Answer:
2 hours
Step-by-step explanation:
30 miles/x hours = 15 miles/1 hour
30 = 15x
x = 2 hours
Given:
The table of values is:
x : -7 -5 -3 -1
y : 5 9 13 17
To find:
Whether the given data is linear and then find the equation.
Solution:
The given data is linear if the slope and rate of change is constant.
Slope formula:

Using the slope formula. we get



Since the rate of change is constant, i.e., 2, therefore the given data is linear.
The slope of a linear equation is 2 and it passes through the point (-7,5). So, the equation of the line is:




Adding 5 on both sides, we get


Therefore, the equation for the given data is
.
450/25= 18
where 450 is $4.50 and 25 is one quarter. there will be 18 quarters.
560-450=110
110/10=11
where 110 is $1.10 and 10 is one dime. there will be 11 dimes.
11+18= 29
where 11 is total number of dimes and 18 is total number of quarters. and 29 is total number of coins
