Answer:

slope = - 7

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, - 6) and (x₂, y₂ ) = (2, 15)

m = [tex]\frac{15+6}{2-5}[/tex] = [tex]\frac{21}{-3}[/tex] = - 7

Answer:

2744 Rhinos left

Step-by-step explanation:

Given that,

There are 4,000 Rhinos left in the world i.e. initial amount of Rhinos, A₀ = 4,000

They are going extinct at a rate of 3.7% each year.

We need to find no of Rhinos left in 10 years. For this, we will use exponential decay rate equation as follows :

[tex]A(t) = Ao(1 - r)^t[/tex]

Here, A₀ = 4,000, r = 3.7% = 0.037, t = 10 years

Putting all the values, we get :

[tex]A(t) = 4000\times (1 - 0.037)^{10}\\\\=2743.61[/tex] (we can use calculator to find it)

A(t) = 2744 Rhinos

Hence, 2744 Rhinos will be left after 10 years.

The midpoint formula is (x2 + x1)/2 , (y2 + y1)/2 = x_mid,y_mid

y_mid = 1

x_mid = -1

y2= 4

x2 = 2

Solution

(2 + x1)/2 = -1

(2 + x1) = -1 * 2

2 + x1 = -2

x1 = -2 -2

x1 = - 4

====================

(4 + y1)/2 = 1

4 + y1 = 2

y1 = 2 - 4

y1 = -2

Answer:

Let the measures of three angles be 2x, 9x, 4x

Sum of the angles of a triangle = 180

2x+9x+4x = 180

15x = 180

x = 180/15 = 12

First angle = 2x = 2*12 = 24°

Second angle = 9x = 9*12 = 108°

Third angle = 4x = 4*12 = 48°

Answer:

Step-by-step explanation:

Her profit will increase be 6 dollars.  

x = 1

y = 45(1)

y = 45  

The number of more dollars earned by Amanda if she switched to new icing will be $6.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties

Given that Amanda sells homemade birthday cakes for a profit of $39 per cake. She is considering switching to a new type of icing that will increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit.

The number of dollars will be calculated as,

y = 45x

For 1 cake the profit with new icing is,

y = $45

The more number in profit is calculated as,

P = 45 - 39

P = $6

Therefore, the number of more dollars earned by Amanda if she switched to new icing will be $6.

Answer:

Step-by-step explanation:

What is the equation?

You need to replace all A with 3 and all c with 12. If I had the equation, I'd be glad to help further.

For the given values a=3 and c=12 the required expression is 4a-c=0.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

The value of a = 3         (1)

And the value of c = 12       (2)

To determine the expression,

divide equation (1) and equation (2),

a/c = (3/12)

⇒a/c = 1/4

⇒4a=c

⇒4a-c = 0

The required expression is 4a-c=0.

Answer:

28+14.50+524.50+13.25=  580.25

Step-by-step explanation:

Add it all together.

The expression that represents the total cost for both the membership after m months is

552.50 + 27.75m

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Internet service:

Charges = $28

Monthly pay = $14.50

Total cost after m months.

= 28 + 14.50m

Movie streaming:

Joining = $524.50

Monthly charge = $13.25

Total cost after m months.

= 524.50+ 13.25m

The total cost for both memberships after m months.

= 28 + 14.50m + 524.50 + 13.25m

=  552.50 + 27.75m

Thus,

The total cost is 552.50 + 27.75m.
