Answer:
The domain is all of the x values. From the graph, all of the x values are greater than or equal to 0 so the answer is x ≥ 0.
Answer:
400 sq. ft.
Step-by-step explanation:
We gotta find the length of a side:
First, we divide 80 by 4, because the perimeter of a square is (4 x side):
80 ft. / 4 = 20 ft.
Second, we doing the normal area of a square equation:
= 400 square ft.
Which leads to out answer of 400 sq. ft.
Eight of the DVD with packing material is 0.19 lb.
1.10+8.5x=2.25+2.5x
Move variables to one side. The easier one would be to move 2.5x. So you subtract 2.5x to both sides.
1.10+6x=2.25
Do the same for the values without the x. The easier one would be to subtract 1.10 from both sides.
6x=1.15
Then divide by 6
1.15/6=0.19
$20 + $12=
$20 per shirt
$12 per tie
