47.64/19.85=2.4
2.4*5=12
You bought 12 gallons of gas.
.
Check:
19.85/5=3.97
3.97*12=47.64
On 14 I said slope, it is the same thing as rate of change
Point slop form is y-y1=m(x-x1)
Therefore the answer would be y-3=2/3(x-5)
Answer:
Linear, quadratic, and exponential.
Step-by-step explanation:
In the first table, the y values are decreasing by 3 each step.
In the second table, the y values are perfect square values, making it quadratic.
In the last table, the y values are being multiplied by a factor of 2, making it exponential.
