Answer:
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
- Negate the slope: 7⇒ -7
- Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7
A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
J) All rational numbers are integers.
Step-by-step explanation:
Rationals numbers can't only be integers. They could also be whole numbers or counting numbers.
I made $120 a week. How much money would I be able to make in 75 weeks?
120 x 75 = 1040
I would make $1040 in 75 weeks.
Hope this was ok enough. :)
Step-by-step explanation:
(3x-2y)³=5³
(3x)³-3(3x)².2y+3.3x.(2y)²-(2y)³=125
27x³-54x²y+36y²x-8y³=125
