I would use the website desmos to help you out. But it won't help you forever like when you do quizzes or tests.
Directions:
Make the variable "y" all by itself. It need to be solo. For example for problem 34, negate 3 on each side and you will have "y=1/2(x+2)+3".
From there, plug in numbers into the x variable. (I suggest using common factors of "2" since the number your multiplying is 1/2.
Again using 34,
y=1/2(x+2)+3
y=1/2(2+2)+3
y=1/2(2+2)+3
y=1/2(4)+3
y=2+3
y=5
The coordinates are (2,5). Plot the coordinate.
Repeat the process.

If the 11th term of a geometric sequence is 32 times larger than the 6th term, then what is the common ratio of the sequence?
Answers
Answer:
2
Step-by-step explanation:
Given that:
11th term of a geometric sequence is 32 times larger than the 6th term
The nth term of a geometric sequence is given by:
An = A*r^(n-1)
Where An = the nth term ; r = common ratio and n = term number ; A = first term
The 11th term:
A6 = A*r^(6 - 1) = Ar^5
A11 = 32A6 = 32Ar^5
A11 = Ar^(11 - 1) = Ar^10
Hence,
Ar^10 = 32Ar^5
r^(10 - 5) = 32
r^5 = 2^5
Hence, r = 2

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following is true? A coordinate plane with 12 distinct points plotted which are not connected. The points are 0 comma negative 20, 1 comma negative 10, 2 comma 0, 3 comma 10, 4 comma 20, 5 comma 30, 6 comma 40, 7 comma 50, 8 comma 25, 9 comma 40, 10 comma 55, and 11 comma 70. Group of answer choices The x-intercept represents the shirts he has to sell before making a profit. Benito increases the price after selling 50 shirts. The y-intercept represents the cost of one T-shirt. The domain of the function is {x | x is a real number greater than or equal to 0}.
Answers
Answer:
The correct option is;
The x-intercept represents the shirts he has to sell before making a profit
Step-by-step explanation:
The given data are;
(0, -20), (1, -10), (2, 0), (3, 10), (4, 20), (5, 30), (6, 40), (7, 50), (8, 25), (9, 40), (10, 55), (11, 70)
The data show a linear relationship because successive data point increases by the same amount of 10 for x between 0 and 7 and 15 for x between 8 and 11;
Therefore;
Slope, m of the first linear portion using points (2, 0), and, (4, 20) gives;
m = (20 - 0)/(4 - 2) = 10
The equation of the line is therefore;
y - 20 = 10·(x - 4)
y = 10·x - 40 + 20
y = 10·x - 20
The y-intercept (x = 0) is y = -20
The x-intercept (y = 0) is found as follows;
0 = 10·x - 20
20 = 10·x
10·x = 20
x = 20/10 = 2
Therefore, when x = 2 we have;
Profit = y = 10·x - 20 = 10×2 - 20 = 0
Which can be expressed as, he has to sell more than 2 shirts to make profit
Therefore, the correct option is that the x-intercept represents the shirts he has to sell before making a profit.
Cooper will deposit $1,500 into an account that earns 7% simple interest every year. His sister Trinity will deposit $1,800 into an account that earns 6% simple interest every year. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Which statement about the balances of Cooper's and Trinity's account at the end of 3 years is true?
Answers
Answer:
For Cooper :
Simple interest = $315
The total amount he would have in his account = $1815
For Trinity :
Simple interest = $324
The total amount she would have in her account = $2124
Trinity's interest is higher than Cooper's interest by $9
The total amount of money Trinity would have at the end of 3 years is higher than that of Cooper by $309
Step-by-step explanation:
Simple interest = principal x rate x time
Value = amount deposited + simple interest
For Cooper :
Simple interest = $1,500 x 0.07 x 3 = $315
The total amount he would have in his account = $1,500 + $315 = $1815
For Trinity :
Simple interest = $1800 x 0.06 x 3 = $324
The total amount she would have in her account = $1,800 + $324 = $2124

What is a line segment?A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
If EF = 2x - 8, FG = 4x - 13, and EG = 27.
Point F lies on the line segment EG. Then we have
EG = EF + FG
27 = 2x - 8 + 4x - 13
27 = 6x - 21
6 = 6x
x = 1
Then the value of the variable x will be 1.

What is 5.57575757... as a fraction ?
Answers
Answer:
[tex]\frac{5.57575757}{1}[/tex]
Step-by-step explanation:
Assuming you can't use a calculator:
5.575757... = 5 + 0.575757...
let 0.575757... = x
1) Substitute x for 0.575757...
5.575757... = 5 + x
2) Multiply both sides by 100
100(5.575757...) = 100(5+x)
557.575757... = 500 + 100x
3) Subtract 500 from both sides
57.575757... = 100x
4) 57.575757... can be written as 57 + 0.575757...
57 + 0.575757... = 100x
5) Substitute x for 0.575757...
57 + x = 100x
6) Subtract x from both sides
57 = 99x
7) divide both sides by 99
x = 57/99
8) plug in 57/99 for x in our original equation
5.575757... = 5 + (57/99)
9) simplify
5.575757... = ((5*99)/99) + (57/99)
5.575757... = (495/99) +(57/99)
5.575757... = (495+57)/99
5.575757... = 552/99
5.575757... as a fraction is 552/99
if h(x)=5+c and k(h)=1/x, which expression is equivalent to (k•h)(x) a. (5+x)/x b.1/(5+x) c. 5+(1/x) d. 5+(5+x)

We are given the two functions:
[tex]\displaystyle h(x)=5+x \text{ and } k(x) = \frac{1}{x}[/tex]
And we want to find:
[tex](k\cdot h)(x)[/tex]
Recall that this is equivalent to:
[tex]\displaystye (k\cdot h)(x) = k(x) \cdot h(x)[/tex]
Substitute and simplify:
[tex]\displaystyle \begin{aligned} (k\cdot h)(x) & = \left(\frac{1}{x}\right)(5+x) \\ \\ & = \frac{5+x}{x} \end{aligned}[/tex]
In conclusion, our answer is A.
Answer:
A. (5 + x) / x
Step-by-step explanation:
h(x) = 5 + x
k(h) = 1 / x
express the above to (k*h)(x)
(k*h)(x) = (1 / x) * (5 + x)
= 1/x (5+x)
= 1 * (5 + x)

Step-by-step explanation:
Given
Bisector: QS
[tex]PQS = 5x[/tex]
[tex]RQS = 2x + 6[/tex]
Required
Determine PQR
Since PQR is bisected to PQS and RQS, we have that
[tex]PQS = RQS[/tex]
Substitute expressions for PQS and RQS
[tex]5x = 2x + 6[/tex]
Collect Like Terms
[tex]5x - 2x = 6[/tex]
[tex]3x = 6[/tex]
Divide both sides by 3
[tex]x = 2[/tex]
Solving for PQR;
[tex]PQR = PQS + RQS[/tex]
[tex]PQR = 5x + 2x + 6[/tex]
[tex]PQR = 7x + 6[/tex]

Points A, P, and B are collinear on AB, and PB:AB = 2/7. A is located on the origin (0,0), P is located at (10, -5), and B is located at (x, y). Which axis is closer to B, the x-axis or the y-axis? Justify your answer.
I don't know how to show the work.
Answers
Answer:
The x-axis is closer to B.
Step-by-step explanation:
Since the ratio PB:AB = 2/7 is positive, the line divides internally. So, we use the equation for the coordinates of a point that internally divide a line.
So, x = (mx₂ + nx₁)/(m + n) and y = (my₂ + ny₁)/(m + n)
where PB/AB = 2/7 = n/m. So, n = 2 and m = 7
Also, Point A = (0,0) = (x₁, y₁) and point P = (10, -5) = (x₂, y₂).
Substituting these values into x and y, we have
x = (mx₂ + nx₁)/(m + n)
x = (7(10) + 2(0)₁)/(7 + 2)
x = (70 + 0)/9
x = 70/9
x = 7⁷/₉
y = (my₂ + ny₁)/(m + n)
y = (7(-5) + 2(0)₁)/(7 + 2)
y = (-35 + 0)/9
y = -35/9
y = -3⁸/₉
So, the x and y coordinates of B are 7⁷/₉ and -3⁸/₉ respectively. So, point B is -3⁸/₉ units away from the x-axis and 7⁷/₉ units away from the y-axis. So the x-axis is closer to B.
Which parent functions have no symmetry?

Answer:
Square Root, Greatest Integer
Step-by-step explanation:
Functions can be symmetrical in two ways: They can be symmetrical across a line or symmetrical across a point.
In a Square root function, when reflected across the y-axis, the graph has no symmetry because -x returns a different value when plugged into the function.
For a Greatest Integer function, with [tex]\lfloor x \rfloor[/tex], if we change the value of x to -x and we floor -x, we get a different value than the original.

Step-by-step explanation:
Divide both sides by -4−4.
m−26=3m
Subtract mm from both sides.
−26=3m−m
Simplify 3m - m to 2m.
−26=2m
Divide both sides by 2
− 26/2=m
Simplify 26/2 to 13
-13=m
Switch sides.
m=13
Answer:
-13
Step-by-step explanation:
1. First distribute
2. Then get m on one side by adding 4m to both sides
3. Combine the numbers with the variable m
4. You need to get m by itself so divide both sides of the equation by -16
5. You should get m=-13
1.-4(m-26)=-4m+104 4m+4m+104=-12m
2. 104=-12m-4m
3. 104=-16m
4. 104/-13=-16/-16m
5. -13=m
