Suppose you start with a full tank of gas (17 gallons) in your truck. after driving 4 hours, you now have 3 gallons left. if x is the number of hours you have been driving, then y is the number of gallons left in the tank. at what rate is your truck using gas? state your answer as a reduced fraction. incorrect gallons per hour find an equation of a line in the form y = mx + b that describes the amount of gas in your tank. y =

Part a) The rate is equal to

Part b)

Step-by-step explanation:

step 1

Let

x-----> the number of hours

y----> the number of gallons left in the tank

we know that

For -----> represent the y-intercept

For

Find the rate (slope of the linear equation)

simplify

step 2

Find the equation of the line

the equation of the line in slope intercept form is equal to

we have

substitute

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
