Answer:
A,shift the graph of y =x2 right 15 units
Step-by-step explanation:
The new equation is subtracting 15 from the value of x.
When you subtract a number from x, the graph moves to the right by the number you subtract.
x-15, shifts the graph right 15 units.
The answer is: Shift the graph of y = x2 right 15 units.
∠E and ∠F are complementary. The measure of ∠E is 54° more than the measure of ∠F. Find the measure of each angle.
The angles are 18° and 72° respectively.
Since, we are told that they are complementary angles, that means that their sum will be equal to 90°
Therefore E + F = 90°
Based on the question, E = F + 54°. Therefore, E + F = 90°.
F + 54° + F = 90°
Collect like terms
2F = 90 - 54°
2F = 36°
F = 36°/2 = 18°
The value of F is 18°
Therefore, E = F + 54° = 18° + 54° ,= 72°
The angles are 18° and 72°.

The measure of angle E is 72 degrees and the measure of angle F is 18 degrees.
Explanation:Let's represent the measure of angle E as x and the measure of angle F as y. Since the angles are complementary, we know that x + y = 90. We also know that x = y + 54. By substituting the value of x into the first equation, we get (y + 54) + y = 90, which simplifies to 2y + 54 = 90. Solving for y, we find that y = 18. Substituting this value back into the equation for x, we get x = 18 + 54 = 72. Therefore, the measure of angle E is 72 degrees and the measure of angle F is 18 degrees.

-8-n = -3(2n - 4)
Please help
Answer:
n=-2n-12
Step-by-step explanation:
Distribute the -3 to 2n-4, which equals -6n+12. Putting your whole equation back together, you will have -8-n=-6n+12. If you add 8n over to the other side, your equation becomes -n=2n+12. Now all you have to do here is divide the negative from -1 thats in front of n from 2n+12, making your answer n=-2n-12.
To solve the linear equation -8 - n = -3(2n - 4), we distribute, combine like terms, and isolate the variable to find that n = 4.
The equation presented, -8 - n = -3(2n - 4), is a linear equation where the goal is to solve for the variable n. We start by simplifying and rearranging the equation to isolate n on one side. To solve the equation:
Distribute the -3 through the parentheses on the right side: -8 - n = -6n + 12.
Move all terms involving n to one side by adding 6n to both sides: -8 + 6n - n = 12.
Combine like terms: -8 + 5n = 12.
Next, add 8 to both sides to isolate the term with n: 5n = 20.
Finally, divide both sides by 5 to solve for n: n = 4.

Mike works two part time jobs while going to college. He works 8 and half hours a week at the ice-cream store for $10.55 per hour and 7 hours a week at the movie theater for 13.85 per hour. Work each of the following problems in decimal form. 1. How much does Mike earn a week before taxes are taken out of his paycheck? 2. If 22 percent of Mike’s paycheck is withheld for taxes, how much money is left for Mike? 3. At which Job does Mike earn the most before taxes, how much more? 4. If Mike spends $50 a week on entertainment, what percent of Mike’s paycheck is left after he pays taxes? In decimal form.
Answer:
Step-by-step explanation:
So 10.55$ for an hour at the ice-cream store, and he works 8 hours.
So 8 * 10.55$ because he earns 10.55$ eight times, since he works 8 hours;
then, you would get $84.40 for a week at the ice-cream store.
Now he earns 13.85$ per hour at the movie theater, for a total of 7 hours.
Again, 13.85$ * 7 since he earns 13.85$ 7 times (7 hours); he gets $96.95 for a week at the movie theater.
1. so we want to know how much does mike earn a week, which basically means how much money did he earn in total during the week working at two jobs?
so you just add what you calculated, you get $181.35 in total.
2. So we want to know how much he has left after 22 percent of the total amount of money that he earned is taken away, due to taxes.
So we want to know how much is 22 percent of the total, so $181.35 * 22% = $39.89
So now we know that $39.89 is 22 percent of the total amount ($181.35), and we know that it is taken away from us, so we subtract $39.89 from $181.35, and you would get $141.46.
So, $141.46 is the amount of money left for Mike after paying his taxes.
3. So we want to know which jobs pays him more before paying the taxes. According to the first question, he earns $84.40 a week at the ice cream store, and $96.95 a week at the movie theater. So, obviously the movie theater pays him more.
It has two questions in one, and the second question asks how much more does the higher paying job pays than the lower paying one. So they're asking what is the difference between the two prices?
So we need to subtract $96.95 (the higher paying one) - $84.40 (the lower paying one), and you would get $12.55.
So, the movie theater pays Mike $12.55 more dollars than the ice cream store.

2. Choose the expression that represents a quadratic expression.
12x4 − 2x3 + 5x2 − 9x − 6
2x3 + 5x2 − 9x − 6
12x2 + 8x − 1
−8x − 1
Answer:
Part 1) Is a cubic expression
Part 2) The quadratic expression is 12x² + 8x − 1
Step-by-step explanation:
Part 1) Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression
Part 2) Choose the expression that represents a quadratic expression
we know that
If the expression is a quadratic equation , then the highest exponent of the variable is 2
therefore
The quadratic expression is 12x² + 8x − 1
Answer:
1. Cubic expression
2. [tex]12x^2+8x-1[/tex]
Step-by-step explanation:
1. We have the expression [tex]5x^3+2x-3[/tex] and we have to classify it.
A quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].
We can see that the first term is squared. And in the expression that we have to classify the first term is raised to the cubic, then it isn't a quadratic expression.
A linear expression has the form [tex]ax+b[/tex].
We can see that it only has two terms and the first term has exponent 1. The expression [tex]5x^3+2x-3[/tex] has 3 terms and the first term has exponent 2 then it isn't a linear expression.
A cubic expression has the form[tex]ax^3+bx^2+cx+d[/tex].
We can see that the first term is raised to the cubic. And [tex]5x^3+2x-3[/tex] is raised to the cubic.
We can rewrite it: [tex]5x^3+2x-3=5x^3+0x^2+2x-3[/tex]
[tex]a=5\\b=0\\c=2\\d=-3[/tex]
The expression [tex]5x^3+2x-3[/tex] agrees with the definition of a cubic expression. Then it's a cubic expression.
An Exponential expression has the form [tex]y=ab^x, a>0[/tex]
2. We said that a quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].
Then the expression that agrees with the definition is [tex]12x^2+8x-1,a\neq 0[/tex]
With,
[tex]a=12\\b=8\\c=1[/tex]

Answer:
The correct option is the first one. An animal skull
Step-by-step explanation:
The correct option is the first one. An animal skull
The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon.
The age detection of the ancient objects are very tough,due to no records are available about the objects.
That's why scientists use carbon-14 dating process.
In this picture, the only object that contains organic material is the animal skull, thus it is the only one that can be dated with this method.
Answer:
The correct option is animal skull
Step-by-step explanation:
Carbon-14 dating is a method for determining the age of an object containing organic material by utilising the properties of a radioactive isotope of carbon. As we have no records of the object, it's become very difficult to detect the age of an object . In such a situation, carbon-14 dating process helps .
In the given picture, animal skull is the only object that contains organic material , so it is the only object for which geologist would use carbon-14 dating to determine age.
Therefore, the correct option is animal scull ( first one )

If the music store sold 12 trumoets and 19 clarinets last month and clariners sell for $139.95 and the store made $4,578.45. The price of a trumpet is $159.95.
What is the price?Let's denote the price of a trumpet as "t" dollars.
The revenue from trumpet sales would be 12 times the price of a trumpet (12t) and the revenue from clarinet sales would be 19 times the price of a clarinet ($139.95):
Revenue from trumpets + Revenue from clarinets = Total revenue
12t + 19 * $139.95 = $4578.45
Now solve for the price of a trumpet (t):
12t + 19 * $139.95 = $4578.45
12t + $2659.05 = $4578.45
12t = $4578.45 - $2659.05
12t = $1919.4
t = $1919.4 / 12
t ≈ $159.95
Therefore the price of a trumpet is $159.95.
