Kazeer [188]

Answer:

The slope of the given points is $m = \frac{2}{2-c}$

Step-by-step explanation:

If two given points on any line equation are A(a,b) and B(c,d).

The the slope of AB is given as $m = \frac{d - b}{c - a}$

Noe, here the points are given as (c,4) and (2,6)

So, the slope $m = \frac{6-4}{2-c} =\frac{2}{2-c}\\\implies m =\frac{2}{2-c}$

Hence, the slope of the given points is $m = \frac{2}{2-c}$

Mary is planning to provide online math and french language tutoring sessions. The math session will be 45 minutes long, and the

alisha [4.7K]

Answer:

3/4m + 1/2f ≤ 30
f ≤ 30

Step-by-step explanation:

Math session = 45 min = 3/4 hr
French session = 30 min = 1/2 hr
Number of math sessions = m, total math hours = 3/4m
Number of French sessions = f, total French hours = 1/2f

Total hours constraint:

3/4m + 1/2f ≤ 30

Number of session constraint:

f ≤ 30

So the system is:

3/4m + 1/2f ≤ 30
f ≤ 30

I would say the 60 + 20 represents how the shirts cost the same amount. Then I would say the x either represents the cost before tax or how to find the cost of the shirts.

I hope this helps!
Good Luck!
