<h3>Answer:  {7, 11, 15, 19}</h3>

Write the values in the order shown. The curly braces indicate a set.

=================================================

Explanation:

The replacement set for the independent variable is {2,4,6,8}

This means we'll plug x = 2, x = 4, x = 6, and x = 8 into the function one at a time to find the corresponding y = f(x) value.

---------

Plug in x = 2 to find that,

f(x) = 2x+3

f(2) = 2*2+3 ... replace every x with 2

f(2) = 4+3

f(2) = 7

If the input is x = 2, then the output is y = 7. Therefore, the '2' in the domain corresponds to '7' in the range.

If you repeat those steps for x = 4, then you should find that f(4) = 11. Do the same thing for x = 6 and it should lead to y = 15. The last value in the range is y = 19 which corresponds to x = 8.

In short, the domain {2,4,6,8} corresponds to the range {7, 11, 15, 19}

Usually with sets, order doesn't matter. However, in this case, the order is important because we need to match the 2 with the 7, the 4 with the 11, etc.

Otrada [13]

The angle measure of ACB is 9 degrees

Answer: Option B

<u>Step-by-step explanation:</u>

To find the solution to the given problem, first we need to look into the point B. It consists two angles and both of them are on a straight angle. So, this means that the sum of angle ABC and CBD is 180 degrees, that is

               \angle A B C+\angle C B D=180^{\circ}

We know that \angle C B D=29^{\circ}. Therefore

               \angle A B C+29^{\circ}=180^{\circ}

               \angle A B C=180^{\circ}-29^{\circ}=151^{\circ}

Now, in the triangle ABC, we know that all three angles must sum 180 degrees,

               \angle C A B+\angle A B C+\angle B C A=180^{\circ}

               20^{\circ}+151^{\circ}+\angle B C A=180^{\circ}

               \angle B C A=180^{\circ}-20^{\circ}-151^{\circ}=9^{\circ}=\angle A C B

Therefore, the angle ACB is 9 degrees.

Which one of the following is not closed under the operation being performed
Sergeu [11.5K]
Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.

A. (14x-2)3(x-2)=14 x^{2} -90x+10. The result is still a polynomial; therefore, answer A is incorrect.

B. \frac{(14x-2)}{3(x-2)} =  \frac{14}{3} with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.

C. (14x-2)+3(x+2)=17x+4. The result is still a polynomial; therefore, answer C is incorrect.

D. (14x-2)+3(x+2)=17x+4. The result is still a polynomial; therefore, answer D is incorrect.

1.Anthony has decided to purchase a $19,000 car. He plans to put 20% down toward the purchase and to finance the rest at a 6.8%
Nikitich [7]
<h2>First step/Equation</h2>

Answer:

 $362.57

Step-by-step explanation:

A suitable calculator or finance app can find the monthly payment for you. This result comes from a TI-84 calculator.

___

The second attachment shows the parameters of the payment function. With 20% down, Anthony is only financing 80% of the price of his car. Of course, there are 12 months in a year, so 4 years worth of payments will be 48 payments. The calculator uses negative values for amounts you pay.

___

No doubt your reference material shows you a formula for computing loan payments. One such is ...

 A = Pr/(1 -(1+r)^-n)

where r is the monthly interest rate, 0.068/12, and n is the number of payments, 48. The principal amount of the loan, P, will be 19,000×0.80. This formula gives the same result as that shown above and below
