What is the slope of the line that passes
through the points (-4, 4) and (-1, 3)?
Write your answer in simplest form.

it's A and D good luck

Answer:

A., D.

Step-by-step explanation:

Let t = number of two-point questions.

Let f = number of four-point question.

First we deal with the number of questions.

There are 42 questions. All the questions are either 2-point questions or 4-point questions.

t + f = 42

Now we deal with the number of points.

t two-point questions are worth 2t points.

f four-point questions are worth 4f points.

Altogether, they are worth 2t + 4f points.

The total number of points is 100, so

2t + 4f = 100

The system of equations has the equations:

t + f = 42

2t + 4f = 100

Answer: A., D.

The value of x in the coordinates (-12,1) and (x,7), having a slope of 1/8 is 36.

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given that;

Point 1 (-12,1)

Point 2 (x,7)

Slope m = 1/8

Plug the values into the slope formula and solve for x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

1/8 = ( 7 - 1 )/( x - (-12) )

1/8 = ( 6 )/( x + 12)

Cross multiply

( x + 12) = 6 × 8

x + 12 = 48

x + 12 - 12 = 48 - 12

x = 36

Therefore, the value of x is 36.

The work done in pulling the rope up 10 ft is 864 ft-lbs, calculated by multiplying the rope's weight (72 lbs) by the distance (10 ft) it was lifted.

Work done = Weight x Distance

Work done = 72 lbs x 10 ft

Work done = 720 ft-lbs

Additional work done for weight of rope = Weight of rope x Distance

Additional work done for weight of rope = 90 x 10

Additional work done for weight of rope = 900 ft-lbs

Total work done in pulling the rope up 10 ft = 720 ft-lbs + 900 ft-lbs

Total work done in pulling the rope up 10 ft = 864 ft-lbs

The work done in pulling the rope up 10 ft is calculated by multiplying the weight of the rope (72 lbs) by the distance (10 ft) it was lifted. This gives us a result of 720 ft-lbs. However, since the rope is 90 ft long, we must also take into account the additional weight of the rope beyond the 10 ft that was lifted. So, we multiply the weight of the rope (90 lbs) by the distance (10 ft) to get an additional work done of 900 ft-lbs. Adding the two results together gives us 864 ft-lbs of work done in pulling the rope up 10 ft. This shows that the heavier a rope is, the more work must be done to lift it.

Step-by-step explanation:

Lets say Bob has 17 strawberry, 19 Cola, and 4 blueberry, we can infer there is an equal amount of gumballs of each flavor in the machine; Before bob bought any gumballs there were 180 and if there were only 3 flavors we would divide 180 by 3 and get 60. That means each flavor has 60 of its own flavor and if we take 19 from the 60 cola flavored we can get 41.

The measure of exterior angle ACD is 132°

The exterior angle theorem states that whenever a triangle's side is extended such that it creates another exterior(outside angle), the resultant exterior angle created is equal to the sum(addition) of the other two opposite (inner) interior angles of the triangle.

From the information given:

Angle A = 50; Angle B = 4x + 2, Angle ACD = 6x + 12

Therefore;

50 + 4x + 2 = 6x + 12

As per unitary method, it will take 9 years for the man to be three times as old as his son.

The unitary method is a mathematical technique that involves finding the value of a single unit, and then using that unit to find the value of a larger quantity.

First, let's define our variables:

Let the man's age be M

Let the son's age be S

According to the problem, we know that:

M = 42

S = 12

We want to find out how many years it will take for the man's age (M) to be three times his son's age (S). Let's call this number of years "y".

Using the unitary method, we can set up the following equation:

M + y = 3(S + y)

Here's what this equation means:

M + y represents the man's age after y years

S + y represents the son's age after y years

3(S + y) represents three times the son's age after y years

We can simplify this equation by distributing the 3:

M + y = 3S + 3y

Next, we can isolate the variable y (which represents the number of years we're trying to find) by moving all the other terms to the opposite side of the equation:

y - 3y = 3S - M

Simplifying this, we get:

-2y = 3S - M

Finally, we can solve for y by dividing both sides by -2:

y = (M - 3S) / -2

Plugging in the values we know, we get:

y = (42 - 3(12)) / -2

y = 9

Plan B will save you money for a 1-day rental if you drive more than 166.67 miles.

To determine the range of miles for which Plan B will save money over Plan A for a 1-day rental, we need to set up an equation that compares the total cost of each plan.

For Plan A, the cost is given by:

Cost(A) = 30 + 0.12x

where x is the number of miles driven.

For Plan B, the cost is given by:

Cost(B) = 50

since there is no additional charge for mileage.

To determine the range of miles for which Plan B is cheaper than Plan A, we need to find the value of x for which:

Cost(B) < Cost(A)

Substituting the expressions for the costs of each plan, we get:

50 < 30 + 0.12x

Simplifying this inequality, we get:

The measure of angle ACD for the given circle is 67.5 degree.

A triangle is inside a circle when a circle encircles it, and each vertex of the triangle touches the circle.

When a circle encircles a triangle, the triangle lies outside the circle and the circle makes one point contact with each of the triangle's sides. The triangle's sides are perpendicular to the circle.

Given that,

The inscribed angle CDA = 1/2(arc AC).

arc AC = 90 degree.

Then:

∠ CDA = 90 / 2

∠ CDA = 45

Triangle ACD is isosceles, so:

∠ ACD + ∠ CAD + ∠ CDA = 180 degree

Here, ∠ ACD = ∠ CAD

∠ ACD + ∠ACD + ∠ CDA = 180 degree

∠ ACD = 180-45 / 2

The profit generated from selling x boxes of pencils is a linear function of x, with a slope of $0.80 and a y-intercept of -$12.60

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the range) with the property that each input is related to exactly one output.

Let us first define the demand function as D(x), where x is the number of boxes of pencils sold. We know that the manager can sell 10 boxes of pencils at a price of $2.19 per box, which means that the revenue generated from this sale is:

10 * $2.19 = $21.90

Similarly, when the price is $1.70, she can sell 24 boxes of pencils, which gives a revenue of:

24 * $1.70 = $40.80

Now, we can use these two data points to find the equation of the demand function. Since we assume that the demand is linear, we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept. In our case, y represents the revenue generated by selling x boxes of pencils.

To find the slope, we use the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) and (x₂, y₂) are the two data points we have.

m = ($40.80 - $21.90) / (24 - 10)

m = $18.90 / 14

m = $1.35

To find the y-intercept, we can use either of the two data points and solve for b:

$21.90 = $1.35 * 10 + b

b = $7.40

Therefore, the demand function for the pencils is:

D(x) = $1.35x + $7.40

This means that for each additional box of pencils sold, the revenue generated increases by $1.35. The y-intercept of $7.40 represents the revenue generated when no pencils are sold, which includes fixed costs such as rent, utilities, and wages.

We also have the cost function C(x) = 0.55x + $20, which represents the total cost of buying x boxes of pencils. The profit function P(x) is defined as the difference between the revenue and the cost:

P(x) = D(x) - C(x)

Substituting the expressions for D(x) and C(x), we get:

P(x) = ($1.35x + $7.40) - (0.55x + $20)

Simplifying this expression, we get:

P(x) = $0.80x - $12.60

The correct answer choices for Z and X are $25.08 and $3.72, respectively.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

How to solve for this

To solve for Z and X simultaneously, you can use the following equation: Z + X = 59.5

You can then compare the four given answer choices for Z and X to determine which ones satisfy the equation.

For example, $1.51 + $22.35 = $23.86, which is not equal to 59.5, so neither of these answer choices is correct.

However, $25.08 + $3.72 = $28.80 which is equal to 59.5, so the correct answer choices for Z and X are $25.08 and $3.72, respectively.
