Answer:
(a) 0.05 minutes per calorie burned
(b) Slope = 20
Step-by-step explanation:
(a) If 200 calories are burned in 10 minutes...then what about 1 calorie
; 1/200 × 10 = 0.05 minutes
(b) Slope of the graph...;just take any two points on the graph...which are (10;200) and (20;400)
Slope = (400 - 200) ÷ (20 - 10)
;Slope = 200 ÷ 10
;Slope = 20
Website A:
c = 10 + 0.25 s
where c is the cost and s is the number of songs.
Website B:
c = 0.75 s
The equation ( answer ):
10 + 0.25 s = 0.75 s
We can solve this equation:
10 = 0.5 s
s = 10 : 0.5
s = 20 ( Marvin would have to buy 20 songs to to make the costs equal )

Answer:
A. 24.5
B. 29.6
Step-by-step explanation:
A.
19 - 13.5 = 5.5
30 - 5.5 = 24.5
24.5 - 5.5 = 19
24.5
B.
43.8 - 36.7 = 7.1
36.7 - 7.1 = 29.6
29.6 - 7.1 = 22.5
29.6
Answer:
Lines 2 and 3 are parallel with slope (-2/3) and different y intercepts, and both are perpendicular to line 1 (-1) / (3/2) = (-2/3)
Step-by-step explanation:
Parallel lines have the same slope
Perpendicular lines have negative reciprocal slopes
line 1: 6x - 4y = 2
line 1: 4y = 6x - 2
line 1: y = (3/2)x - 0.5
line 2: y = (-2/3)x - 6
line 3:3y = -2x + 4
line 3: y = (-2/3)x + 4/3
