Find the slope of the line passing through the points (8,-4) and (-6,-3).

Anybody know this ?

**Answer:**

= -1/14

**Step-by-step explanation:**

We can use the slope formula

m = ( y2-y1)/(x2-x1)

= ( -3 - -4)/( -6 -8)

= ( -3+4)/( -6-8)

1/-14

= -1/14

A rectangle has a length of 2x+1 and a width of 3x-2.

Write an expression for the area of the rectangle.

**Answer:**

(2x+1)x(3x-2)

area of rectangle = length * width

length = 2x+1

width = 3x-2

area = (2x+1) x (3x-2)

What is the value of the expression -7+-4

-11 cuz 7+4 is 11 and since they both negative, 11 will be negative

**Answer:**

-11

**Step-by-step explanation:**

This is the answer because:

1) First, multiply the negative sign with the positive sign.

Negative x Positive = Negative

Equation: -7 - 4

2) Now, multiply the negative sign with the negative sign.

Negative x Negative = Positive

Equation: 7 + 4 = 11

3) Finally, add the greater number's sign (-7) in front of the number.

-11

she drank 14 ounces of her water, she has 28 ounces left, just divide 42 by 3

**Answer:**

1)14oz

2)28oz

**Step-by-step explanation:**

1) To find the amount of water is left in the bottle you want to substract 1/3 so the first thing you want to do is find what 1/3 of 42 is. So do this: (This is also 42/3)

42*1/3=14

So we now know that 14 is 1/3 of 45 which is the first answer. To find the second answer you want to substract 14 from 42 which is 28.

So that means she has 28 oz of water left when she gets there.

In a group of 80 people, 50 can speak Nepali, 45 can speak English and 7 of them do not

speak both languages.

a) Find the number of people who speak both languages.

b) Also illustrate the above information in Venn diagram.

**Answer:**

Universal set is 80

Number of people that speak Nepali is 50

Number of people that speak English is 45

Number of people that do not speak both is 7

a. Number of people that speak both languages is 22

b. As above

**Step-by-step explanation:**

a. Let make number of people that speak both languages x

To get x

(50-x) + (45-x) + x + 7 = 80

(50-x) + (45-x) + x = 80 - 7

(50-x) + (45-x) + x = 73

Open bracket

50-x+45-x+x= 73

50+45-2x+x = 73

95 - x = 73

-x = 73 - 95

-x = -22

x = 22

Therefore, number of people that speak both languages is 22

b. To get venn diagram

Number of people that speak Nepali is 50 - 22 = 28

Number of people that speak English is 45 - 22 = 23

Therefore, total = 28+23+22+7 = 80

Olga has $40 in her wallet. She has one more $5 bill than $10 bills, and two more $1 bills than $5 bills. If Olga has only three types of bills, how many bills of each denomination does she have?

**Answer:**

Number of $10 bills = 2

Number of $5 bills = 3

Number of $1 bills = 5

**Step-by-step explanation:**

**Given:**

Total amount = $40

Number of $10 bills = x

Number of $5 bills = x + 1

Number of $1 bills = x + 1 + 2 = x + 3

**Find:**

Number of each bills

**Computation:**

10(x) + 5(x+1) + 1(x+3) = 40

10x + 5x + 5 + x + 3 = 40

16x = 32

x = 2

**Number of $10 bills = x = 2**

**Number of $5 bills = x + 1 = 3**

**Number of $1 bills = x + 3 = 5**

**Answer:**

# of $10 bills = 2

# of $5 bills = 3

# of $1 bills = 5

The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid

ounces of volume. Express this density in ounces per liter. Round your answer to the

nearest whole number.

**Answer:**

701 ounces per liter

**Step-by-step explanation:**

it's from delta math

The required **density **in **ounces **per liter is 140 **onces **per liter.

The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid ounces of volume.

To determine density in ounces per liter.

**Volume **is defined as the **ratio **of the **mass **of an object to its density.

As given that, t weighs 5 kilograms for every 8.5 fluid ounces of volume.

1 KG = 7.0474 ounces

5kg = 35.247

8.5 fluid of ounces = 0.251 liter

Density is given as,

= mass / volume

= 35.274 / 0.251

= 140 ounces per liter.

Thus, the required **density **in **ounces **per **liter **is s140 ounces per liter.

Since the person earns over $30,000, they will be charged 20% on $30,000 plus 40% on ($47,000−$30,000)=$17,000. Hence the total amount of tax that they'd need to pay under the proposal is

Total Income Tax=$30,000×20%+$17,000×40%=$30,000×20100+$17,000×40100=$6,000+$6,800=$12,800.
