What is the y-intercept of the function f(x) = –4 • 2x? A. (0, –4) B. (0, –8) C. (0, 4) D. (0, 2)
mr Goodwill [35]
_C because multiply 2X times f(x) Kansas X out to make it zero Sony multiply -4 times X it will leave you with a positive four instead since X times X

The fuel efficiency for a 2007 passenger car was 31.2 mi/gal. For the same model of car, the fuel efficiency increased to 35.6 m
Ierofanga [76]

We have been given that fuel efficiency for a 2007 passenger car was 31.2 mi/gal and the same model of car, the fuel efficiency increased to 35.6 mi/gal in 2012. Also, the gas tank for this car holds 16 gallons of gas.

We need to write a function and graph a linear function that models the distance that each car can travel for a given amount of gas up to one tankful.

Let represent the functions as d_{1}(x) and d_{2}(x)  where d_{1} and d_{2} represent the distances traveled by car in years 2007 and 2012 and x represents the number of gallons. Therefore, we can express the required functions as:

d_{1}(x)=31.2x \text{ and } d_{2}(x) = 35.6x

Domain of both these functions are [0,16] and ranges are [0,499.2] and [0,569.6] respectively for years 2007 and 2012.

The difference function will be:

f(x)=35.6x-31.2x\\&#10;f(x)=4.2x

f(16)=4.2*16=67.2

Domain of this function is [0,16] and range is [0,67.2].

The graphs are shown below.

Find the measure of the indicated angle that makes lines u and v parallel.
bulgar [2K]

Answer:

1. 135°

2. 114°

3. 118°

4. 81°

Step-by-step explanation:

Let "x" represent the measure of the indicated angle in each problem.

1. x = 135° (corresponding angles theorem)

2. x = 180° - 66° (same-side interior angles theorem)

x = 114°

3. x = 118° (alternate interior angles theorem)

4. x = 81° (alternate exterior angles theorem)
