PLS HELP 100 pointsGiven the equation −4square root of x minus 3 = -12, solve for x and identify if it is an extraneous solution.

Answers

Answer 1

Answer:

x=4 17/64

Step-by-step explanation:

-4(sq rt x)-3=-12

simplify

-4(sq rt x)-3+3=-12+3

-4(sq rt x)=-9

-4(sq rt x)/-4=9/-4

sq rt x=-9/4

x=-9/4 x -9/4=81/16

x=4 17/64 or 4.27

Answer:

they should get 8/3 each but because of your question the answer lies between 2 and 3

Step-by-step explanation:

if 3 cats and 8 once then 8 divided by 3 is 8/3 which is about 2/6667 then that is between 2 and 3. Done!

You simply divide the 8 ounces of cat food between the 3 cats, so we have 8\3 which is equal to 2.66 therefore our answer lies between the whole numbers 2 and 3.

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.

Answers

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50

7.50 - 3= $4.50

9.00+7.47+4.50= $20.97

Step-by-step explanation:

Solve 2( 4x - 1) = 18

Answers

the answer is 2.5

2 (4x - 1) = 18
8x - 2 = 18
8x = 20
x = 2.5

Answer:

x=2

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

What are the types of solutions of a system f linear equations?

If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.

There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.

Given, A linear system,

5x - 2y = 3...(1) and 3x - y = 4...(2)

Now, To eliminate one of the variables 'x' or 'y' we can apply arithmetic operations to the linear operations.

Now, If we Multiply the second equation by - 2 and then add the result to the first equation we'll have,

The stock price for fwt was $42.61 in October. In November the stock had increased 7%, but in December the price fell by 7%. What was the price of fwt stock in December? Round your answer to the nearest cent, if necessary.

Answers

Answer:

$42

Step-by-step explanation:

The computation of the price of fwt stock in december is shown below:

In November, it would be

= Stock price in October × (1 + 0.07)

= $42.61 × 1.07

= $45.5927

In December it would be

= $45.5927 × (1 - 0.07)
