A line passes through the point (6, -8) and has a slope of -3/2
Write an equation in slope-intercept form for this line.

Answers

Use y=mx + b, which is slope intercept form

b = y intercept(when x=0)
m = slope

You need to find the y intercept. Use your coordinates and substitute it in the slope intercept equation.

we use (6, -8)

y = mx + b

Then, -8 = -3/2(6) + b

-8 = -9 + b
1 = b

Thus,

y = -3/2x + 1

Step-by-step explanation:

m = slope = (difference in y)/(difference in x)

m = (5 - 1)/(-5 - (-2))

m = 4/(-5 + 2)

m = -4/3

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

Answers

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 kg

Step-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 kg

SOLUTION CHECK

15+22.5+52.5=90 kg

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.

Answers

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

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

Answers

Answer:

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.

Find the number if 5/6 of it is 55.

Answers

Answer:

The unknown number is 66.

Step-by-step explanation:

We know that we need to find the number that is 55 when calculated as 5/6 or the whole number. First, we must divide 55 by 5.

55 ÷ 5 = 11

This means that 1/6 of the unknown number is 11.

Now, let's multiply 11 by 6.

11 x 6 = 66

Therefore, the unknown number is 66.

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

Shaq invested $900 into a savings account that pays annual simple interest. At the end of 9 years, he earned $461.70 in interest. What is the interest rate on the savings account? Round to the nearest tenth of a percent.

Answers

Answer:

Interest = $900 * x * 9 years with "x" = interest rate

If interest = 461.70 then

461.70 = 900 * 9 * x

x = 461.70 / 8,100

x = interest rate = .057 = 5.7%

Double Check

Interest rate of 5.7 per cent equals

.057 * 900 = $51.30 per year

Nine Years = 9 * 51.30 equals 461.70

So, it's correct!!!
