Loan: Ross borrows $5625 to buy a car. He pays back $125 each month. The equation y = 5625 - 125x represents that amount Ross owes y after x months.
A. Find the x and y-intercepts and interpret their meaning in the context of the situation.
The x-intercept is _____. This means that after ____ months, Ross will owe $____. The y-intercept is _____. This means that Ross initially owed $_____.
B. Graph the equation using the intercepts.

Answers

Answer:

Ross initially owed 5625. the y intercept is 0,3500. Part of the answer.

There are x and y-intercepts that would be  5625 and 45 respectively for the given equation.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Ross borrows $5625 to buy a car. He pays back $125 each month which is given in the question.

The equation y = 5625 - 125x represents the amount Ross owes y after x months

⇒ y = 5625 - 125x

To determine the y-intercepts of the equation,

We have to substitute x = 0 in the equation

⇒ y = 5625 - 125(0)

⇒ y = 5625

To determine the x-intercepts of the equation,

We have to substitute y = 0 in the equation

⇒ 0 = 5625 - 125x

⇒ 125x = 5625

⇒ x = 45

Hence, there are x and y-intercepts that would be  5625 and 45 respectively for the given equation.

A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear

Answers

Answer:

A, the function is linear, and the ROC is constant.

Step-by-step explanation:

Answer:

A is true.

Step-by-step explanation:

Rate of change = difference in y / difference in x

= (7-8)/ 10/8) = 1/2

also 11-8/16-10 = 1/2

and 14-11/22-16 = 1/2.

The rate of change is constant.

If a function is defined as C(x) =(.80x, for 0 500 Find the value of C(100), C(255), C(550), C(500), C(O), C(250), C(400) .

Answers

Answer:

80 ; 204 ; undefined ; 400 ; 0 ; 200 ; 320

Step-by-step explanation:

C(x) =(.80x, for 0 500 )

Find the value of :

C(100) = 0.80*(100) = 80

C(255) = 0.80 * 255 = 204

C(550) = undefined

C(500) = 0.80 * 500 = 400

C(O) = 0.80 * 0 = 0

C(250) = 0.80 * 250 = 200

C(400) = 0.80 * 400 = 320

In a large city’s recent mayoral election, 131,506 out of 309,153 registered voters actually turned out to vote. If 20 registered voters are randomly selected, find the probability that 7 of them voted in the mayoral election. Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability.

Answers

The probability that 7 of them voted in the mayoral election using the calculator is 0.1455

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The probability of registered voters actually turned out to vote:

= 131,506/309,153

p = 0.4254

n = 20

From the calculator:

P(X = 7) = 0.14546189

or

P(X = 7) = 0.1455

Thus, the probability that 7 of them voted in the mayoral election using the calculator is 0.1455
