Tim explained a function in words and paul wrote an equation. tim the amount of money in a savings account increases at a rate of $225 per month. after eight months, the bank account has $4,580 in it. paul y−1,400=56(x+26) whose function has the smaller y-intercept? tim's with a y-intercept of $2,700 paul's with a y-intercept of $2,856 paul's with a y-intercept of $2,800 tim's with a y-intercept of $2,780

Tim's with a y-intercept of $2,780

Step-by-step explanation:

In order to solve this problem we must first find the equation Tim is describing with words. So let's take the first part of the problem:

"The amount of money in a savings account increases at a rate of $225 per month."

this can be written as an equation like this:

where y is the amount of money in the savings account, x is the number of months and is the original ammount of money in the account.

Next, the problem states:

"After eight months, the bank account has $4,580 in it."

so we can use this value to find the initial amount of money in the account, so we plug that value in:

when solving for

we get:

so the equation can now be completed, so we get:

y=225x+2780

whose y-intercept is 2780.

Let's analyze Paul's equation now:

y-1400=56(x+26)

so let's rewrite this equation in slope intercept form. We can do that by solving the equation for y, so we get:

y=56x+1456+1400

which yields:

y=56x+2856

in this case, the y-intercept is 2856.

As you may see, Tim's equation hast the smaller y-intercept which was $2780.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

your answer   is c
