Answer: x = 1 and y = 2
Given:
y = -3x + 5
5x - 4y = -3
Since we are given y, let’s sub it in the second equation.
5x - 4(-3x + 5) = -3
5x + 12x - 20 = -3
17x = 17
x = 1
After finding x, we can now find y.
5(1) - 4y = -3
-4y = -8
y = 2
Checking:
y = -3x + 5
2 = -3(1) + 5
2 = 2
5x - 4y = -3
5(1) - 4(2) = -3
-3 = -3
Answer:
Add 3 over each interval
Step-by-step explanation:
Thirty four times 000 which I am assuming is just zeroes would be 0.
Answer:
zq+u =x
Step-by-step explanation:
z=(x-u)/q
Multiply each side by q
zq = (x-u)/q *q
zq = x-u
Add u to each side
zq+u = x-u+u
zq+u =x
Answer:
2x = 40°
3x = 60°
4x = 80°
Step-by-step explanation:
2x+3x+4x = 180°
9x = 180
x = 20
SO
2x = 2(20) = 40°
3x = 3(20) = 60°
4x = 4(20) = 80°
