Work Shown:

You could expand terms out and simplify, but I think it's more handy to leave it in this form so you can easily spot the center and radius from a glance.
Answer:
B, C
Step-by-step explanation:
Since y=0, you are looking for equations such that 10 times the coefficient of x is the constant in the equation.
a) 5·10 ≠ 15
b) 2·10 = 20 . . . . select this one
c) 10 = 10 . . . . select this one
d) 3·10 ≠ 13
e) 4·10 ≠ 20
f) 6·10 ≠ 50
Answer:
A
Step-by-step explanation:
As sublet means
Verb:
/səbˈlet/
lease (a property) to a subtenant.
Noun:/ˈsəblet/
a lease of a property by a tenant to a subtenant; a sublease.
B. would make no sense as you would normally be able to do that anyway
C. This would be stated in the rules.
Answer:
It would take 50 minutes
Step-by-step explanation:
<u>Distance, velocity and time</u>
The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by

We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation

The given time is expressed in minutes, we need to convert it to hours. 40 minutes is
. The distance is

If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as


I think the answer is C good luck
