Step-by-step explanation:

Simplify :

x4−6x3+2x−7+7x3−x+5x2+2−x4

Rearranging and collecting the like terms, we get:

=(x4−x4)+(−6x3+7x3)+5x2+(2x−x)+(−7+2)

=(1−1)x4+(−6+7)x3+5x2+(2−1)x+(−7+2)

=(1)x3+5x2+(1)x−7+2

=x3+5x2+x−5

5. A car travels at a speed of 72 miles per hour. Write a direct variation equation for the distance, y, the car will travel in

astraxan [27]

Answer:

y = 72x

324miles

Step-by-step explanation:

Given parameters:

Speed of the car = 72miles/hr

distance = y

time = xhrs

Unknown:

Write a direct variation equation for the distance= ?

Distance covered in 4.5hrs =?

Solution:

A. Write a direct variation equation for the distance;

A direct variation is a linear equation.

It often takes the form y = kx

For this problem;

Distance = speed x time

input the parameters;

y = 72x

The direct variation equation is y = 72x

B. Distance traveled in 4.5hrs

y = 72x

x is the time taken;

So;

y = 72 x 4.5 = 324miles
