = 7x
Divide each side by 7 :
<u>-3 = x</u>
Hey how long do I have to complete this?
