Answer:y = 160
Step-by-step explanation:
The given equation is expressed as
-80 + y = 80
It is a linear equation with only one variable. The variable is y. The constants on the left hand side of the equation and the right hand side of the equation are - 80 and 80 respectively. To determine the value of the variable, y, we would eliminate the constant on the left hand side of the equation by adding 80 to the left hand side of the equation and the right hand side of the equation. It becomes
-80 + 80 + y = 80 + 80
0 + y = 160
y = 160
Answer:
1. (4, 3) and (8, 6)
2. Yes. The line shows a direct proportion. y = 0.75x
Try (20, 15) in the equation.
15 = 0.75(20)
15 = 15
Point (20, 15) works in the equation, so point (20, 15) is on the line.
3.
Let x = 100.
y = 0.75x
y = 0.75 × 100
y = 75
Since x = 100 gives y = 75, point (100, 75) is on the line.
4.
Let x = 90
y = 0.75x
y = 0.75 × 90
y = 67.5
For x = 90, y must be 67.5. Since this point is (90, 68), it is not on the line.
34,560 cubic inches I think,
2ft= 24in
4ft= 48in
30in x 24in x 48in = 34,560
Answer:
(-1,-5)
Step-by-step explanation:
To understand where this point was before the transformation you must first understand the transformation itself. Shifting left is a horizontal translation, this means that it will affect the x-coordinate. The x-coordinate is the first digit in the pair. Therefore, in the case of (3,5), 3 would be the x-coordinate. Additionally, moving left is moving towards the negative, so it is the same as subtracting. Thus, to find where you started, work backward. Do this by adding 4 to the x-coordinate. This means the beginning coordinate was (-1,-5).
