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:
y=3x+2

Answer:
So the expression in standard form will be 
Step-by-step explanation:
We have given expression 
We have to write this expression in standard form
For writing in standard form first we have to multiply the expression
So after multiplication number 
So the expression in standard form will be
Answer:
Area: 1,200 square centimeters. Perimeter: 140 centimeters.
Step-by-step explanation:
Since you have to multiply the length and width in order to find the area, multiply 30 and 40 together and you can find 1,200. Next, to find the perimeter you have to add all the lengths of the rectangular swimming pool, which will result in 140 centimeters.
