Answer:
This is the in and out box where you can plug in the numbers in the x box into the above equations.
y = 7(6) - 3
y = 39
y = 7(5) - 3
y = 32
y = 7(-9) - 3
y = -66
y = 7(1) - 3
y = 4
y = 7(2) - 3
y = 11
Matthew is given a $25 music gift card for his birthday. He downloads one song and the value of the card is $23.50. After two downloads, its value is $22. Write a formula to represent the remaining value on the card as an arithmetic sequence. What is the value of the card after 10 downloads? The value of the card after 10 downloads is
The formula to represent the remaining value of the card is aₙ = 26.5 - 1.5n
The value of the card after ten downloads is $10
Arithmetic formulaaₙ = a + (n - 1)d
where
a = first term
d = common difference
n = number of terms
Therefore,
a = 25
d = 23.5 - 25 = - 1.5
Therefore,
aₙ = 25 + (n - 1)(-1.5)
aₙ = 25 - 1.5n + 1.5
aₙ = 26.5 - 1.5n
After ten download the value of the card will be as follows,
26.5 - 1.5(11) = 26.5 - 16.5 = $10

solve the equation 3/x-4=1/5
Answer:
The very first thing we want to do in this equation is to isolate x on one side (preferably the left side).
3/x - 4 = 1/5
We get rid of any constants first, by performing the inverse property;
The inverse property of subtraction is addition, so we add 4 to both sides:
+4 +4
3/x = 4 1/5
3 is being divided by x, so the inverse operation of division is multiplication. So we multiply by 1/3 on both sides.
x1/3 x1/3
X = 1 4/10 which simplifies to 1 2/5.
In a National Achievement Test, Joshua obtained a score of 88. In the standardization of the test, μ = 78 and σ = 10. How would you communicate Joshua’s score to his parents? Explain your answer in writing
Using the normal distribution, Joshua's score is communicated as being in the 84th percentile.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 78, \sigma = 10[/tex].
He scored 88, hence X = 88 and his z-score is of:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{88 - 78}{10}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a p-value of 0.84.
Hence, Joshua's score is communicated as being in the 84th percentile.

nth term of 1,2,4,8,16,32,64,...
Answer:
2^(n-1)
Step-by-step explanation:
To find the nth term of the sequence 1, 2, 4, 8, 16, 32, 64,..., we can observe that each term is obtained by multiplying the previous term by 2. Therefore, the pattern can be described by the formula:
nth term = 2^(n-1)
In this formula, n represents the position of the term in the sequence.
For example: I
If we want to find the 5th term, we substitute n = 5 into the formula:
5th term = 2^(5-1) = 2^4 = 16
So, the 5th term of the sequence is 16.
Find the measurement of the missing angles.
Answer:
Answers to 1 and 5:
Q1 Angle 1: 129 degrees
Q1 Angle 2:116 degrees
Q5 Angle 1: 143 degrees
Q5 Angle 1: 78 degrees
Step-by-step explanation:
I cannot solve all of these, however I can still solve some of them. We know that one side of a straight line is 180 degrees.
Question 1:
If the angle that is next to angle 1 is 51 degrees, then we simply do: 180-51. The result will be 129 degrees.
The angle next to angle 2 is 64. 180-64= 116 degrees.
Question 5:
The angle next to angle 1 is 37. 180-37= 143 degrees.
The angle next to angle 2 is 102. 180-102=78 degrees.

Given that x = 7.3 m and θ = 40°, work out AB rounded to 3 SF.
Answer:
AB ≈ 4.69
Step-by-step explanation:
using the sine ratio in the right triangle
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{AB}{x}[/tex] , then
sin40° = [tex]\frac{AB}{7.3}[/tex] ( multiply both sides by 7.3 )
7.3 × sin40° = AB , then
AB ≈ 4.69 ( to 3 sf )
Does anyone know how to do this
Answer:
No
Step-by-step explanation:
These two triangles cannot be proven similar as there is only 1 angle which is shared between the two, that being: HMG=JMK since they are vertically opposite angles.
To prove 2 triangles are similar we need at least 2 equal angles.
+ Note that no equal sides are shared by the triangles.

At the beginning of the summer, the water level of a pond is 2 feet below its normal level. After an unusually dry summer, the water level of the pond dropped another 1 1/3 feet. Write an equation to show how far above or below the normal water level the pond is at the end of the summer.
Answer:
x - ( 2 + 1 1/3)
=x- 3 1/3
- 3 1/3 feet
The water level of a pond falls 3 1/3 feet below its normal level.
Step-by-step explanation:
The water level of a pond is 2 feet below its normal level.
The water level of the pond dropped another 1 1/3 feet.
So the total level dropped is 2 + 1 1/3
= 2 + 4/3
= 6+4/3= 10/3 = 3 1/3 feet below the normal.
Suppose the normal is at zero then the level of the pond is at the end of the summer is 0 - 3 1/3 = - 3 1/3 feet.
If we represent the normal by x then the equation becomes
x- 3 1/3 feet to show the water level at the end of summer.
Or it can also be written as
x - ( 2 + 1 1/3)

What polynomial has quotient

Answer:
[tex]x^3+9x^2+16x-6[/tex]
Step-by-step explanation:
When you learned to divide numbers, you said that 10 divided by 2 has quotient 5 since 5 times 2 was 10.
Same difference, let's multiply the two polynomials:
[tex](x^2+6x-2)(x+3) = x^3+9x^2+16x-6[/tex].
that assuming that you want no remainder. If you care about the remainder, just change the constant term with anything you want. the distance from [tex]-6[/tex] will be your remainder.
