Answer:
The required expression is:
Please check the attached graph too.
Step-by-step explanation:
The slope-intercept form of the linear or line function
where
- m is the rate of change or slope
In our case,
The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.
Thus, the y-intercept b = 3
It is stated that the cost of per kilometer distance = $0.5
Thus, the rate of change or slope m = 0.5
As y represents the cost and x represents the number of kilometers.
so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function
y = mx+b
y = 0.5x + 3
Thus, the required expression is:

Answer:
80
Step-by-step explanation:
the formula to find the volume in a triangular prism that only gives you the base area and the height is:
V = Base area * height
So the question said that the base area is 20 and the height is 4. SO lets put it into the formula:
V = 20 * 4
Now we solve it :
V = 20 * 4
V = 80
So the volume of the prism is 80 square feet.
Hope this helps you!
Answer:
11 franks
Step-by-step explanation:
1) Round 45% to 50% to simplify.
2) Now, we need to find out what 50% of 24 is.
12 is 50% of 24.
3) If 12 is 50%, we can make an educated guess and say...
Jim ate 11 franks for lunch.
Answer:
Step-by-step explanation:
Regular charge- $20
Every hour of service cost- $40
Equation or slope intercept form-
C= 40h+20
Part 1- 20+40(8)=
40 multiplied by 8 320+20 = $340
Part 2- 20+40(10)=
40 multiplied by 10 400+20 = $420
