Answer:
x=−y−1
Step-by-step explanation:
y=−x−1
Step 1: Flip the equation.
−x−1=y
Step 2: Add 1 to both sides.
−x−1+1=y+1
−x=y+1
Step 3: Divide both sides by -1.
−x
−1
=
y+1
−1
x=−y−1
7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6
Answer:
8. yes
9. no
10. yes
Step-by-step explanation:
8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).
__
9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.
__
10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.
Answer:
A
Step-by-step explanation:
Table A
input is 5 and output is 9
Using the 2 given rules
Increase the input by 4 to get output , then
5 + 4 = 9 ← correct output
Multiply input by 2 and subtract 1 to get output , then
2 × 5 - 1 = 10 - 1 = 9 ← correct output
Table A works for both rules
Answer:
Company A has a greater daily rate
Step-by-step explanation:
Given
Company A
Company B
Required
Determine the company with greater rate
Simplify the expression of company B
In a linear function:
m represents the rates.
This implies that the rate of company B is:
and the rate of company A is
By comparison:
Company A has a greater daily rate
