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
12/6 x 12=
simplify the answer
Step-by-step explanation:
[tex] \frac{12}{6} \times \frac{12}{1} = 24[/tex]

Kenny is ordering uniforms for both the girls’ and boys’ tennis clubs. He is ordering shirts for 43 players and two coaches at a total cost of $658.35. Additionally, he is ordering visors for each player at a total cost of $368.51. How much will each player pay for the shirt and visor?

Simple answer
Need b4 10:00
Thanks!
Answer:
$22.82. Explanation: There are 45 total shirts and visors needed, for the 43 players and 2 coaches. So divide each of the total costs by 45 , to see how much each individual person pays:
SHIRT:
658.38/45 =$14.63 per person
VISTOR:
368.51/45 =$8.19per person
Each person is buying a shirt and a visor, so combine these two prices:
14.63+8.19=$22.82per person.
Find the sum of 1/3x and 2/5x
Answer:
The sum of 1/3x and 2/5x will be:
[tex]\frac{1}{3}x+\frac{2}{5}x=\frac{11}{15}x[/tex]
Step-by-step explanation:
Finding the sum of 1/3x and 2/5x.
i.e.
[tex]\frac{1}{3}x+\frac{2}{5}x[/tex]
Factor out common term x
[tex]\frac{1}{3}x+\frac{2}{5}x=x\left(\frac{1}{3}+\frac{2}{5}\right)[/tex]
as
[tex]\frac{1}{3}+\frac{2}{5}=\frac{5+6}{15}=\frac{11}{15}[/tex]
so the expression becomes
[tex]=\frac{11}{15}x[/tex]
Therefore, the sum of 1/3x and 2/5x will be:
[tex]\frac{1}{3}x+\frac{2}{5}x=\frac{11}{15}x[/tex]
Twice a number increased by seven is equal to five. Which of the following represents the equation and solution for this statement?
2 n + 7 = 5; n = -4.5
2 n = 7 + 5; n = 6
2 n + 7 = 5; n = -1
2( n + 7) = 5; n = -4.5
Hey there!
The answer to your question is the third option: 2n + 7 = 5; n = -1
"twice a number increased by 7" would represent 2n + 7, and if it's equal to 5, it would be 2n + 7 = 5. That rules out the last option, and the second option. Now, we have to solve for "n":
2n + 7 = 5 Step 1: Write the equation.
2n = -2 Step 2: Subtract 7 from both sides.
n = -1 Step 3: Divide both sides by 2.
Therefore, "n" is equal to -1, and the third option would be correct.
Hope it helps! Have a great day, and good luck on your assignment!

A bicycle wheel has outer diameter 32cm. How far will the cyclist travel if the wheel rotates 100π times? Give your answer in kilometres and correct to two decimal places.
Answer:
[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]
Step-by-step explanation:
Diameter [tex]d=32cm=0.32m[/tex]
Number of rotations [tex]N=100\pi[/tex]
Generally the circumference of the wheel is mathematically given as
[tex]C=2\pi r[/tex]
[tex]C=2\pi (0.32)^2/4[/tex]
[tex]C=1.005309649m[/tex]
[tex]C=1.0m[/tex]
Generally the total distance traveled T is mathematically given as
[tex]T=N*C[/tex]
[tex]T=100\pi *1m[/tex]
[tex]T=314.1592654m \approx 314.16m[/tex]
Total distance traveled T in Kilometres
[tex]T=314.1592654m[/tex]
[tex]T=\frac{314.1592654m}{1000}[/tex]
[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

if you are correct then ill give you brainliest answer!
Given :
A graph with a straight line on it.
To Find :
The equation of the line.
Solution :
From the given graph we can see that the line passes through point ( 0,6 ) and ( 4,10 ) .
Also, equation of line passes through two points [tex](x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex] is :
[tex]y - y_1 = (\dfrac{y_2-y_1}{x_2-x_1})( x - x_1)[/tex]
Putting all given values, we get :
[tex]y - 6 = (\dfrac{10-6}{4-0})( x -0)\\\\y - 6 = x\\\\y -x = 6[/tex]
Therefore, the equation of line is y - x = 6 .

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.

Dan rolls a fair dice 24 times.
How many times would Dan expect to roll an even number?
Answer:
It's going to be 4
Step-by-step explanation:
If (24 divided by 4) you get 6. So 4 basically is an even number :)
Answer:
Assuming a fair, six sided die, 4 would be expected to come up in one sixth of the trials, so 4 times in 24 rolls.
More formally:
Let X be the number of 4s rolled in 24 independent rolls of a fair six sided die. X is then distributed binomially with parameters n and p.
p = Probability of rolling a 4 = 1/6
n = Number of trials = 24
E [X] = np (by the properties of Binomial distribution)
E [X] = 4

Answer:
son = 18 years old.
Step-by-step explanation:
Father to son = f/s = 7./3 Cross Multiply
3f = 7s

f=60 - s
3(60-s)= 7s
180 - 3s = 7s
180 = 7s + 3s
180 = 10s
