Answer:

x = - 5

Step-by-step explanation:

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

Triangle Q S R is shown. Angle Q S R is a right angle. Altitude s is drawn from point S to point T on side Q R to form a right a

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

A family is tracking its spending habits. Over the past year, the grocery bill has ranged from $110 to $170. Suppose you were go

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:

y ≥ x² -2x -3
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:

y ≥ x² -2x -3
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.
