Answer:
-$5.27 per day
Step-by-step explanation:
1st. $300
6th. $273.65
19th. $205.14
25th. $173.52
28th. $157.71
Lets use the one that has the least amount of days separated to make it easier
28th and 25th
157.71 - 173.52 = -15.81
count how many days are separated (3)
then divide that to what the amount is
-15.81 / 3 = -$5.27 per day
Answer:
The slope is -3/2
Step-by-step explanation:
<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal.
</u>
Example: Find the line perpendicular to y = 3x
First, you flip the sign which makes 3 into -3
Next, you make the reciprocal which makes -3 into <u>-1/3
</u>
Problem: Find the line perpendicular to y = (2/3)x + 7
First, you flip the sign which makes 2/3 into -2/3
Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>
Answer: The slope is -3/2
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
D is false.
-1 = -(-1)
When you negate the negative on the left, you get a positive 1, not a negative 1.
