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
10% of 90 is 9. You can try cross multiplying.

Step-by-step explanation:
Reflection <em>is when we flip a figure over.
</em>
Translation <em>is when we slide a figure in any direction.
</em>
Rotation <em>is when we rotate a figure a certain degree around a point.
</em>
Dilation <em>is when we enlarge or reduce a figure.</em>
