Point slope formula:
We know that:
m=-13
y1=7
x1=5
Plug those into the equation to get a final answer of:
Answer:
25 +15x
Step-by-step explanation:
so the fee to rent a truck is 25 but for every hour that you have it, you have to pay $15, so x represents the number of hours you have the truck, so if you have the truck for 3 hours, you would say 25+15(3)= $70
The answer to the question
Answer:
Step-by-step explanation:
The sign of a product or quotient cannot be determined by the positive number (t), so we can ignore it. The sign of the expression will be negative if and only if there are an odd number of negative factors.
Here, there are 67 (an odd number) negative factors, so the expression will be negative.
Answer:
<u>1.16 m (approximately)</u>
Step-by-step explanation:
Let x be the width of the path.
Total area = (5+2x)(3+2x) = 39
Expand and simplify
4x²+ 16x+15-39 = 0
4x² + 16x - 24 = 0
Simplify
x² + 4x -6 = 0
Rational factoring does not work, so use quadratic formula
x = +/- sqrt(10) -2
= 1.16 or -5.16 (reject)
= <u>1.16 m (approximately)</u>
