Answer:
1. Substitute y = -3x +4 for y in the first equation
2. Combine like terms and isolate x
3. Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1. Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2. Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10 Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
y = -3x +4
y = -3(2) +4
y = -6+4
y=-2
(2,-2)
Answer:
The second band
Step-by-step explanation:
50+20=70
20+25=45
Answer:
x ≤ 90?
Step-by-step explanation:
Yes because if you add forty and thirty that equals seventy plus twenty is 90 which is a right angle
So, the answer to this problem is
x = 9/2 or
x = 4.5.
