Jordan has 300 pieces of candy. He gives Adrian ¼ pieces, 10% was given to Darien and he gave his little brother 25 pieces. Explain in writing (typing) how to find the number of pieces each person received then explain in writing (typing) how to find the number of pieces Jordan has left. (Remember to write 5 or more complete sentences)
Answer:
300-225=74 pieces
Step-by-step explanation:
1/4 of 300= 75
10% of 300 = 30
lil bro has 25

Answer:
son = 18 years old.
Step-by-step explanation:
Father to son = f/s = 7./3 Cross Multiply
3f = 7s
f + s = 60
f=60 - s
3(60-s)= 7s
180 - 3s = 7s
180 = 7s + 3s
180 = 10s
s = 180/10
s = 18
Based on the scatterplot and residual plot, is a linear
model appropriate for the growth of stock price?
A small technology company started offering shares of
stock to investors in 1987. At that time, the price of
one share of stock was $0.39. Since then, the
company has experienced rapid growth. Twenty-two
years later, the price of a single share of stock has
risen to over $110. The scatterplot shows the number
of years since the initial stock offering in 1987 and the
price of the stock.
O Alinear model is appropriate because the
regression line fits the scatterplot well.
O Alinear model is not appropriate because the
residual plot is centered about zero.
Alinear model is not appropriate because the
residual plot shows a clear pattern
Alinear model is not appropriate because the
scatterplot shows a clear pattern

Answer:
C
Step-by-step explanation:
These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.
What is the Scatter plot?The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.
A linear model is applicable if we can create a linear equation based on the connection between the independent and dependent variables (because there is no constant rate of change).
These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.
Thus, despite its being curved, a linear model is adequate for this time and price scatterplot.

Write an equation in paint-slope form of the line that passes through the point (3, 5) and has a slope of m = - 1
9514 1404 393
Answer:
y -5 = -(x -3)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
For m=-1 and (h, k) = (3, 5), the equation of the line is ...
y -5 = -(x -3)
Answer:
y-5=-1(x-3)
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)

Nicholas got a 2% raise. His previous salary was $12,000. What will be his next salary?
Answer: 240
Step-by-step explanation:
1. 12,000×.04=240
2. 12,000+240= 12,240
Answer:
$12,240
Step-by-step explanation:
$12,000 = 100%
$12,000 / 100 = $120
$120 = 1%
$120x 2 = %240.
$240 = 2%
$12,000+ 240 = $12,240

Answer:
2x+5y=13
y=x+7
Step-by-step explanation:
The linear functions are the ones Without exponents on the variables because the ones with exponents don't make a straight line. So:
2x+5y=13
y=x+7
f (x) = x2 + 4

Answer:
f(x)=X^2+4
f(x)=42
42=X^2+4
X^2+4=42
X^2=42-4

What is the value of x in the system of equations shown below?
5x + 4y = 1
y = 1 - x
Answer:
x=-3
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
Plug in
5x + 4(1 - x) = 1
(y gets replaced by 1 - x)
Multiply
5x + 4 - 4x = 1
(multiply 4 by whats in the parenthesis)
Combine Constants
5x - 4x = -3
(constant = numbers without a variable)
(separate constants from variables = numbers with letters)
Combine Variables
1x = -3
(then you got your answer and you can take the "1" off the x)
Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
1) A dilation factor of 2
2) A dilation factor of 4
3) A dilation factor of 1/2
4) A dilation factor of 1/4
Given:
A transformation was performed on PQRS to form P'QʻR'S'.
To find:
The transformation.
Solution:
The given graph shows two similar polygons. It means, dilation was performed.
From the given graph it is clear that,
[tex]PS=2[/tex] units
[tex]P'S'=1[/tex] units
Now,
[tex]\text{Scale factor}=\dfrac{P'S'}{PS}[/tex]
[tex]\text{Scale factor}=\dfrac{1}{2}[/tex]
A dilation factor of [tex]\dfrac{1}{2}[/tex] was performed on PQRS to form P'QʻR'S'.
Therefore, the correct option is (3).

Answer: A. A' (0, 6), B' (0, 4), C' (-3, 3)
Step-by-step explanation:
A (3, 0), B (3, -2), C (0, -3)
A translation by vector <-3, 6>
Add the x-coordinate of each points to -3 and add the y-coordinates to 6
A (3, 0) -> 3 + -3 = 0 0 + 6 = 6 A' (0, 6)
B (3, -2) -> 3 + -3 = 0 -2 + 6 = 4 B' (0, 4)
C (0, -3) -> 0 + -3 = -3 -3 + 6 = 3 C' (-3, 3)
A' (0, 6), B' (0, 4), C' (-3, 3)
Hope this helped!
