Answer:
Step-by-step explanation:
Te equation of line is:
y = 3x + 12
Plug x = 0 in the above equation of line, we find:
y = 3*0 + 12
y = 0 + 12
y = 12
y-intercept = (0, 12)
Plug y = 0 in the equation y = 3x + 12
0 = 3x + 12
-3x = 12
x = 12/(-3)
x = - 4
x-intercept = (-4, 0)
Distance between x-intercept and y--intercept
The amount of quarts of water to fill the jar is 10.6875 quarts
To solve this problem effectively, we need to understand the concept of word problems.
<h3>What are word problems in mathematics?</h3>Word problems in mathematics are questions that require a crucial understanding and application of mathematical principles to solve them effectively.
From the parameters given:
Then, the total amount of ounces that fills the water is:
= 114 ounces × 3
= 342 ounces
From the dimensional analysis of measurements:
1 ounce = 0.03125 quarts
Thus, in quarts, 342 ounces will be:
= 10.6875 quarts

Step-by-step explanation:
From the attached photo, we can deduce:
(2,2) as (x1,y1)
(-2,-4) as (x2,y2)
Slope Formula =
Now we can substitute these values into the formula to find the slope.
Slope of line =
A)The formula for the average monthly cellular telephone bill in terms of the year will be A = 80.90(0.914)ⁿ⁻¹
B)The average monthly bill in 1993 willl be $ 61.77
<h3>What is the percentage?</h3>The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The formula for the average monthly cellular telephone bill in terms of the year willl be,
A=P(R/100)ⁿ
A = 80.90(0.914)ⁿ⁻¹
The average monthly bill in 1993 is found as ;
n=4 for 1993
A=P(R/100)ⁿ
A = 80.90(0.914)³⁻¹
A=$ 61.77
Hence the formula for the average monthly cellular telephone bill in terms of the year will be A = 80.90(0.914)ⁿ⁻¹ and the average monthly bill in 1993 willl be $ 61.77.
