I would say A. is the correct answer. Definitely a weird one. Hope this helps!
<h2>
Answer with explanation:</h2>
Let x denotes the number of days and y denotes the total change in gas price ( in dollars).
Given : During the past seven days the price of regular gas is decreased by $0.2 each day.
Rate of decrease =$0.2 per day
Then , Total change in gas price = Rate of decrease x Number of days
i.e.
i.e.
(1)
To find the total change in gas price in 7 days , we put x= 7 in (1) , we get
Hence, the total change in gas price in 7 days = $1.4
Answer:
The answer to your question is 7 and -1/7
Step-by-step explanation:
Data
First line Second line
B (4, 4) A (0, 1)
M (3.5, 0.5) C (7, 0)
Formula
Slope = m = (y2 - y1) / (x2 - x1)
Process
1.- Calculate the slope of the first-line
x1 = 4 y1 = 4
x2 = 3.5 y2 = 0.5
-Substitution
m = (0.5 - 4) / (3.5 - 4)
-Simplification
m = -3.5 / -0.5
-Result
m = 7
2.- Calculate the slope of the second line
x1 = 0 y1 = 1
x2 = 7 y2 = 0
-Substitution
m = (0 - 1) / (7 - 0)
-Simplification
m = -1/7
-Result
m = -1/7
Answer:
The slope would be C) -1/2
Step-by-step explanation:
To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -4)/(0 - 2)
m = 1/-2
m = -1/2
