Answer:
if a line is like so it has a positive slope: / . IF a line is like this it has a negative: \
Therefore that leaves out -1/3 and -3
Either A or C is correct
From the y intercept (where the line intercepts the y axis), in this case 2, to the next point on the line (3, 3) it goes up 1 and over 3 to get to that point from the intercept. Therefore the slope is 1/3. (Rise/run)

The Anderson family is preparing for a family reunion. They think they will need 22 juice boxes for every 6 children who attend. How many juice boxes will they need if they are expecting 15 children?
Answer:
52
Step-by-step explanation:
26 divided 4 multiplied by 8 equals 52
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
1 children = 22/6 juice boxes
15 children = 55 juice boxes
The number of juice boxes that are needed for 15 children is
55 juice boxes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
They think they will need 22 juice boxes for every 6 children who attend.
This can be written as,
6 children = 22 juice boxes
Divide 6 on both sides.
1 children = 22/6 juice boxes
Multiply 15 on both sides.
15 children = 15 x 22/6 juice boxes
15 children = 5 x 11 juice boxes
15 children = 55 juice boxes
Thus,
The number of juice boxes that is needed for 15 children is
55 juice boxes.

Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets for $25. The venue has the capacity to hold 400 people. The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise at least $5,000 for her school
What is the minimum number of pre-sale tickets she needs to sell to make her goal?
333
66
67
Answer:
67
Explanation:
Let us assume that Anna sells x number of pre-sale tickets and y number of at-the-door tickets.
Since, total capacity of the venue is 400, so we can write x + y = 400 ...... (1)
Now, given that each pre-sale ticket costs $10 and each at-the-door ticket costs $25, and the total funds she needs to raise is $5000
So, we can write 10x + 25y = 5000, ⇒ x + 2.5y = 500 .... (2)
Now, solving equations (1) and (2) we get,
(2.5 - 1)y = 500 - 400 = 100
⇒ 1.5y = 100
⇒ y = 66.67
Hence, from equation (1) we get, x = 400 - 66.67 = 333.33
Since Y can't be a fraction and it can not be < 66.67 (Otherwise the goal of $5000 can not be achieved)
So, the minimum number of at-the-door ticket she needs to sell to make her goal is 67.
The minimum number of pre-sale tickets she needs to sell to make her goal are 333.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets for $25. The venue has the capacity to hold 400 people.
We can write the equations representing the given situation as -
10x + 25y = 5000 ....... Eq{1}
x + y = 400 ....... Eq{2}
where [x] represents the number of people who bought the pre-sale tickets for $10 and [y] represents the number of peoples who bought at-the-door tickets.
So, we can write -
x = (400 - y)
So, we can write -
10(400 - y) + 25y = 5000
4000 - 10y + 25y = 5000
15y = 5000 - 4000
15y = 1000
y = 66.67
So, we get -
x = 400 - 66.67
x = 333.34
x = 333 {approx.}
Therefore, the minimum number of pre-sale tickets she needs to sell to make her goal are 333.

As your question is missing some information, so after some research I was able to find the potential question you wanted to ask which is:
Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
So, I am going to answer you based on the complete question I was able to find, which anyways would clear your concept.
Answer:
The distance between A and B will be: [tex]\frac{3}{6}[/tex]
Step-by-step explanation:
From the question statement, it is clear that
Point A is located at negative 4 over 6 i.e. -4/6, and
point B is located at negative 1 over 6 i.e. -1/6.
As we know that we can determine the distance between two negative numbers on a given line by finding the distance by taking the absolute value of the difference between those numbers.
so,
Distance between A and B will be:
[tex]\left|-\frac{4}{6}-\left(-\frac{1}{6}\right)\right|=\left|-\frac{4}{6}+\frac{1}{6}\right|[/tex]
[tex]=\left|\frac{-4+1}{6}\right|[/tex]
[tex]=\left|-\frac{3}{6}\right|[/tex]
[tex]=\frac{3}{6}[/tex]
Hence, the distance between A and B will be: [tex]\frac{3}{6}[/tex]
point A is located at -2, 5
point B is located at 5,5
the distance is 7 units
pile of sand has weight of 90kg the sand is put into a small bag, medium bag and a large bag in the ratio 2:3:7
work out the weight of sand in each bag
Answer:
Sand in small bag = 2x = 2(7.5) = 15 kgSand in medium bag = 3x = 3(7.5) = 22.5 kgSand in a large bag = 7x = 7(7.5) = 52.5 kgStep-by-step explanation:
Total weight = 90 kg
As 90 kg has been distributed in 3 bags in the ratio 2:3:7
Let the small bag contains = 2x
Let the medium bag contains = 3x
Let the big bag contains = 7x
so the equation becomes
2x+3x+7x = 90
12x = 90
x = 90/12
x = 7.5
Thus,
Sand in small bag = 2x = 2(7.5) = 15 kgSand in medium bag = 3x = 3(7.5) = 22.5 kgSand in a large bag = 7x = 7(7.5) = 52.5 kgSOLUTION CHECK
15+22.5+52.5=90 kg

4. Find the sum of the first eighteen terms of the arithmetic sequence whose nth
term is an = 15 + 8n.
a. 1438
b. 1638
c. 1836
d. 1783
Answer:
The sum of first eighteen terms of the arithmetic sequence is [tex]\mathbf{S_{18}=1638}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to find the sum of the first eighteen terms of the arithmetic sequence whose nth term is an = 15 + 8n
The formula used to calculate sum of arithmetic sequence is: [tex]S_n=\frac{n}{2}(a_1+a_n)[/tex]
Finding a₁ by putting n=1
[tex]a_n=15+8n\\a_{1}=15+8(1)\\a_{1}=15+8\\a_{1}=23[/tex]
We have [tex]a_1=23[/tex]
Finding 18th term n=18
[tex]a_n=15+8n\\a_{18}=15+8(18)\\a_{18}=15+144\\a_{18}=159[/tex]
So, the sum of first eighteen terms of the arithmetic sequence is:
[tex]S_n=\frac{n}{2}(a_1+a_n)\\S_{18}=\frac{n}{2}(a_1+a_{18})\\S_{18}=\frac{18}{2}( 23+159)\\S_{18}=9(182)\\S_{18}=1638[/tex]
So, the sum of first eighteen terms of the arithmetic sequence is [tex]\mathbf{S_{18}=1638}[/tex]

Mary has $65,000 to invest in two accounts. The first account is a private savings offering 6% annual interest and the second account is a government savings account offering 4% annual interest. How much money should Mary invest in each account to make $3520 in total annual interest.
Answer:
first account with 6% interest ( x ) = $46000
second account with 4% interest ( y ) = $19000
Step-by-step explanation:
Principal = $65000
first interest rate = 6%
second interest rate = 4%
assuming ; X = money invested in first account , Y = money invested in second account
hence :
( 65000 - y ) * 6% + ( 65000 - x ) * 4% = 3520
3900 - 0.06 y + 2600 - 0.04 x = 3520
0.04 x + 0.06 y = 3900 + 2600 - 3520
0.04 x + 0.06 y = 2980 ----- ( 1)
x + y = 65000 ------- ( 2 )
solve equation 1 and 2 simultaneously by elimination method
0.04 x + 0.06 y = 2980 ------ ( 3 )
0.06 x + 0.06 y = 3900 ------- ( 4 )
subtract equation 3 form equation 4
0.02 x = 920 , hence x = $46000
therefore y = $65000 - $46000 = $19000
Solve for X. x/7 + 9/1= 15

Mark wants to get at least a 90% for his marks in his science class. So far, he has
taken five 100-points tests, and he scored 460 points total. The final test is 150
points. What must he score to finish the class at his goal of at least 90%?
Answer:
[tex]x\geq 125[/tex]
Step-by-step explanation:
So first we have to find out the total number of points possibleSo he took 5 tests each with a max score of 100 points, so that's 500 points totalThe final test will be 150 points, so his whole grade is out of 500+150= 650 pointsHe has already scored 460 of those 650 pointsNow how much must he get in the least, on the last test in order to make 90%?Now we need to find what 90% of 650 points isso [tex]\frac{90}{100} *650=\frac{90*650}{100} =585points[/tex] Then we ask ourselves, how much must we add to 460, to get 585 points? 585-460= 125 pointsSo Mark needs to get either 125 points or more on the next test to make 90% or moreNow let's say the letter [tex]x[/tex] means whatever grade number Mark gets on his next testThis number must not be less than 125, so it must be either equal to or greater than 125 pointsSo [tex]x\geq 125[/tex]
