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.

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
