graph the line that passes through the points (-4, -9) and (1,1) and determine the equation of the line
Answer:
The slope is (10,4)
Step-by-step explanation:
I have linked a picture to the graph I used as reference. The equation in y=mx+b form is y=10/4+0 or something like that I'm unsure about making the equation because there is no y-intercept
What is the equation of the line passing through the points (2/5, 19/20) and (1/3, 11/12) in slope-intercept form?
A. y = 1/2x -3/4
B. y = 1/2x + 3/4
C. y = 3/4x -1/2
D. y = 3/4x + 1/2

The stemplot below displays the times, in seconds, for 25 students to run 100 meters.
A stemplot titled 100 meter times (seconds) has values 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.
Which of the following is the correct five-number summary?
22, 24, 26, 28, 29
23, 24.5, 26, 28, 29
22, 24, 27, 28, 30
22, 24.5, 26, 28, 30
Given:
The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.
To find:
The five-number summary.
Solution:
We have,
22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30
Divide the data values on 2 equal parts.
(22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30)
Divide each parentheses in two equal parts.
(22, 23, 23, 24, 24, 24), (25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28), (28, 28, 28, 29, 29, 30)
Now,
Minimum value = 22
[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]
Median = 26
[tex]Q_2=\dfrac{28+28}{2}=28[/tex]
Maximum value = 30
So, the five number summary is 22, 24.5, 26, 28, 30.
Therefore, the correct option is D.
the train travels 16 miles in 20 minutes, at this rate how, many muients will it take to travel12 miles
Answer:
sorry if this is confusing
Step-by-step explanation:
16 miles = 12 miles
------------ ----------------
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240

Answer:
(D). (8, - 5)
Step-by-step explanation:
Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)
Coordinates of the midpoint are ( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )
(x² - 10x + 25) + (y² + 2y + 1) = 25
(x - 5)² + (y + 1)² = 5²
(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)
5 = (2 + x) / 2 ⇒ x = 8
- 1 = (3 + y) / 2 ⇒ y = - 5
(D). (8, - 5)
The ratio of the number of fiction books to the number of non-fiction books in a libary is 5:2 if there are 1421 fiction and non fiction books altoghter how many more fiction than non fiction books
Given:
The ratio of the number of fiction books to the number of non-fiction books in a library is 5:2.
Total number of books = 1421
To find:
The number of books of each type.
Solution:
Let the number of fiction books be 5x and number of non-fiction books be 2x.
Total number of books = 1421
[tex]5x+2x=1421[/tex]
[tex]7x=1421[/tex]
[tex]x=\dfrac{1421}{7}[/tex]
[tex]x=203[/tex]
Now,
Number of fiction books : [tex]5(203)=1015[/tex]
Number of non-fiction books : [tex]2(203)=406[/tex]
Therefore, the number of fiction and non-fiction books are 1015 and 406 respectively.

step 1: multiply the 5 to the bracket =5p+10-p
step 2 : subtract the p from the 5 p =5p-p+10 = 4p+10
2.
step 1 : multiply the 3 to the bracket = 8h + 12h-18
step 2: add the 8h to the 12h = 20h - 18
3.
multiply the 4 to the bracket = 4x+32 +9x
add 4 x to 9 x = 13x +32
4.
multiply the 2 to the bracket = 6y +8 +9
add the 8 to the 9 = 6y + 17
5.
multiply to six to the bracket =9x + 12x +18
add the 9 and 12 x = 21x+18
6 .
multiply the 3 to the bracket = 9m + 3 +2m
add the 9m to 2m = 11m+ 3
7.
multiply the 2 to the bracket = 2r + 18 -6
subtract the 18 from the six = 2r +12
8 .
multiply the five to the bracket = 15 d + 40
9.
multiply the 4 to the bracket = 8m+8+3m
add the 8 m to the 3 m = 11m + 8
10 .
multiply the 10 to the bracket= 5y +20 +10 y
add the 5y and the 10 y = 15y + 20

A student charges $31.50 for 3 hours of babysitting. If the amount the student earns babysitting is proportional to the hours spent babysitting, which equation models the amount of dollars, y, the student earns for x hours of babysitting?
A. y is equal to 0.1 x
B. y is equal to 3.0 x
C. y is equal to 10.5 x
D. y is equal to 31.5 x
Answer:
C) y is equal to 10.5x
Step-by-step explanation:
$31.50 is charged for 3 hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50
this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x
and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.
Solve the system by substitution. Check your answer.
a+b-4c =4
- 2b + c = -11
C= - 1
Answer: c=-1,b=5,a=-5
Step-by-step explanation: If c=-1, substitute it into the second equation first. The second equation becomes -2b-1=-11, simplify it becomes -2b=-10, divide by 2 it becomes -b=-5, so b=5. Then you substitute b and c into the first equation. The first equation becomes a+5+-(-4)=4, simplify it becomes a+5+4=4, Simplify again it becomes a=-5.
