Find the equation of the linear function represented by the table below in slope-intercept form.
x: 0,1,2,3,4
y: -6,4,14,24,34
Answer:
y = 10x - 6
Step-by-step explanation:
If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.
Note that the first pair is (0, -6) and the last pair is (4, 34). The 'run' is from x = 0 to x = 4, a 'run' of 4. The 'rise' is from -6 to34, a 'rise' of 40. Thus, the slope of this line is m = rise / run = 40/4 = 10.
Again using the coordinate pair (0, -6), along with the slope-intercept form of the equation of a straight line, we get:
-6 = 10(0) + b, so we know that b = - 6 and that the equation of this line must therefore be:
y = 10x - 6
The required slope-intercept form of the function is y = 10x - 6.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute 2 pairs from the table in the above equation,
m = (4 + 6)/(1-0)
m = 10
Now put the slope and one pair in the slope-intercept form of the equation
y - y₁ = m (x - x₁)
y + 6 = 10(x - 0)
y = 10x - 6
Thus, the required slope-intercept form of the function is y = 10x - 6

The school band is going to buy candy bars for $430 and sell them at school for $1.50 each. The band has to raise $1,350 to help pay for a trip. Write and inequality that represents how many candy bars x the band has to sell to make enough money for the trip.
Answer:
x = 900 or 1.50 * x = 1,350 (Though I advise you to use x = 900)
Step-by-step explanation:
Divide 1,350 by 1.50 to see that they need to sell exactly 900 bars. We can fact check by using a calculator to do the equation 1.50 * 900 = 1,350.

Jason had $6 in his lunch account at school on Monday. He spent $2 on lunch on Tuesday, deposited $7 on Wednesday and brought lunch from home. He bought lunch on Thursday for $5 and on Friday, he bought lunch again for $4. How much does Jason have on Friday AFTER he bought lunch?
Answer:
$2
Step-by-step explanation:
Credits:
Jason initial amount in his account = $6
Amount deposited for the week = $7
Total credit = $7+$6
Total credit = $13
Debit:
Cost of lunch bought on Tuesday = $2
Cost of lunch bought on Thursday = $5
Cost of lunch bought on Friday = $4
Total cost of lunch for the week = $2+$5+$4 = $11
Amount debited = $11
Balance left after he bought lunch on Friday = amount credited - amount debited
Balance = $13-$11
Balance = $2
Hence Jason had $2 balance left after buying his Friday lunch.
Among 320 randomly selected airline travelers, the mean number of hours spent travelling per year is 24 hours and the standard deviation is 2.9. what is the margin of error, assuming a 90% confidence level? round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
0.3
A. greater than 0.3
The Margin of error is 0.3 when assuming a 90% confidence level.
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
MOE = z score * s/√n
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
here, we have,
It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.
It is required to find the margin of error when the confidence level is 90%.
We have in the question:
at 90% confidence interval = 1.645 (From the Z score table)
s = 2.9
n = 320
Put the above values in the formula, we get:
MOE = 0.2666
Rounding the nearest tenth:
MOE = 0.3
Thus, The Margin of error is 0.3 when assuming a 90% confidence level.

Step-by-step explanation:
you have to set 6x-7 equal to 5x-1 which equals x=8 which now you replace x in 6x-7 with 8 which makes the equation 6(8)-7 which equals 41.
Answer:
Since M is the midpoint that means that LM is equal to MN so therefore
6x-7=5x+1
-5x from both sides
x-7=1
add 7 to both sides
x=8

Circle A has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. The diameter of circle B is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)
The value of pi is about 3.14, and it is the same when using both the area and circumference.
How to calculate circumference?The circumference is given by:
Circumference = π * diameter
For circle A:
25.12 = π * 8
π = 3.14
For circle B:
9.42 = π * 3
π = 3.14
The area is :
Area = π * diameter² / 4
For circle A:
50.24 = π * (8²)/4
π = 3.14
For circle B:
7.065 = π * (3²)/4
π = 3.14
The value of pi is about 3.14, and it is the same when using both the area and circumference.

solve the following equation for g: 2(g - h)=b + 4
Answer:
The steps to do this :
[tex]2(g - h) = b + 4[/tex]
[tex]g - h = \frac{b + 4}{2} [/tex]
[tex]g = \frac{b + 4}{2} + h[/tex]
[tex]g = \frac{b}{2} + \frac{4}{2} + h[/tex]
[tex]g = \frac{b}{2} + 2 + h[/tex]
2(g - h)=b + 4
Use the distributive property on the left side:
2g - 2h = b +4
Add 2h to both sides:
2g = 2h + b + 4
Divide both sides by 2:
g = (2h + b + 4)/2
Simplify:
g = b/2 + 2 + h ( note the order of h, 2 and b/2 can be different)

Total number of problems in a math test = 7
Total points given to each problem if it is correct = 10
Every text taker receives points for taking a test = 30
Let x represents number of correct answers given by the test taker and f(x) be the total score earned by the test taker.
Now, the function or linear equation in two variable which represent the given scenario is

There are about 1.61 kilometers in 1 mile. Let LaTeX: xx represent a distance measured in kilometers and LaTeX: yy represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distance measured in miles.
Answer:
1.61 x km= y miles
x km= y/ 1.61 miles
Step-by-step explanation:
Let x represent the distance in Kilometers and y represent the distance in miles then
1.61 x km= y miles
Now if we have 5 miles then
1.61(5) km = 5miles
8.05 km = 5 miles
Similarly if we want to express 1 km in miles the equation would be
x km= y/ 1.61 miles
So for 5 km the miles would be
5 km = 5/1.61 miles
5 km = 3.1055 miles
