A tie-dye kit with one T-shirt costs $15. Each additional T-shirt costs $4 more. Choose the explicit formula to represent the situation.
A. an = 11 + 4n
B. an = 4 + 15n
C. an = 19 + 4n
D. an = 15 + 4(n + 1)
Answer:
a
Step-by-step explanation:
i just took the test
The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n thus option (A) is correct.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.
As per the given,
Cost of a tie-dye kit + 1 T-shirt = $15
Additional T-shirt = $4
This, means,
Cost of a tie-dye kit + $4 = $15
Cost of a tie-dye kit = $11
The total cost with n number of T-shirts will be as,
[tex]a_{n}[/tex] = 11 + 4n
Hence "The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n".

-1, 11/3
1, 7/3
3, 1
6, -1
Please help if you know
Answer:
y=-.386x + 2.879
Explanation:
For these type of calculations, you would have to use a graphing calculator to use the linear regression function. What this does is, it takes the x & y values given on the chart and it gives you the best possible linear equation for the given data set.
The exact results were:
y = -0.3862928349 + 2.869158879

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound
To determine the number of pounds of tomatoes that she bought, x, Carina wrote and solved the equation as shown
below.
3.40+0.85x=5.27
0.85X= 8.67
X= 10.2 pounds
Where, if anywhere, did Carina make an error?
Answer:
Carina made an error in the beginning.
Step-by-step explanation:
Carina didn't do the inverse operation of adding 3.40. She added it to the 5.27 when she shouldve subtracted it. x=2.2 lbs. Hope this helps!

John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
Answer:
Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.
Step-by-step explanation:
(x + 4, y + 7) = Right 4, Up 7
NOT
(x - 4, y - 7) = Left 4, Down 7
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.
Step-by-step explanation:
Sample Response:The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

10. What is the value of x in the solution to the system of equations?
x – 2y = 7
3x + 2y = 21
+/-
Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.

Please solve the equation x+16=9x and show work please
Answer:
2
Step-by-step explanation:
x+16=9x
x-9x=-16
-8x=-16
x=2
+16=9
x+16=9xx+16=9x
Solve
Subtract
16
1616
from both sides of the equation
+16=9
x+16=9xx+16=9x
+16−16=9−16
Simplify
Subtract the numbers
=9−16
x=9x-16x=9x−16
Subtract
9
9x9x
from both sides of the equation
=9−16
x=9x-16x=9x−16
−9=9−16−9
Simplify
Combine like terms
Combine like terms
−8=−16
Divide both sides of the equation by the same term
−8=−16
-8x=-16−8x=−16
−8−8=−16−8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers

Megan cut a string into 4 equal pieces. Each piece is 4 fifths of a foot long. How many feet long was the string before Megan cut it? Enter your answer as a mixed number in the solution box. The string was feet long before Megan cut it.
Answer:
[tex]Total = 3\frac{1}{5}ft[/tex]
Step-by-step explanation:
Given
[tex]Pieces = 4[/tex]
[tex]Size = \frac{4}{5}ft[/tex]
Required
Determine the total size of the string
To do this, we multiply the number of pieces by the length of each piece.
[tex]Total = Pieces * Size[/tex]
[tex]Total = 4 * \frac{4}{5}ft[/tex]
[tex]Total = \frac{4 * 4}{5}ft[/tex]
[tex]Total = \frac{16}{5}ft[/tex]
Convert to mixed number
[tex]Total = 3\frac{1}{5}ft[/tex]

Step-by-step explanation:
To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6 , the six is in the tenths place , so we place 6 over 10 to create the equivalent fraction , 6 / 10
Need help with finding my solution and graphing !
Answer:
Step-by-step explanation:
Both the equations that you modelled are correct.
Use the substitution method to solve the system of equations
[tex]R+C = 526\\5R+4C=2327\\[/tex]
Take the first equation
[tex]R+C=526\\C=526-R[/tex]
Now this becomes our third equation and now insert it into our second equation
[tex]5R+4C=2327\\5R+4(526-R)=2327\\5R+2104-4R=2327\\R=2327-2104\\R=223[/tex]
Now insert R = 223 in any equation. Lets insert it into equation number three
[tex]C=526-R\\C=526-223\\C=303[/tex]
So 223 number of roll papers were sold and 303 number of candles were sold.
I have attached the graph below check it out.
Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.

Given vectors u = (2, -3) and v= (1, -1), what is the measure of the angle between the vectors?
O 11.3°
O 78.9°
O 92.2°
O 101.3°
Answer:
A) 11.3°
Step-by-step explanation:
got it right on edge :)
The measure of the angle between the vectors will be 11.3°. Then the correct option is A.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
The angle between the vector is given as,
[tex]\theta = \cos^{-1} \dfrac{u \cdot v}{\left|a \right|\left|b \right|}[/tex]
Given vectors u = (2, -3) and v= (1, -1).
Then the measure of the angle between the vectors will be
[tex]\theta = \cos^{-1} \dfrac{(2, -3)\cdot (1, -1)}{\sqrt{2^2+(-3)^2} \ \sqrt{1^2 + (-1)^2}}\\\theta = \cos^{-1} \dfrac{2 + 3}{\sqrt{13} \sqrt{2}}\\\theta = \cos^{-1} \dfrac{5}{\sqrt{26}}\\[/tex]
θ = 11.3°
Then the correct option is A.
