What is the slope of the line represented by y = 5x - 7?​
Ghella [55]
The slope of the line is 5/1 because the number by the x is always your slope and it is always to be announced as a fraction so you add 1 as the denominator if there isn’t already a denominator.

hammer [34]

Answer:

A. The lines stay parallel

Step-by-step explanation:

Rigid transformations do not change angle or line relationships. When the parallel lines are rotated they stay parallel. Reflecting them will keep them parallel. If this were not true, then figured with parallel lines like rectangles and squares would change shape when reflected.

A $450 TV is discounted 10%, and then another 10% a week later. Explain why taking 20% off the original price will not help you
ExtremeBDS [4]

Answer:

Because the price did not stay the same when they discounted it by 10% percent before.

Step-by-step explanation:

10% percent of 450 is 45 so Subtracting that from 450 would give you,405.

They deducted another 10% percent a week later 10 percent of 405 would be 40.5 so you would subtract that from 405 which would make it 364.5

If you took 20% off originally then 20% of 450 is 90 so subtracting that would make 450 into 360 which is different from 364.5
