- The sum of 5 and and unknown number is multiplied by 3
- 3 multiplies the sum of 5 and an unknown number.
Step-by-step explanation:
D, because by using this equation you will find that he earned $200 by doing yard work. Also, 3/5 of $200 is $120, so it should be correct.
The equations in slope-intercept form is 5y = x -10, y = 7x-4, y = 8x + 9
<h3>What is slope?</h3>
Slope is the ratio of the change in the y-coordinate to the x coordinate.
Analysis:
The equation in slope-intercept form is y = mx + c
where m is slope, c is y intercept
The equation with slope m = 1/5 and intercept c = -2
is y = 1/5x - 2, 5y = x - 10
The equation with slope m = 7 and c = -4
y = 7x - 4
The equation with slope m = 8 and intercept c = 9
y = 8x + 9

27+15 is 2 so anything that is equal to 42 is equivalent to 27 +15
Answer: 2(−x+y=−2)
2(−x+y=−2)
1(2x−3y=4)
Becomes:
−2x+2y=−4
2x−3y=4
Add these equations to eliminate x:
−y=0
Then solve−y=0for y:
−y=0
−y/-1 = 0/-1 (Divide both sides by -1)
y=0
Step-by-step explanation:
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+y=−2
Substitute 0 for y in −x+y=−2:
−x+0=−2
−x=−2(Simplify both sides of the equation)
−x/-1 = -2/-2 (Divide both sides by -1)
x=2
Answer:
x=2 and y=0
