You can use proportions in all of these as I explained in another one of your questions. I'll post the answers if you still want them.
Answer:
−x+−7
Step-by-step explanation:
Let's simplify step-by-step.
4x−6−(5x+1)
Distribute the Negative Sign:
=4x−6+−1(5x+1)
=4x+−6+−1(5x)+(−1)(1)
=4x+−6+−5x+−1
Combine Like Terms:
=4x+−6+−5x+−1
=(4x+−5x)+(−6+−1)
=−x+−7
Answer:
The perpendicular slope would be -1/5.
Step-by-step explanation:
This is because we can locate the slope of the original line as 5 (the number just outside of the x-coordinate parenthesis.
Then we know that perpendicular lines have opposite and reciprocal slopes. So we take the 5 and change the sign (-5), then we flip it (-1/5).
≈120in
The equation for circumstance is 2πr and one tire is 62.83 so two tiers would be 125.66 or ≈ 120
