Jerry had k pencils. darcy and leonard then gave jerry an additional x pencils each. which expression could represent the number of pencils jerry has now?
Answer:
[tex]k[/tex]+([tex]x[/tex]×[tex]x[/tex])
Step-by-step explanation:
k is the number of pencils jerry has, and x is the number of pencils darcy and leonard gave him EACH. So you need to multiply 'x' x2 to get the total ammount of pencils they gave him, then add 'k' to know how much in total he has now.

What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
The graph shows the value in the account after 2005.
0 indicates the year 2005.
1, 2, ...... indicates 2006, 2007, etc.
A) The value in 2007 corresponds to value of 2, which is 124.44.
True statement.
B) From 2013-2015 means that x values from 8 to 10.
Value of money during 2013-2015 = 180 - 166.19 = 13.81
From 2005-2007 means that x values from 0 to 2.
Value of money during 2005-2007 = 124.44 - 113 = 11.44
So Value of money during 2013-2015 is greater than that of 2005-2007.
True statement.
C) To find the amount account gained per year, find slope.
Slope = Change in y coordinates / Change in x coordinates
Take two points on the line (0, 113) and (2, 124.44)
Slope = (124.44 - 113) / (2 - 0) = 5.72
Hence the account gains $5.72 every year.
True statement.
D) Clearly the function is linear since the graph is a straight line.
Hence this is not a exponential growth.
Hence D is the false statement.

Step-by-step explanation:
y = 2(x – 3)2 - 4
Convert to standard form
Answer:
4x - y = 16
Step-by-step explanation:
y = 2(x – 3)2 - 4
When written in standard form, this will be the answer --->
4x - y = 16
Answer:
y = 2x² - 12x + 14
Step-by-step explanation:
The equation of a parabola in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = 2(x - 3)² - 4 ← expand (x - 3)² using FOIL
= 2(x² - 6x + 9) - 4 ← distribute parenthesis
= 2x² - 12x + 18 - 4
y = 2x² - 12x + 14 ← in standard form
A bag contains 2 red,5 blue,6 yellow, and 3 green crayons. What is the probability of selecting a red crayon, then without replacing it selecting an odd number that is (red, then green)
A.0
B.0.25
C.01
D.0.025
Answer: D.0.025
Step-by-step explanation:
Given: A bag contains 2 red,5 blue,6 yellow, and 3 green crayons.
Total crayons: 2+5+6+3=16
Probability of getting red crayon= [tex]\dfrac{\text{Number of red crayons}}{\text{Total}}[/tex]
[tex]=\dfrac{2}{16}=\dfrac18[/tex]
Without replacement, the probability of getting green crayon = [tex]\dfrac{\text{Number of green crayons}}{\text{Total}-1}[/tex]
[tex]=\dfrac{3}{15}=\dfrac15[/tex]
Required probability P(red then green)= [tex]\dfrac18\times\dfrac15=\dfrac1{40}=0.025[/tex]
Hence, correct option is D.0.025

Find the coordinates of the point 7/10
of the way from A to B.
A (-3,-6)
B(12,5)
9514 1404 393
Answer:
(7.5, 1.7)
Step-by-step explanation:
The point of interest (P) is the weighted average of the end points. The weights are the reverse of the lengths of the associated segments.
P = (3A +7B)/10
P = (3(-3, -6) +7(12, 5))/10 = (-9+84, -18 +35)/10 = (75, 17)/10
P = (7.5, 1.7)
Salim bought a fruitcake, cut off a piece from it, and ate the piece. The dimensions of the cake before and after he cut it, are shown below. What was the volume of the piece that Salim ate?
Answer:
C. 75 cu cm
75 cm³
Step-by-step explanation:
Volume of the cake when Salim bought it = length × width × height
= 15 cm × 6 cm × 5 cm
= 450 cm³
Volume of the cake after Salim cut a piece = length × width × height
= 12.5 cm × 6 cm × 5 cm
= 375 cm³
volume of the piece that Salim ate = Volume of the cake when Salim bought it - Volume of the cake after Salim cut a piece
= 450 cm³ - 375 cm³
= 75 cm³
volume of the piece that Salim ate = 75 cm³
The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1
Answer:
A
Step-by-step explanation:
Since the prisms are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )
4x = 16 ( divide both sides by 4 )
x = 4 → A
The value of x on the prism is 4.
What are Similar Figures?Similar figures are those figures which are having the same shape, but the sizes are different.
Given are two prisms.
We have to find the length of x.
Given that they are similar.
So the ratio between their dimensions is equal.
So,
x / 1 = 16 / 4
x = 4
Hence the value of x is 4.

Jayla has 500 stickers in a collection. She wants at least y stickers in her collection at the end of the month. She buys 25 stickers each day. Write an inequality tha
number of days. Enter your answer in the box provided.
Answer:
20
Step-by-step explanation:
500 divided by 25=20
The required inequality is 500 + 25x ≥ y which represents the given situation.
What is inequality?
Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let x be the number of days Jayla buys stickers.
The total number of stickers Jayla has at the end of the month is 500 + 25x.
To represent the inequality that Jayla wants at least y stickers in her collection at the end of the month, we can write:
500 + 25x ≥ y
This inequality states that the total number of stickers Jayla has (500 + 25d) is greater than or equal to the number of stickers she wants (y) at the end of the month.
It gives the minimum number of days Jayla should buy stickers to achieve her goal.

A loan used for buying a home is called a mortgage. The
Fernandez family is buying a
$375,000 home. They are taking
out a 30-year mortgage at a rate of 8%.
a. Compute the monthly payment.
b. Find the total of all of the monthly payments for the 30
years.
c. What is the finance charge?
d. Which is greater, the interest or the original cost of the
home.
Answer:
a. The monthly payment is approximately $2,751.62
b. The total of all monthly payment for the 30 years is approximately $990,582.175
c. The finance charge is approximately $615,582.175
d. The interest is greater than the original cost of the home
Step-by-step explanation:
a. The given parameters for the mortgage are;
The principal amount of the home Fernandez family is buying, P = $375,000
The number of years mortgage they take buy the home = 30 years
The percentage rate of the mortgage, r = 8%
The monthly payment, 'A', for the mortgage is given as follows;
[tex]A = \dfrac{ P \times \left (\dfrac{r}{12} \right ) \times\left (1 + \dfrac{r}{12} \right )^n}{\left (1 + \dfrac{r}{12} \right )^n - 1 }[/tex]
Where;
n = The number of monthly payments = 30 years × 12 months/year = 360 months
Therefore, by substituting the known values, we have;
[tex]A = \dfrac{ 375,000 \times \left (\dfrac{0.08}{12} \right ) \times\left (1 + \dfrac{0.08}{12} \right )^{360}}{\left (1 + \dfrac{0.08}{12} \right )^{360} - 1 } = 2,751.61715172[/tex]
The monthly payment, A = $2,751.61715172 ≈ $2,751.62
b. The total of all monthly payment for the 30 years = 360 × $2,751.61715172 ≈ $990,582.175
c. The finance charge = The total amount repaid - The amount that was financed = The interest payed on the amount financed
∴ The finance charge = $990,582.175 - $375,000 ≈ $615,582.175
d. The interest (approximately $615,582.175) is greater than the original cost of the home ($375,000)

What is a relative frequency?Relative frequency is a statistical term that describes the proportion or percentage of times that an event or value occurs within a dataset or sample.
It is calculated by dividing the number of times the event occurs by the total number of observations in the dataset or sample.
We have,
To find the relative frequencies of this data by rows or by columns, we need to divide each count by the total number of rooms occupied. The total number of rooms occupied is:
25 + 18 + 12 + 20 = 75
To find the relative frequencies by rows, we divide each count by the total for that row:
For Mountain View rooms:
King Bed: 25/(25+18) ≈ 0.58
Queen Bed: 18/(25+18) ≈ 0.42
For Ocean View rooms:
King Bed: 12/(12+20) ≈ 0.38
Queen Bed: 20/(12+20) ≈ 0.62
The table representing the relative frequencies by rows would be:
King Bed Queen Bed
Mountain 0.58 0.42
Ocean 0.38 0.62
To find the relative frequencies by columns, we divide each count by the total for that column:
For King Bedrooms:
Mountain View: 25/(25+12) ≈ 0.68
Ocean View: 12/(12+20) ≈ 0.38
For Queen Bedrooms:
Mountain View: 18/(18+20) ≈ 0.47
Ocean View: 20/(18+20) ≈ 0.53
The table representing the relative frequencies by columns would be:
King Bed Queen Bed
Mountain 0.68 0.47
Ocean 0.32 0.53
Note that we round the relative frequencies to the nearest hundredth.
Thus,
The table representing the relative frequencies by rows and columns is given above.
