bazaltina [42]3 years ago
5 0

8[7 - (6x - 6)] + 6x  =  0          

 

8[7 - 6x + 6] + 6x  =  0            

56 - 48x + 48 + 6x  =  0        

 

104 - 42x  =  0                       .

 

- 42x  =  - 104                        .

 

x  =  52 / 21

x  ≈  2.476

How to find values of x that are not in the domain?
Mumz [18]
So the domain<span> is "all </span>x<span>". To </span>find<span> the </span>domain, I'll ignore the "x<span> + 2" in the numerator (since the numerator does </span>not<span> cause division by zero) and instead I'll look at the denominator. I'll set the denominator equal to zero, and solve. The </span>x-values<span> in the solution will be the </span>x-values<span> which would cause division by zero.</span>

A Blimp is 400 feet in the air. There is an angle of depression of 40 degrees to a football stadium. How far is the Blimp from t
VMariaS [17]

Answer:

Step-by-step explanation:

The diagram of the stadium and the blimp is shown in the attached photo. A right angle triangle, ABC is formed. Angle A is alternate to the angle of depression. This mean that they are equal. So angle A =40 degrees.

The distance of the the Blimp from the stadium is x feet which is the hypotenuse of the triangle.

Applying trigonometric ratio,

Sin 40 = 400/x

xsin40 = 400

x = 400/sin40 = 400 / 0.6428

x = 622.3 feet

Nine less than five times a number is equal to -30
disa [49]

To solve this question, we can start to set up an equation using what the question is telling us. Since we don't know what the number is, let's make it equal to x.

The phrase "5 times a number" means that we're multiplying our unknown, x, by 5. That is equal to 5x. 9 less than that would be 5x - 9. Since we know that it's equal to -30, we can solve.

5x - 9 = -30

Get all terms with x on one side and the constants on the other

5x - 9 +9 = -30 + 9

Simplify

5x = -21

Now, we can divide both sides by 5 to get our answer of x = -\frac{21}{5}

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
Nezavi [6.7K]

Answer:

The average spent at his store is of $37.60.

The average spent at his competitor's store is of $48.53.

Step-by-step explanation:

Average of a data set:

The mean of a data set is the sum of all values divided by the number of values.

His store:

15 orders.

Prices of: 41, 38, 19, 30, 21, 53, 34, 34, 37, 29, 50, 43, 57, 28, 50

The average is:

M = \frac{41 + 38 + 19 + 30 + 21 + 53 + 34 + 34 + 37 + 29 + 50 + 43 + 57 + 28 + 50}{15} = 37.6

The average spent at his store is of $37.60.

Store of the competitor:

15 orders

Prices of: 86, 15, 75, 40, 51, 60, 27, 45, 112, 7, 65, 31, 18, 27, 69

The average is:

M = \frac{86 + 15 + 75 + 40 + 51 + 60 + 27 + 45 + 112 + 7 + 65 + 31 + 18 + 27 + 69}{15} = 48.53

The average spent at his competitor's store is of $48.53.
