Which of the following points lie in the solution set to the following system of inequalities?
y > −3x + 3
y > x + 2

a
(2, −5)

b
(−2, 5)

c
(2, 5)

d
(−2, −5)

C

Step-by-step explanation:

5 > (-3)(2) + 3

5 > (-6) + 3

5 > (-3) is correct.

5 > (2) + 2

5 > 4 is correct.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
