Extraneous solutions are untrue solution of an equation

Mike does not obtain any extraneous solutions

The equation is given as:

[tex]\sqrt{z^2+2z-3}=z-3[/tex]

When squared, it becomes

[tex]z^2+2z-3=z^2-6z + 9[/tex]

Evaluate the like terms

[tex]2z-3=-6z + 9[/tex]

Collect like terns

[tex]6z + 2z = 9 + 3[/tex]

Evaluate the like terms

[tex]8z = 12[/tex]

Divide through by 8

[tex]z = 1.5[/tex]

Substitute 1.5 for z in the given equation

[tex]\sqrt{z^2+2z-3}=z-3[/tex]

[tex]\sqrt{1.5^2+2*1.5-3}=1.5-3[/tex]

Evaluate

[tex]\sqrt{2.25}=-1.5[/tex]

Determine the square root of 2.25

[tex]-1.5=-1.5[/tex]

Hence, Mike does not obtain any extraneous solutions

Answer:

$15339.66

Step-by-step explanation:

Let's start with what we know,

1 classroom = 1 set of speakers

1 set of speakers = $365.23

The school has 42 classrooms

Find how much it will cost to place the speakers in all of the classrooms

To find the amount it will cost, you will need to substitute values

1 school = 42 classrooms

              = 42 sets of speakers

              = 42 (365.23)

              = 15339.66

It will take $15339.66 to place the speakers in all of the classrooms at the school.

Answer:

Step-by-step explanation:

Linear equation form:  y = mx + b

(where m is the slope and b is the y-intercept)

The rate of change for a line is the slope.

Function 1:  y = 6

⇒ the slope is zero so the rate of change is zero

Function 2:  y = 2x + 7

⇒ the slope is 2 so the rate of change is 2

Therefore, 2 - 0 = 2

So the rate of change of function 2 is 2 more than the rate of change of function 1

Answer:

150

Step-by-step explanation:

So I will shorten Eric, and Bob's names as E, and B.

So the equations are this

B-E = B+E - 240, E as Eric, and B as Bob, and this E+B=9(E-B)

Move the variables and you get

-2E =- 240

Just divide them both by -2

and E=120

So when we know the value of E we can just plug it into the 1st question

120+B=9B+1080

Moves the Variables and numbers to the other side

8B=1200

1200/8= 150

B=150

There is Bob's weight

Answer:

b = -20

Step-by-step explanation:

Let's start by finding the slope of the line.

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Origin: (0, 0)

We can use (0, 0) and (3, 5) to find the slope:

[tex]Slope=\frac{5-0}{3-0}=\frac{5}{3}[/tex]

Then, we can plug this into the equation for slope to find the value of b (the slope has to be the same, since they're on the same line)

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{5}{3}=\frac{b-5}{-12-3}\\\frac{5}{3}=\frac{b-5}{-15}\\\text{Multiply both sides by -15}\\\frac{5}{3}(-15)=b-5\\\frac{-75}{3}=b-5\\-25=b-5\\\text{Add 5 to both sides}\\b=-20[/tex]

Answer:

6.875 or 6 7/8

Step-by-step explanation:

Because first we add the whole numbers 3 + 3=6

So we have 6 holes.

Now sense our demionters are not the same were going to try to get 4 to 8 so x 2.

sense we times the denominator on 1/4 we have to times 1 by 2 also.

so so now our 1 is a 2.

Next were going to add 2 + 5=7 so out fraction is 6 holes and 7/8

The reason i also said 6.875 is because 7/8=0.875 or 87.5%

So fraction form =6 7/8

decimal form=6.875

And percent form=87.5%

Hope this helps have a great afternoon:)

11/12 - 1q/6 + 5q/6 - 1/3

= 11/12 - 1/3 + 5q/6 - 1q/6

= 11/12 - 4/12 + q/6(5 - 1)

= (11 - 4)/12 + 4q/6

Hey!

Let's see... if they walk 10 feet in 6 seconds,  then they walk about half a foot a second (0.6 to be exact.)

Multiply 0.6 by 45 and your answer should be.. 27. So, they walk 27 feet in 45 seconds.

Next, we keep multiplying 0.6 by a number over 45, but under 100, and the total amount of time it takes for a penguin to was 45 feet is... 75!

We know this because 75x0.6 is 45. and 75 is the number of seconds it takes to walk 45 feet for the penguin.

Your answer for #1 is 27

Your answer for #2 is 75

The area of a circle as a function of the circumference when calculated from substituting values in their formulas gives the expression written as; A = πC²/4

The formula for area of a circle is;

A = πr²

Making area as a function of the radius will give;

r = √(A/π)

Formula for Circumference of a Circle is;

C = 2πr

Thus making Circumference as a function of the radius will give;

r = C/2

Putting C/2 for r in the area formula gives;

A = π(C/2)²

A = πC²/4
