Answer:
he awnser is c) 22d + 12, Every time 1 day of rental is added , the cost rises $22 which means each day you rent the tractor it will be $22 + the fixed fee ( that you can discover by applying d(22) in one of the equations.
Answer:
Step-by-step explanation:
The given table is
Days Cost to Rent a Truck
1 34
2 56
3 78
4 100
To right a function of this expression, we first have to find the ratio of these values and then use the point-slope form to get the equation which is linear, because the table is showing a linear relation.
[tex]m=\frac{100-34}{4-1}=\frac{66}{3}=22[/tex]
Now, we take one point and the slope to find the linear function
[tex]y-y_{1}=m(x-x_{1})\\y-100=22(x-4)\\y=22x-88+100\\y=22x+12[/tex]
Therefore, the function has to have a ratio of change of 22 and an y-axis interception at y=12. So, the answer is the first choice, where x is d and y is c.
