If I translated correctly into my native language, then you need to write the equation of the straight line.
y=x this is a straight line through the first and third quarters.
1) multiply by 2: y= 2x
2) to raise the function by 3 units, you need to add 3 to it. For example: y=2x to bring it up: y=2x+3
Your friend loans you $550 to buy a PS5. They are going to charge you 3% interest rate. After some time you pay your friend back the $550 plus $33 in interest. How long did it take you to pay your friend back?
Answer:
2 years
Step-by-step explanation:
3% of $550 = 0.03 * $550 = $16.50
3% interest on $550 for 1 year is $16.50
$33/$16.50 = 2
Since 2 * $16.50 = $33, the loan was for 2 years.

Eliza started her savings account with $100. Each month she deposits $25 into her account. Determine the average rate of change in Eliza's account from the 2nd month to the 10th month. Show all work for full credit.
Answer:
25
Step-by-step explanation:
First, lets create a equation for our situation. Let x be the months. We know four our problem that Eliza started her savings account with $100, and each month she deposits $25 into her account. We can use that information to create a model as follows:
25x+100
We want to find the average value of that function from the 2nd month to the 10th month, so its average value in the interval [2,10].
We can conclude that the average rate of change in Eliza's account from the 2nd month to the 10th month is $25.

Which is an equation of the line that passes through the point (0, 4) and is perpendicular to the line whose equation is y = −12x + 3?
Since the line that we need to figure out is perpendicular to the one given, the slope of the line in question is going to be the opposite-reciprocal of the slope of the given line.
Slope of the given line = -12
Slope of the new line = [tex]\frac{1}{12}[/tex]
We will use the point given and the new slope to determine the y-intercept using slope-intercept form.
[tex]4 = \frac{1}{12}(0) + b\\\\4 = 0 + b\\\\4 = b[/tex]
Formula for this line
[tex]y = \frac{1}{12}x + 4[/tex]
We can graph the lines to check our work.
Both lines are perpendicular.

Solve the system of linear equations by substitution. Check your solution.
Answer:
[tex]x = 1.5[/tex]
[tex]y =1[/tex]
Step-by-step explanation:
Given
[tex]4x + 2y = 8[/tex]
[tex]6x - 4y = 5[/tex]
Required
Solve for x and y
[tex]4x + 2y = 8[/tex] --- (1)
[tex]6x - 4y = 5[/tex] --- (2)
Divide equation (1) through by 2
[tex]\frac{1}{2}(4x + 2y) = 8*\frac{1}{2}[/tex]
[tex]2x + y = 4[/tex]
Make y the subject
[tex]y = 4 - 2x[/tex]
Substitute 4 - 2x for y in equation (2)
[tex]6x - 4y = 5[/tex]
[tex]6x - 4(4- 2x) = 5[/tex]
Open bracket
[tex]6x - 16+ 8x = 5[/tex]
Collect Like Terms
[tex]6x + 8x = 5+16[/tex]
[tex]14x = 21[/tex]
Solve for x
[tex]x = \frac{21}{14}[/tex]
[tex]x = 1.5[/tex]
Substitute 1.5 for x in [tex]y = 4 - 2x[/tex]
[tex]y = 4 - 2(1.5)[/tex]
[tex]y = 4 - 3[/tex]
[tex]y =1[/tex]
To check the solution:
Substitute the values of x and y i the equations
[tex]4x + 2y = 8[/tex]
[tex]4 * 1.5 + 2 * 1 = 8[/tex]
[tex]8 = 8[/tex]
[tex]6x - 4y = 5[/tex]
[tex]6 * 1.5 - 4 * 1 = 5[/tex]
[tex]5 = 5[/tex]
Hence, the solution is true
(1 point) Suppose the chance a player will win a single round of a certain gambling game is (supposedly) 25%, independently of other rounds. You play 100 rounds and win only 18 times. This is less than the expected value. Was it just bad luck
Answer:
It was simply a case of bad luck.
Step-by-step explanation:
The predictable win outcome from playing a round of a certain gambling game = 25%
If one plays 100 rounds, the predictable wins should be 25 (100 * 25%)
If the actual wins = 18, which is less than the predictable wins of 25, the actual result is less than the expected value or outcome by 7. This is simply a case of bad luck. Bad luck is defined as an unpredictable outcome that is unfortunate. It is when the predicted (expected) outcomes, 25 wins, are more than the unpredicted (actual observed) outcomes, 18 wins.
Look at the inequality.

TRIANGLES ARE NOT CONGRUENT
Answer:
SAS; side angle side
Step-by-step explanation:
The diagrams indicates that two sides are already congruent:
the sides marked with 3 dashes have the same length
the sides marked with 2 dashes have the same length
These two statements leaves only SAS or Triangles are Not Congruent as the only options.
However, the middle angles are congruent due to the opposite angle law.
The rule states that two angles that are opposite each other when two lines cross have the same degree measure.
Since the middle angle are vertically opposite angles, the only remaining answer is SAS
The elves and reindeer are
getting ready for a meeting with
Santa. 15 of them have arrived
so far. If they have 40 legs
between them, how many elves
are at the meeting and how
many reindeer are at the
meeting?
G
Answer:
10 elves and 5 reindeerStep-by-step explanation:
Let the number of elves be x and reindeer be y, then we have equations:
x + y = 152x + 4y = 40Simplify the second equation and subtract the first one:
x + 2y = 20(x + 2y) - (x + y) = 20 - 15y = 5Then find x:
x = 15 - 5 = 1010 elves and 5 reindeer at the meeting
David is buying a cheese wheel priced at $14 before tax. The store charges 8% sales tax.
What is the total price, including tax, David pays for the cheese wheel?
Answer:
$15.12
Step-by-step explanation:
1. Find the total amount of sales tax. This can be done by multiplying the before tax price by the sales tax percentage.
14 x 8% = 1.12
2. Add the sales tax amount back to the price.
14 + 1.12 = $15.12

Use the cosine ratio or the inverse cosine to solve for x. Round your answer to the nearest tenth.
Answer:
x = 50.8°
Step-by-step explanation:
By applying cosine ratio in the given triangle PQN,
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{PN}{PQ}[/tex]
cos(x) = [tex]\frac{12}{19}[/tex]
x = [tex]\text{cos}^{-1}(\frac{12}{19})[/tex]
x = 50.83°
x ≈ 50.8°

A teacher wants to split 9 crayons between 5 students equally. How many will each student get?
Answer:
1 crayon each, because you can not have 1.8 crayons
Step-by-step explanation:
Out of the total 9 crayons, each student will get 1 crayon.
What is Unitary Method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given is a teacher who wants to split 9 crayons between 5 students equally.
A total of 5 students will have → 9 crayons
Then 1 student will have → 9/5 → 1.8 crayons.
Since crayons cannot be in fractions and the distribution should be equal among all students, therefore, each student will get 1 crayon and the remaining 4 cannot be divided equally among them.
Therefore, out of the total 9 crayons, each student will get 1 crayon.

A homeowner wants to include a semicircular patio at the end of a square sandbox. She knows that the area of the semicircular patio is 25.12 cm. What is the length of the side of the square?
Answer:
8cm
Step-by-step explanation:
First you must know that the diameter of the semi-circular patio is equal to the length of one side of the square
Area of a semi circle = πr²/2
25.12 = πr²
25.12 = 3.14r²/2
r² = 25.12(2)/3.14
r² = 16
r = √16
r = 4
Get the diameter
d = 2r
d =2(4)
d = 8cm
Hence the length of the side of the square is 8cm
