−2(x−2)−4x−5=29 find the x value for the equation

Mathematics
1 answer:
Anestetic [448]3 years ago
3 0

Answer:

x = - 5

Step-by-step explanation:

- 2(x - 2) - 4x - 5 = 29 \\  \therefore \:  - 2x + 4 - 4x - 5 = 29 \\ \therefore \:   - 2x - 4x + 4 - 5 = 29 \\ \therefore \:    - 6x - 1 = 29 \\ \therefore \:    - 6x = 29 + 1 \\ \therefore \:    - 6x = 30 \\ \therefore \:   x =  \frac{30}{ - 6}  \\ \huge \red { \boxed{ \therefore \:   x =  - 5}}

Neko [114]

*The diagram is in the attachment

Answer:

q = 2√14

Step-by-step explanation:

To determine the value of q, apply the leg rule/geometric mean theorem, which is:

Hypotenuse/leg = leg/part

Hypotenuse = 10 + 4 = 14

Leg = q

Part = 4

Plug in the values into the equation:

14/q = q/4

Cross multiply

q*q = 14*4

q² = 56

q = √56

q = √(4*14)

q = 2√14

Stella [2.4K]
A). I would start at $100 through $200. since the range doesn't start until $110 there is no reason to show the numbers 0-90.

b). I would then go up by 10 on each interval. going up by 10 can easily be graphed and accurate.

A system of inequalities is shown.
Doss [256]

The system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

By critically observing the graph which models the system of inequalities shown, we can infer and logically deduce the following points:

  • Both boundary lines on the cartesian coordinate are solid. Thus, the inequalities will both have the "equal to" sign.
  • The shading occurred above the quadratic boundary line. Thus, the inequalities below the linear boundary line is given by y ≥ x² + and y ≤ x +

In conclusion, we can infer and logically deduce that the system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

The app store is offering 15 percent off any purchase for one day, only you decide to buy a game app that cost 12 dollars and 90
siniylev [52]

Answer:

$1.935

Step-by-step explanation:

As the store is offering a 15% discount, you have to calculate the 15% of the price of the game app to find the amount of the discount:

Price of the game app= 12.90

12.90*15%=1.935

According to this, the answer is that the amount of the discount if you buy the game app during the sale is $1.935 and you would have to pay: 12.90-1.935= $10.965.
