It is not proportional

Answer:

It is not proportional

Step-by-step explanation:

    To figure out if something is proportional they have to equal the same thing.

   As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.

    Now we come to the 0.08 and the 0.8.

     They are not the same thing the 0.08 has an extra 0.

So this is not proportional

(-2,-4) (2,4) what is the answer in slope intercept form
Morgarella [4.7K]

Answer:

y = 2x

Step-by-step explanation:

We can find the slope

m = (y2-y1)/ (x2-x1)

    = (4--4)/(2--2)

     = (4+4)/(2+2)

   = (8/4)

   = 2

We can use the point slope form of the equation

y-y1 = m(x-x1)

y--4 = 2(x--2)

y+4 = 2(x+2)

Distribute the 2

y+4 = 2x+4

Subtract 4 from each side

y+4-4 = 2x+4-4

y = 2x

y+2 = 2x+4

A car is traveling up a steep ramp to a parking garage.the ramp is 445 feet long and rises a vertical distance of 80 feet. What
Alecsey [184]
With the information provided in the problem, we can create a right triangle with the ramp as its hypotenuse, and  the vertical rise as its opposite side from its angle of elevation.
Let E be the angle of elevation from the car to the end of the ramp. We now know that the hypotenuse of our triangle measures 445 feet, and the opposite side measures 80 feet, so we need a trig function that relates our angle of elevation with the hypotenuse and the opposite side. That function is sine:
sine(E)= \frac{80}{445}
E=arcsine( \frac{80}{445} )
E=10.36

We can conclude that the angle of elevation from the car to the end of the ramp is 10.36°.
