You want to simplify or factor it?
Simplify:
7 * χ + 7 * -3 +5χ
=7χ + -21 +5χ
=(7χ+5χ)+-21
=12χ-21
Factor:7(x-3)+5x
12x-21
=3(4x-7)
Answer:
(8, -9), (11, -9)
Step-by-step explanation:
The points (5, 7) and (7, 7) are on a horizontal line in which the y-coordinates of all points are 7. The line has equation y = 7.
For a line to not intersect the line y = 7, it must be parallel to y = 7.
The answer is the pair of points which both have the same y-coordinate, and that y-coordinate is not 7.
From the choices you added to your comments, the only choice with two points with the same y-coordinate is (8, -9) and (11, -9). This is the answer.
Answer: (8, -9), (11, -9)
Answer:
22 miles in 11 hours!
Step-by-step explanation:
We already know a ghost crab can travel 12 miles in 6 hours.
Now, we just need to find the how many miles per hour the crab walks.
We simply divide 12 miles by 6 hours which gives us 2 miles in 1 hour.
That means, we multiply 11 by 2 which gives us 22 miles!
The ghost crab can travel 22 miles in 11 hours. When you find the rate of change by dividing 12 by 6, it gives you 2 m/h. That enables you to find the amount of miles by multiplying 11 hours by two which gives you 22!
