Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (13, 1) into the partial equation
1 = 13 + c ⇒ c = 1 - 13 = - 12
y = x - 12 ← equation of line
David purchased these school supplies: 5 notebooks for $1.29 each 2 pens for $1.19 each 12 pencils for $0.05 each 6 erasers for $0.15 each How much change should David receive from $20?
Answer:
The answer is $9.67.
Step-by-step explanation:
Notebooks: 5 * 1.29 = 6.45
Pens: 2 * 1.19 = 2.38
Pencils: 12 * 0.05 = 0.60
Erasers: 6 * 0.15 = 0.90
Total: 6.45 + 2.38 + 0.60 + 0.90 = 10.33
Change: 20 - 10.33 = 9.67
Find the slope plssss
Answer:
5/2
Step-by-step explanation:
Answer:
The slope of this line is - 5/2.
Step-by-step explanation:
In order to get from one red dot to another, you must go up 5 and to the left 2, because we are going left instead of right, the slope is negative. It doesn't matter which number you assign the negative sign. The entire formula for the line is y=- 5/2x - 3

Answer:
6000 grams / sec
Step-by-step explanation:
1 kg = 1000 grams
1 min = 60 sec
360 kg (1000grams/1 kg) = 360000grams
360000 grams/min (1 min/ 60sec) = 6000 grams / sec

Step-by-step explanation:
Arrange the items in ascending order
2 , 3 , 5 , 5 , 6 , 7 , 9 , 14 , 19
Median = middle term = (n+1)/2 = (9 + 1)/2 = 10/2 = 5th term

Write the slope-intercept form of the equation of the line through the given points: (-2,13) and (4,1)
Answer: y = -2x + 9
Step-by-step explanation:
Points through which the line passes through are: (-2,13) and (4,1)
The slop intercept form will be in terms of:
y = mx + c
Find m first which is the slope:
= (Y₂ - Y₁) / (X₂ - X₁)
= (1 - 13) / (4 - (-2))
= -12 / 6
= -2
Using a point on the line and the slope, calculate c which is the y intercept:
Using point (-2,13) :
y = mx + c
13 = -2 * -2 + c
13 = 4 + c
c = 13 - 4
c = 9
Slope intercept form of line is therefore:
y = -2x + 9

Mother is 36
and she is 6 year older than raju 3 times
N is rajiu age
N = 36÷ ( 6 x 3)
= 36 ÷ (18)
N = 2
Raju is 2 years old

If she paid the store $67.50 (USD) and the membership is 20$ take that 20 and add 2.50 onto it till you get the answer BUT if you want to explain it all the way each month has about 30 days in it so 30x3=90 so she was there for 90 days. 90x$2.50=225 but we all know, she couldn't have rented that many... right? but the final answer is 19, you take 20 from 67.50 which was the membership and all you have to do is fill in that missing amount so take 2.50 and multiply till you get the answer.

Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject’s standardized test is given in the table.
A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
What is the mean of the distribution?
2.5
2.95
3
3.5
Answer:
The center for the distribution of scores appears to be higher for subject B than for subject A.
The mean of the distribution when X represent the score on a randomly selected exam so here the mean be like 2.95.
Calculation of the mean:Since
Column 1 is labeled score with entries 1, 2, 3, 4, 5.
Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
So it be like
= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)
= 0.18 + 0.40 + 0.78 + 0.84 + 0.75
= 2.95
Hence, the third option is correct.

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent the relationship between her labeling speed and the number of minutes it would take her to finish labeling. Complete the equation below: m = _________ where m is the number of minutes and s is the speed in books per minute.
Answer:
[tex]S = \frac{b}{m}[/tex]
Step-by-step explanation:
Given
[tex]Speed = s[/tex]
Required
Determine the expression for s
The speed is calculated as:
[tex]Speed = \frac{Number\ of\ books}{Time}[/tex]
Substitute S for speed
[tex]S= \frac{Number\ of\ books}{Time}[/tex]
Let the number of books be b and the time be m.
The expression becomes
[tex]S = \frac{b}{m}[/tex]
Hence, the expression for the scenario is:
[tex]S = \frac{b}{m}[/tex]
