What is the change in temperature from 15 degrees to -9 degrees? -6, 6, -24, 25
dalvyx [7]

Answer:

24 degrees

Step-by-step explanation:

The distance from 15 degrees to 0 degrees is 15, and the distance from 0 degrees to -9 degrees is 9, so then the total distance from 15 degrees to -9 degrees is (15+9 degrees) which adds up to be 24 degrees

Write an equation parallel to y=3x−1 and goes through the point (-2, -13)
solong [7]

Answer:

y=3x-7

Step-by-step explanation:

we use the equation of the line:

y=mx+b

if the line is parallel, then the slope(m) of the line stays the same:

y=3x+b

we then substitute the ordered pair into the equation and solve for b:

-13 = 3(-2)+b

-13 = -6+b

-13+6 = b

-7 = b

now we substitute the b value into the original equation and the answer:

y=3x-7

Hope this helps :)
