The heartbeat of a horse is about 42 beats per minute. About how many times would it beat in ten minutes?

A. 400 beats

B. 450 beats

C. 475 beats

D. 500 beats

The number of **heartbeat **in ten minutes is 420 beats

**Unit rates **are the rates of a quantity to one of another quantity

From the question, the given parameters are:

Number of heartbeats per minute = 42 beats per minute -- this represents theThe number of **heartbeats **in these ten minutes is then calculated as

Total heartbeats = Number of heartbeats per minute x Number of minutes

Substitute the known values in the above equation

So, we have

Total heartbeats = 42 x 10

For the function f(x) =[tex]\sqrt{8x+10}[/tex] the inverse function [tex]f^{-1}[/tex](x) = [tex]\frac{x^2-10}{8}[/tex] x≥ 0 as can be calculated through the **inverse function**'s formula.

In mathematics, any kind of inverse is a function that serves to “undo” any other function. That is, if f(x) produces y, then while putting y into the inverse off it produces the output x.

How do you find the inverse of a function?To find the inverse of a function, write the function y as a function of x i.e., y = f(x) and then solve for x as a function of y.

What is inverse example?Inverse operations are seen as opposite operations that provides undo to each other. For example, 5 ✕ 2 = 10 and 10 ÷ 2 = 5 are **inverse operations.**

Every one-to-one function f has an inverse; this inverse is denoted by f−1 and read aloud as 'f inverse'. A function and its inverse 'undo' each other: **one function** does something, the other undoes it.

Answer is

Y = 4 5/7

G = 3 5/7

Step by step

We have 4 Y = yellow circles

We have 3 G = green butterflies

Our equations are

4Y + 3G = 30

G= Y - 1 (because there is 1 less green butterfly than yellow circle)

To solve for Y, substitute G value for G

4Y + 3(Y - 1) = 30 distribute

4Y + 3Y - 3 = 30 combine

7Y -3 = 30 add 3 to both sides

7Y = 33 divide both sides by 7

Y = 4 5/7

To solve for G, substitute Y value for Y

4( 4 5/7) + 3G = 30 distribute

18 6/7 + 3G = 30 subtract 18 6/7 from both sides

3G = 30 - 18 6/7

3G = 11 1/7 divide both sides by 3

G = 3 5/7

Check your work

Sun your Y and G values into your equation

G = Y - 1

3 5/7 = 4 5/7 - 1

3 5/7 = 3 5/7

Yes, they equal so it’s true!

Y = 4 5/7

G = 3 5/7

Problem solved

Y = 4 5/7

Step by step

We have 4 Y = yellow circles

G= Y - 1 (because there is 1 less green butterfly than yellow circle)

To solve for Y, substitute G value for G

4Y + 3(Y - 1) = 30 distribute

4Y + 3Y - 3 = 30 combine

7Y -3 = 30 add 3 to both sides

Y = 4 5/7

To solve for G, substitute Y value for Y

4( 4 5/7) + 3G = 30 distribute

What are the new vertices of quadrilateral KLMN if the quadrilateral is translated two units to the right and four units upward? A. K = (-2,0), L' = (1,0), M = (1,-3), N = (-2,-3) B. K = (-2,-2), L' = (1,-2), M = (1,-5), N = (-2,-5) C. K = (-0,0), L' = (3,0), M = (3,-1), N = (0,-1) D. K = (-2,2), L' = (1,2), M = (1,-1), N = (-2,-1)

**K' ( -2, 2) , L' (1,2) , M' (1,-1) , N' (-2,-1)**

Firstly, we needt to identify the coordinates of the vertices of the quadilateral

Afterwards, we then perform the translation

The translation simply means we add 2 to the x-value and add 4 to the y-value

So if we had coordinates of a vertex as (x,y); upon translation, we will have (x + 2, y+ 4)

Let us identify the vertices;

Choose the best initial step in solving the following system by substitution.

2x + 3y = –12

6x + y = 18

Answers:

1.Solve the first equation for x.

2.Solve the first equation for y.

3.Solve the second equation for x.

4.Solve the second equation for y.

Using **substitution method**, the best initial step in solving the equation is solve the first equation for x.

The equation can be solved by **substitution method** as follows:

2x + 3y = -12

6x + y = 18

Hence, let's make y the subject of the formula in **equatio**n(ii)

6x + y = 18

y = -6x + 18

We have to** substitute** the value of y in equation(i)

2x + 3y = -12

2x + 3(-6x + 18) = -12

2x - 18x + 54 = -12

- 16x + 54 = -12

-16x = - 12 - 54

- 16x = -66

x = 66 / 16

x = 33 / 8

Therefore,

6(33 / 8) + y = 18

99 / 4 + y = 18

y = 18 - 99 / 4

y = - 27 / 4

From the solving above the best step to solve the** equation** is solving the first **equation** for x.

A northbound train and a southbound train meet each other on parallel tracks heading in opposite directions. The northbound train travels 12 miles per hour faster than the southbound train. After 2 hours, they are 240 miles apart. At what speeds are the two trains traveling?

please help me, I'm gonna fail my test tomorrow

**Answer:**

Speed of northbound train = 66

Speed of southbound train = 54

**Step-by-step explanation:**

First, let's make the variables simpler:

Speed of southbound train = x

Thus:

Speed of northbound train = y = x + 12

Distance = speed · time

240 = 2 ( x + x + 12 ) = 2 ( 2x + 12 ) = 4x + 24

216 = 4x

x = 54

Now, plug in x to find the speed of the northbound train (y):

y = 54 + 12 = 66
