Answer:
85
Step-by-step explanation:
15 times 6 is 90. This is how much money he spends on 6 DVDs if they're all $15. 90 subtracted by 5 (remember - he gets $5 off his entire purchase, not just each individual DVD) would be 85!
Answer:

Step-by-step explanation:
Given


Required
Determine the average rate of change
Average rate is calculated as thus;

<em>In this case; b = 12 and a = 6</em>
Calculating f(12)



Calculating f(6)



Substitute 12 for b and 6 for a in 

Substitute values for f(6) and f(12)



Answer:
The type of quadrilateral is a rectangle
Step-by-step explanation:
we know that
A rectangle is a quadrilateral with four right angles and two pairs of congruent and parallel sides
see the attached figure to better understand the problem



therefore
The type of quadrilateral is a rectangle
True!
4(0) -1 = -1
2(0) +7 = 7
