Answer:
D
Step-by-step explanation:
when factoring, the two numbers that you get after you factor are also called solutions, or x intercepts. from this, we know that since the line crosses at positive 1 and positive 9, the answer must be -1 and -9 as you flip the sign after factoring to get the real answer
(ps you can also just plug in all of the answer choices to desmos and see which one matches your graph)

Step-by-step explanation:
1 revolution is equivalent to the circumference of the wheel
1 revolution = πd ( d is the diameter )
= 70π cm
50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )
Yes, this answer is correct.
Answer:
the answer is 9.5 (B)
Step-by-step explanation:
A)
y= total charges
x=number of mattresses
Company A: y=$30x+13 Company B: y=$28x+15
B)
plug x=4 into both equations to get
A: y=30(4)+13=$133
B: y=28(4)+15=$127
Company B charges less because 127<133
C)
Plug in 7 for x
A: y=30(7)+13=$223
B: y=28(7)+15=$211
A-B=223-211
=$12 Saved
