Answer: Choice C)

y < (-1/5)x + 1

The boundary line is y = (-1/5)x+1 as it goes through the points shown. The boundary line is dashed or dotted, meaning that points on this boundary line are not in the solution set. So we will not have an "or equal to" as part of the inequality sign. More specifically, the inequality sign is "less than" because we shade below the boundary line. So that's how we end up with y < (-1/5)x+1.

Answer:

A. 40.18

B. 42.80

B. The sale price of a shirt is 25.68. The original price as reduced by 3/5. The original price is equal to 25.68 = 3/5x. Solve for x by multiplying by the reciprocal. 25.68 ( 5/3) = x. 42.8 = x.

A television weighs 50 pounds and a microwave
Ilia_Sergeevich [38]

Answer:

Step-50*t + 30*m = 1500,   (1)   (pounds)

4*t +  3*m = 138.    (2)   (cubic feet)

From (2), express 3m = 138 - 4t, and substitute it into (1). You will get

50t + 10*(138-4t) = 1500,  or

10t = 1500 - 1380  --->  10t = 1120  --->  t = 112 TVs.

From this point, find the number of microwaves on your own.
