The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is 4
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, = [tex]\dfrac{1}{3}[/tex]
Required:
To find the value of y
Solution:
The formula for the slope is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;
[tex]Slope, \, m =\dfrac{7-y}{5-(-4)} = \dfrac{7-y}{5+4} =\dfrac{1}{3}[/tex]
3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12
[tex]y = \dfrac{12}{3} = 4[/tex]
The value of, y = 4

How many ways can 7 students be selected from an organization of 30 to attend a national conference?
Determine the number of possibilities for selection. Express your solution in a complete sentence reflective of the scenario.
The number of possibilities for selection is 2,035,000 ways
This question has to do with the combination
Given the following parameters
Total number of students = 30 students
If 7 students are to be selected from a pool of 30 students, the number of ways this can be done is expressed as:
30C7 = 30!/(30-7)!7!
30C7 = 30*29*28*27*26*25*24*23!/23!*7!
30C7 = 30*29*28*27*26*25*24/7!
30C7 = 10,260,432,000/5040
30C7 = 2,035,800
This shows that the number of possibilities for selection is 2,035,000 ways

Find an equation for the horizontal line through the point (2,−8).
Answer:
X=2
Step-by-step explanation:
X is the horizontal line and in this coordinate pair, 2 is our X. Therefore X=2
Answer:
y = -8
Step-by-step explanation:
You can have a horizontal line parallel to the x-axis which is also known as y=c. Since you had the point (2,-8) you can simply write y = -8 as an equation.

WILL MARK BRAINLIEST <3 Each of the letters in the word "HANDIWORK" are on separate cards face down on the table. If you pick a card at random, what is the probability that the letter on it will fall between "F" and "Q" in the alphabet?
5/9
3/9
1/2
7/9
The probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9. Option A is correct.
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given the word "HANDIWORK", the total letters in the word are 9 letters.Total outcome = 9 lettersFor the number of events, we will have to find the letters between F and Q in the "HANDIWORK". The letters are n(E) = {H, N, I, O, K}Hence n(E) = 5Pr(the letter on it will fall between "F" and "Q" in the alphabet) = 5/9
Hence the probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9

Three integers sum to 57. The second integer is twice the first integer. The third integer is seven less than five times the first integer. What are the three integers?
Answer:
a=8
b=16
c=33
Step-by-step explanation:
Let's call the integers a, b, and c. (a is the first, b is the second, and c is the third.)
a+b+c=57
Write the second two sentences as equations.
b=2a
c=5a-7
Plug in these values of b and c to the original equation.
a+(2a)+(5a-7)=57
Solve for a:
a+2a+5a-7=57
8a-7=57
8a=64
a=8
Now, plug in your solution for a into the equations for b and c to solve for them.
b=2a=2(8)=16
c=5a-7=5(8)-7=40-7=33
You can add up your answers for a, b, and c to make sure you're correct.
a+b+c=8+16+33=57

Answer:
4th graph
6th graph
3rd graph
Step-by-step explanation:
Linear = y = x + 3
it is 4th graph
when you substitute x = 0 y is 3
and when y = 0 x is -3
Quadratic = y = 3x^2
It is 6th graph
for both positive and negative values of x, y is rapidly increasing
Exponential = y = 3^x
it is 3rd graph
for x = 0 y value is 1 because 3^0 = 1
for positive values of x, y is exponentially rising
for negative values of x it is nearly almost touches zero
Margie volunteered to supply heart-shaped sugar cookies for her third-grade class' Valentine's Day party. Her mom will use premade cookie dough in a tub and buy pink frosting and sprinkles, too. Margie would like to give one cookie to each of her 26 classmates. One tub of cookie dough makes 20 cookies and costs $9.95. The frosting will cover 30 cookies and costs $4.59. The package of sprinkles covers up to cookies 60 and costs $2.29. When Margie's sister, Nicole, hears about the cookies, she asks her mom if they can bake one cookie for each of the students in her class, too. Nicole is in fifth grade and she has 31 students in her class. How much will the ingredients cost for both of the classes?
Answer: $41.32
Step-by-step explanation:
1. Figure out how many students need cookies.
26 + 31 = 57, 57 students need cookies, thus they need to make at least 57 cookies.
2. Figure out which ingredients are still needed.
One tub of cookie dough makes 20 cookies, so to make 57 cookies, they will need at least three tubs. One frosting tin covers 30 cookies, so to cover 57 cookies, they will need at least two tins. One bag of sprinkles covers 60 cookies, so they will only need one bag, as 60 > 57.
3. Tally up the prices of each ingredient
Price of cookie dough = 9.95, amount of cookie dough needed = 3
9.95 * 3 = 29.85
Price of frosting = $4.59, amount of frosting needed = 2
4.59 * 2 = 9.18
Price of sprinkles = 2.29, amount of sprinkles needed = 1
2.29 * 1 = 2.29
4. Find the sum.
29.85 + 9.18 + 2.29 = 41.32
