The coordinates of the image of the point (4,5) after reflecting over the

the y-axis is (- 4, 5).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, A point (4, 5) is reflected over the y-axis.

We know points of coordinated (x, y) reflected over the x-axis becomes

(- x, y).

Therefore, The coordinate points (4, 5) after reflecting over the y-axis would be ( - 4, 5).

The equation for the number of beats per minute is 55 beats per minute

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of beats be = A

Now , the value of A = 220 beats

The total time required for Sam to have 220 beats = 4 minutes

So , the number of beats of Sam in 1 minutes is calculated by

The equation will be

The number of beats of Sam in 1 minutes is = total number of beats  / total time required for Sam to have 220 beats

The number of beats of Sam in 1 minute is = 220 / 4

The number of beats of Sam in 1 minute is = 55 beats per minute

Therefore , Sam would have 55 beats every minute or 55 beats per minute

And for the period of 4 minutes , Sam would have

Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4

Number of beats for 4 minutes = 55 x 4

Number of beats for 4 minutes = 220 beats in 4 minutes

Hence , The equation for the number of beats per minute is 55 beats per minute

Answer:

Step-by-step explanation:

-34x+6=-28

       -6     -6

-34x=-34

-34     -34

x=1

Subtract 6 from both sides. on the left the 6 will be canceled out and on the right -28-6= -34

Than you divide -34 on both sides on the left the -34 will be canceled and on the right -34 divided bt-34 is positive 1. So x equals 1.

Answer:

Your answer is x = 11/17

Step-by-step explanation:

I gotchu!

Alright first, subtract 6 on both sides. After doing so, your equation should look like:

-34x = + 22

Then, divide -34 on both sides. Do not divide x though! The equation will look like:

x= -22/34

Now, let's simplify the answer. We can divide 22 and 34 by 2 so we will do that.

After simplifying, it should be 11/17.

Finally, keep it improper because you always should keep fractions improper when doing this.

Your answer is x = 11/17

Let's solve your equation step-by-step

2.4(x-6)=-5.6x+8

Step 1: simplify both sides of the equation

2.4(x-6)=-5.6x+8

(2.4)(x)+(2.4)(-6)=-5.6x+8 (distribute)

2.4x+-14.4=-5.6x+8

2.4x-14.4=5.6x+8

Step 2: Add 5.6x to both sides.

2.4x-14.4+5.6x=-5.6x+8+5.6x

8x-14.4=8

Step 3:Add 14.4 to both sides

8x-14.4+14.4=8+14.4

8x=22.4

Step 4 : Divide both sides by 8

8x/8 =22.4/8

2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

A proportional relationship between variable y and x can be expressed as:

y = kx

k is the unit rate/constant of proportionality.

k = y/x

Thus, find the equation for the table and the graph respectively in order to determine which equation represents the lower unit rate.

Equation for the table using a pair of coordinates, say (11, 2):

Find, unit rate (k) by substituting x = 11, and y = 2 into k = y/x

k = 2/11

Plug in the value of k = 2/11 into y = kx

The equation for the table is:

y = 2/11x

Equation for the graph using a point on the line, say (9, 2):

Find, unit rate (k) by substituting x = 9, and y = 2 into k = y/x

k = 2/9

Plug in the value of k = 2/9 into y = kx

y = 2/9x

In conclusion, 2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

The simplest radical form is [tex]9\sqrt{5}[/tex] ⇒ (c)

Step-by-step explanation:

To simplify any square root;

Examples:

1. Simplify [tex]\sqrt{8}[/tex]

factorize 8 using prime numbers

8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]

Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]

2. Simplify [tex]\sqrt{18}[/tex]

factorize 18 using prime numbers

18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]

Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]

Let us simplify [tex]3\sqrt{45}[/tex]

∵ 45 = 3 × 3 × 5

Answer:

12 hours

Step-by-step explanation:

So we know that Jim makes $5 an hour and was given a one time bonus of $50. Using the information given, we can make the expression:

5h + 50

to represent how much Jim makes in h hours.

Now we also know that Sarah makes $8 an hour and was given a one time bonus of $14. Using this information, we can make the expression:

8h + 14

to represent how much Sarah makes in h hours.

Now to find how many hours it will take for their paychecks to be the same, we have to set the two expressions equal to each other and solve for h:

8h + 14 = 5h + 50

Now solve for h. Subtract 5h from both sides.

3h + 14 = 50

Subtract 14 from both sides.

3h = 36

Divide both sides by 3.

h = 12

So it will take 12 hours for their paychecks to be the same.

System of Linear Equations entered :

 [1]           -2y-3y+z=-6

 [2]           x+y-z=5

 [3]           7x+8y-6z=31

Equations Simplified or Rearranged :

  [1]    -5y + z = -6

  [2]    y - z + x = 5

  [3]    8y - 6z + 7x = 31

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -y + z + 5

// Plug this in for variable  x  in equation [3]

  [3]    8y - 6z + 7•(-y +z +5) = 31

  [3]    y + z = -4

// Solve equation [3] for the variable  z

 [3]    z = -y - 4

// Plug this in for variable  z  in equation [1]

  [1]    -5y + (-y -4) = -6

  [1]    -6y = -2

// Solve equation [1] for the variable  y

  [1]    6y = 2

  [1]    y = 1/3

// By now we know this much :

   y = 1/3

   z = -y-4

   x = -y+z+5

// Use the  y  value to solve for  z

   z = -(1/3)-4 = -13/3

// Use the  y  and  z  values to solve for  x

 x = -(1/3)+(-13/3)+5 = 1/3

Solution :

{y,z,x} = {1/3,-13/3,1/3}
