what is the initial value of the linear function that represents this situation
Answer:
As per the statement: Hannah already had 44 photos on her camera when she arrived in Rome.Then she took 24 photos each day for 6 days.
Let x represented day and y represents the number of photo
Total number of 24 photo in x days is, 24x
then; as per the given statement our equation becomes;
y = 24x+44 .....[1]
now, to find the total number of photos took by Hannah for 6 days in Rome;
put x = 6 in [1] we get;
y = 24(6) + 44 = 188
Therefore, the total number of photos on Hannah's Camera is, 188 photos.
To, find the initial value for the linear function y =24x +44.
Initial value or y-intercept, is the output value when the input of a linear function is zero i.e, x = 0.
Substitute x =0 in y =24x +44
y= 24(0) + 44
y = 0 + 44
y = 44
Therefore, the initial value for the equation y =24x+44 is 44 photos.
Answer:its 44 photos!

find the equation of the line passes through the pints (-2,3) and (1,-4).
Answer:
[tex]3y+7x=-5[/tex] is the required equation.
Step-by-step explanation:
We have been given two points: (-2,3) and (1,-4)
We have a formula to find the equation with two points:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}\cdot (x-x_1)[/tex]
Here, we have:
[tex]x_1=-2,x_2=1,y_1=3,y_2=-4[/tex]
On substituting the values in the formula we get:
[tex]y-3=\frac{-4-3}{1-(-2)}\cdot (x-(-2))[/tex]
[tex]\Rightarrow y-3=\frac{-7}{3}\cdot (x+2)[/tex]
On further simplification:
[tex]3y-9=-7(x+2)[/tex]
[tex]\Rightarrow 3y-9=-7x-14[/tex]
After rearranging the terms
[tex]3y+7x=-14+9[/tex]
After final simplification we get:
[tex]3y+7x=-5[/tex]

Kali runs 10 laps around a track each day each lap around the track is 400 meters how may days will it take Kali to run a total of 12 kilometers
Answer:
30
Step-by-step explanation:
Convert 12 km to metres
1000 m = 1 km
12 km = 12 × 1000/1
Distance = 12 000 m
Kali takes 1 day for 400 m, so
Time = 12 000 × 1/400
Time = 30 da
It will take Kali 30 da to run 12 km.

uppose that y varies inversely with x. Write an equation for the inverse variation. y = 2 when x = 5
Answer:
An equation for the inverse variation y = 2 when x = 5 is:
y=10/x
Step-by-step explanation:
Suppose that y varies inversely with x:
y=k/x
Write an equation for the inverse variation y = 2 when x = 5
Substituting y by 2 and x by 5 in the formula above:
2=k/5
Solving for k: Multiplying both sides of the equation by 5:
5(2)=5(k/5)
10=k
k=10
Then the equation is:
y=k/x
y=10/x

(RIGHT ANSWERS ONLY PLEASE!!!)
Answer:
Problem 1. Answer: D
Problem 2. Answer: A
Problem 3. Answer: C
Problem 4. Answer: D
Step-by-step explanation:
Problem 1:
A pack is targeted to weigh 9.25 oz.
A pack can be up to 0.23 oz off, either over or under weight.
The pack cannot weigh less than 9.25 oz - 0.23 oz or more than 9.25 oz + 0.23 oz.
The following compound inequality represents the rejected weights.
x < 9.25 - 0.23 or x > 9.25 + 0.23
Subtract 9.25 from both sides of both inequalities.
x - 9.25 < -0.23 or x - 9.25 > 0.23
Change to an absolute value inequality.
|x - 9.25| > 0.23
x - 9.25 < -0.23 or x - 9.25 > 0.23
x < 9.02 or x > 9.48
Problem 2:
Almond trees produce 12a
Macadamia nut trees produce 8m
Yield is 250
12a + 8m = 250
Problem 3:
8.8 m/s converted into km/h
1000 m = 1 km
60 sec = 1 min
60 min = 1 hr
8.8 m/s * (1 km)/(1000 m) * (60 s)/(1 min) * (60 min)/(1 hr) =
= 31.68 km/h
Problem 4.
Let number of alternative schools be a.
Let number of charter schools be c.
"the number of charter schools is 4 less than twice the number of alternative schools"
c = 2a - 4
There are 48 charter schools, so c = 48. Now we solve for a.
48 = 2a - 4
52 = 2a
a = 26

You are on a cycling trip around Europe with friends. You are coming towards the end of your trip and have been asked by an online cycling blog to give some details about the cost of your trip, the places you visited and how many kilometres you have cycled. Look at your kilometres cycled record for each week:
Answer:
Based on the questions asked on the screen shot of the problem, the range of time spend cycling each week is 16 hours and the average number of calories burned per day in week 5 was 1200.
Step-by-step explanation:
Given the data in the problem for the number of weeks versus the amount of hours spent cycling, in order to find the range you would subtract the highest number of hours in a given day (22 - week 4) by the lowest number of hours in a given day (6 - week 1), or 16. For week 5, if you were to burn 8400 calories for the week, assuming that you cycled for all seven days, you would take your total calories burned and divide by the number of days to get approximately 1200 calories per day.

In March Delphine’s house had 40% more snowfall than in February. Delphine’s house has F centimeters of snowfall in February
Answer: In March Delphine's house has 1.4*F centimeters of snow.
Step-by-step explanation:
We know that in March, the snow was 40% more than in Februray.
First we need to write 40% in decimal form, for this we divide it by 100%
40%/100% = 0.4
Now, in Februray Delphine's house has F centimeters of snow.
If F corresponds to the 100%, 0.4*F corresponds to the 40%
Now, in march we have a 140% of snow, this is:
Snow = F + 0.4*F = 1.4*F
In March Delphine's house has 1.4*F centimeters of snow.

Step-by-step explanation:
First blank:
The equation is x + 6.5 = 13.
To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the
D. Subtraction property of equality
Second blank:
Subtract 6.5 from both sides.
x + 6.5 = 13

Erica babysits for 4.5 hours and is paid $27. If the people she babysits for have $34 to pay her, how long can they stay out?
Find the algebraic equation
Answer:
5 hours 40 minutes can they stay out.
An algebraic equation, y =6x
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.
Let x represents the hours and y represents the cost.
As per the statement: Erica babysits for 4.5 hours and is paid $27.
Unit rate per hour(m) = [tex]\frac{27}{4.5}= $6[/tex]
Line of equation with no intercept is given by:
y = mx .....[1]; where m represents the slope or unit rate.
Also, it is given if the people she babysits for have $34 to pay her.
⇒ y = $34
substitute the given values in [1] to solve for x;
[tex]34 = 6 \times x[/tex]
Divide both sides by 6 we get;
[tex]x = \frac{34}{6} = 5\frac{4}{6}[/tex] hours
or
x = 5 hours 40 minutes
Therefore, 5 hours 40 minutes can they stay out.
Also, algebraic equation: y =6x

(72x.05)=36x2+(.80x36)=288
288+72=360
The Number of people who became members in month, x = 5 are 76
The equation given represents a linear expression representing :
x = total number of people who became members that monthTo obtain the number of people who became members in a particular month, we input the value of x into the equation and calculate the output :
For instance, if Number of month, x = 5
The Number of people who became members is :
y = 0.8(5) + 72
y = 4 + 72
y = 76
Hence, the Number of people who became members in month, x = 4 are 76

Write the equation of the line that passes through point (-10, -5) and is parallel to the line represented by the equation y = -2x + 7.
Answer:
y + 5 = -2(x + 10)
Step-by-step explanation:
To make the line parallel, we need the same slope as the line. Because it is in slope-intercept form, we know that the slope, or [tex]m[/tex], equals -2.
Also, because we have the point that it passes through, we have enough information to put the values into point-slope form, which is:
[tex]y-y_{1}=m(x-x_{1})[/tex]
y + 5 = -2(x + 10)

A business owner spent $4000 for a computer and software. For bookkeeping purposes, he needs to post the price of the computer and software separately. The computer costs 4 times as much as the software. What is the cost of the computer?
Answer:
$3200
Step-by-step explanation:
Let price of computer be [tex]c[/tex] and price of software be [tex]s[/tex]
From this statement, we can write: [tex]c+s=4000[/tex]
"The computer costs 4 times as much as the software"From this statement, we can write: [tex]c=4s[/tex]
Substituting 2nd equation into the first and solving for [tex]s[/tex]:
[tex]c+s=4000\\(4s)+s=4000\\5s=4000\\s=\frac{4000}{5}=800[/tex]
We want to know price of computer, which is 4 times this, so we have:
[tex]c=4(800)=3200[/tex]
Thus, the computer costed $3200
