Using linear function concepts, the y-intercept of AB is of 11.2.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Given two points of a line, the slope is given by <u>change in y divided by change in x,</u> hence, for A(8,0) and B(3,7):
m = (7 - 0)/(3 - 8) = -7/5 = -1.4.
Then:
y = -1.4x + b.
When x = 8, y = 0, hence we use it to find the y-intercept b as follows:
0 = -1.4(8) + b
b = 11.2.
The y-intercept is of 11.2.

<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>
Answer:
See Explanation
Step-by-step explanation:
Given
A linear equation is represented as:
Where
and
c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5
<em>60 miles traveled</em>
Solving (b): s = 36
Collect like terms
Solve for r
<em>42 gallons used</em>
Answer:
x = -4
Step-by-step explanation:
–2x + 1 – (–7x + 3) = –4 + 3(x – 2)
-2x + 1 + 7x - 3 = -4 + 3x - 6
-2x + 7x - 3x = -4 - 6 - 1 + 3
2x = -8
x = -8/2
x = -4
Answer:
1/5, 1/2, 3/4
Step-by-step explanation:
I just now this already from experience, but you could covert all of the fractions into a common denominator. For example use 20.
1/5 = 4/20
1/2 = 10/20
3/4 = 15/20
Then you just need to look at the numerators which 4,10,15 would be the order. And then make sure to convert to the original fractions making the final order be 1/5, 1/2, 3/4.
