x = [-inf , 3[
#
C (3,1)
There is the answer and also a check to make sure hope this helps
Answer:
B is correct
Step-by-step explanation:
The person is mentioned is Phil. His amount of money and number of miles are proportionally related (Clark's amount of money and number of miles are not proportionally related due to initial donation)
For Phil, y = ax is his model.
Look into the graph, we can see there is a point where y = 30 and x = 4.
Then rate = 30/4 = 7.5
Answer:
<em>10 feet</em>
Step-by-step explanation:
here's the reason ; -
let's take the missing side be x
we know, the one side of a triangle should always be greater than the difference between the other two sides, so ,
=》x > 7-4
=》x > 3
and the measure of a side should always be less than the some of the other two sides, hence
=》7 + 4 > x
=》11 > x
now, we have : -
11 > x > 3
value of x should be more than 3 and less than 11 , hence 2 ft , 3 ft and 12 ft can't be the measure of third side,
so, we got our third side as 10 ft
