For the graphs you use the the method of

Rise(Up) / Run(Down) = Slope

for exmaple the first graph

The rise is 4 (up) and the run (down) is 6 so you divide that being 2/3 the slope.

For the secound part you use the formula

m= rise/run = y2-y1/x2-x1

for exmaple for number 7

(4,9) and (1,6) being (x1, y1) and (x2,y2)

so your rise is 3 and your run is 3 that being 3/3 = 1 so your slope is 1 or m=1

The perimeter of the triangle is given by an expression 18m³ + 2m² - m

Consider the following diagram.

In this question we have been given a triangle.

The sides of the triangles are represented by a mathematical expressions

(5m³ + 3m² - 2m), (8m³ - 4m² + 3m) and (5m³ + 3m² - 2m)

From given expression we can observe that, there are two sides with expression 5m³ + 3m² - 2m.

This means, the triangle must be an isosceles triangle.

We know that the formula for the perimeter of isosceles triangle.

P = 2a + b

where, a = side and b = base of isosceles triangle

Using above formula the perimeter of given triangle would be,

P = 2(5m³ + 3m² - 2m) + (8m³ - 4m² + 3m)

P = (10m³ + 6m² - 4m) + (8m³ - 4m² + 3m)

P = (10 + 8)m³ + (6 - 4)m² + (-4 + 3)m            .....(combine like terms)

P = 18m³ + 2m² - m

Based on the graph, it looks like the only y-value not used by the graph is –6.

The marked price when a customer gets a discount of 3250 (from graph) and the discount when the marked price is 2500

percentage, a relative value indicating hundredth parts of any quantity.

The relation between the market price and the discount is

y=0.5x

Which is the required relationship between the Marked Price and the Discount.

We have to find the marked price when a customer gets a discount of 3250

As discount is 3250

In the graph is represent the point F ( 3250, 0)

If we draw a line parallel to Y axis and passing through the point F( 3250, 0) then it intersects the line y = 2x at B( 3250 , 6500)

Accordingly we get the point A ( 3250, 6500)

Hence the Marked Price = 6500

Manually it can be checked

As discount is 3250

x = 3250

So y = 2 × 3250 = 6500

(2) We have to find the discount when the marked price is 2500

As marked price is 2500

In graph it represent the point C( 0, 2500)

If we draw a line parallel to X axis and passing through the point C( 0, 2500) then it intersects the line y = 2x at B( 1250 , 2500)

Accordingly we get the point B( 1250 , 2500)

Hence the discount = 1250

Manually it can be checked

As marked price is 2500

y = 2500

So x = 2500 ÷ 2 = 1250

Hence,  the marked price when a customer gets a discount of 3250 (from graph) and the discount when the marked price is 2500

For Jordan's pet grooming business to break even, he must groom 38 pets each month.

The break-even point describes a sales situation where the total costs equal the total revenue.

At the break-even point, there is no profit or loss.

Cost function: C = $15p + $1520

Revenue function: R = $55p

The total cost per month = C

The total revenue each month = R

The number of pets Jordan grooms monthly = p

To break even, C must be equal to R:

$15p + $1520 = $55p

15p + 1520 = 55p

-40p = 1,520

p = 38

Check:

Total costs = $15p + $1520

= $15(38) + $1520

= $570 + $1520

= $2,090

Total revenue = $55p

= $55(38)

= $2,090

Thus, grooming 38 pets each month, the total costs and revenue are equal to $2,090, respectively.

Answer: (7, -4)

Step-by-step explanation: To find the midpoint of a line segment, We take the average of the X-coordinates and the Y-coordinates of the two endpoints.

Given points A(4,-2) and B(10,-6), the midpoint can be found using the following steps.

1. Take the average of the X-coordinates: (4+10)/2=7.

2 Take the average of the Y-coordinates: (-2 + -6)/2=-4.

So the midpoint of the line segment joining A and B is (7,-4).

Step-by-step explanation:

You would use an inverse sine, if I'm not mistaken. You have the O (opposite) and the H (hypotenuse). With that you can do SOH - or sine. But since you want the angle, you do an inverse. So you do the inverse sine of O over H, or the inverse sine of 5/18. It gives you 16.128 degrees or so.

An equation that models the volume, V, of the cement in the container in terms of h is V = π[tex]r^2[/tex]h. The time at which the volume is 80π cubic feet is 6 minutes.

In the given question, we have to write an equation that models the volume, V, of the cement in the container in terms of h, then use the equation to determine the time at which the volume is 80π cubic feet.

The given radius r = 4 feet

Rate of filling the cylinder = 10 inches/minutes

Firstly we convert inches into feet.

As we know that;

1 inches = 1/12 feet. So

Rate of filling the cylinder = 10/12 feet/minutes

Rate of filling the cylinder = 5/6 feet/minutes

Height (h) in time 't' minutes = h = 5/6 t

Volume after t minutes

V = π[tex]r^2[/tex]h

Now putting the values

V = [tex]\pi\times(4)^2\times\frac{5}{6}t[/tex]

V = [tex]\pi\times16\times\frac{5}{6}t[/tex]

V = [tex]\frac{40\pi}{3}t[/tex]

As given that volume is 80π cubic feet.

Now, V = 80π

80π = [tex]\frac{40\pi}{3}t[/tex]

Multiply by 3 on both side, we get

240π = 40πt

Divide by 40π on both side, we get

t = 240π/40π

t = 6 minutes

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Now, According to the question:

Is a negative slope horizontal or vertical?

Negative slope means that as we move from left to right on the graph, the line falls. Zero slope means that the line is horizontal: it neither rises nor falls as we move from left to right. Vertical lines are said to have "undefined slope," as their slope appears to be some infinitely large, undefined value.

Hence, The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Answer: A. -2x² + 16x -29

Step-by-step explanation:

f(x) = x-4

g(x) = -2x² + 3

g(f(x)) = -2( x² + 16 -8x) + 3

         = -2x² - 32 + 16x + 3

         = -2x² + 16x -29

The situation can be modeled with the linear function:

f(x) = $30*x + $100

Evaluating that, we can see that after two years you will pay $820.

Here we know that you buy a gym membership for $100 plus $30 per month.

So, the cost after x months can be modeled by the linear function:

f(x) = $30*x + $100

Where x is the number of months and f(x) is the amount of money that you pay after x months.
