Answer:
A. 9y + 3 = 0
Step-by-step explanation:
To know if a function is linear without graphing it, check if the function is a polynomial of the first degree, because linear functions are polynomials of the first degree. This means that the power of the x-value should be equal to 1.
The only function without this trait is 9y + 3 = 0, so that is our nonlinear function.

Gabrielle and Rob each earn $22 an hour, and each works 40 hours this week. Rob spends 1/2 of his earnings this week on bills and then buys a video game for $25. 75. How much of his earnings fro
The amount spent is an illustration of subtraction and proportions
The amount left in his earnings is $414.25
How to determine the amount left in his earnings?The given parameters are:
Rate = $22 per hour
Time = 40 hours
So, the total earnings is:
Total = $22 * 40
Evaluate
Total = $880
He spent half on bills.
So, we have:
Bills = 0.5 * $880
Bills = $440
He buys a video game for $25.75
So, the amount left is
Amount left = $880 - $440 - $25.75
Amount left = $414.25
Hence, the amount left in his earnings is $414.25

Step-by-step explanation:
the line from the vertex to the base is a perpendicular bisector.

A town has a population of 72,700 and grows at a rate of 3.5% every year. Which equation represents the town’s population after 4 years?
Answer:
for 4 years: [tex]72,700 + 1.035^4(72,700)[/tex]
For n years: [tex]72,700 + 1.035^n(72,700)[/tex]
Step-by-step explanation:
Since each year the growth rate is 3.5 of the last year, n will represent the number of years.
[tex]72,700 + 1.035^n(72,700)[/tex]
Therefore since n is 4, the equation will be:
[tex]72,700 + 1.035^4(72,700) =72,700 + 1.15(72,700)[/tex]
Therefore this equation represents the town after four years.

% compounded continuously. After 20 years, how much more money would Lincoln have in his account than Eli, to the nearest dollar?
Using compound interest and continuous compounding, it is found that Lincoln would have $15,856 more in his account than Eli.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.Hence, for Lincoln, we have that the parameters are as follows:
P = 49000, r = 0.06125, n = 365, t = 20.
Hence the amount will be of:
[tex]A_L(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A_L(20) = 49000\left(1 + \frac{0.06125}{365}\right)^{365 \times 20}[/tex]
[tex]A_L(20) = 166787[/tex]
What is continuous compounding?The amount is given by:
[tex]A(t) = Pe^{rt}[/tex]
For Eli, we have that r = 0.05625, hence the amount will be given by:
[tex]A(t) = Pe^{rt}[/tex]
[tex]A_E(20) = 49000e^{0.05625 \times 20} = 150931[/tex]
What is the difference?It is given by:
[tex]D = A_L(20) - A_E(20) = 166787 - 150931 = 15856[/tex]
Lincoln would have $15,856 more in his account than Eli.

The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.

Solving for the future values of the credit card balances:
1260(1 + 0.12/12)^24
= 1599.8656571502122308900(1 + 0.18/12)^24
= 1286.55253073612259711290(1 + 0.09/12)^24

Solving for the annuity A (monthly payments for each account):
1599.87 = A [(((1 + 0.12/12)^24) - 1) / (0.12/12)] A = 59.31
1286.55 = A [(((1 + 0.18/12)^24) - 1) / (0.18/12)]A = 44.93

x = 66
The measure of the indicated angle is 66 degree.
What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 66 degree.
