Consider the y-intercept. The equation of your model is y = 8.39x. The y-intercept is zero. Should it be? Explain.

yes, the y-intercept should be 0.

Step-by-step explanation:

The b in this slope-intercept equation is 0, so the y-intercept is 0.

Another way to figure out the y-intercept is to set x to 0; the resulting y-value is the y-intercept:

y = 8.39(0)

y = 0 so the y-intercept is 0.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
