Step-by-step explanation:

its 13

Answer:

X = -1

Step-by-step explanation:

Subtract 12 from both sides

Subtract 12 from 9 to get -3

Divide both sides by 3

Divide -3 by 3 to get -1

The solution to [tex]\sqrt{3x + 12} = 9[/tex] is x = 23 and it is not an extraneous solution

The equation is given as:

[tex]\sqrt{3x + 12} = 9[/tex]

Take the square of both sides

3x + 12 = 81

Subtract 12 from both sides

3x = 69

Divide through by 3

x = 23

Substitute x = 23 in [tex]\sqrt{3x + 12} = 9[/tex]

[tex]\sqrt{3 * 23 + 12} = 9[/tex]

Evaluate the sum and product

[tex]\sqrt{81} = 9[/tex]

The above equation is true

Hence, the solution to [tex]\sqrt{3x + 12} = 9[/tex] is x = 23 and it is not an extraneous solution

Step-by-step explanation:

The slope for the given equation is 4.

Answer:

4

Step-by-step explanation:

Since the equation is written in y=mx+b form, we know that M is the value of the slope.

Since y=4x+5 is in slope intercept form, 5 would be (0,5) for y-Intercept

Answer:

○ [tex]\displaystyle y = 2x + 2[/tex]

Step-by-step explanation:

Starting from the y-intercept of [tex]\displaystyle [0, 2],[/tex]travel south two units, then west one unit to the endpoint AND x-intercept of [tex]\displaystyle [-1, 0].[/tex]Doing so will give you the rate of change of 2:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-2 ± 0}{0 - 1} = m \hookrightarrow \frac{-2}{-1} = m \\ \\ 2 = m[/tex]

With all the above information, you arrive at the equation of the line.

Answer:

7.71

Step-by-step explanation:

First off, the diameter is 3 and we know that the radius is always half of that (1.5). Since this is a semi-circle, we aren't going to multiply by 2 but instead we are going to add the diameter afterwards. So, we are going to do 1.5x3.14 which equals to 4.71. This is the part where you add the diameter which is 3. So, after you add it, you should then get 7.71!

Answer:

  0.2776

Step-by-step explanation:

A suitable calculator can tell you the area with only the "work" of entering the numbers:

  normalcdf(0.59,10) = 0.2775953248

(From a TI-83)

The area of the shaded region is about 0.2776.

__

Additional comment

The area beyond 7 standard deviations from the mean is on the order of 1.3×10^-12, so "infinity" as a limit can be effectively replaced by any number more than 7 standard deviations from the mean. We have used 10 as a stand-in for "infinity", but 7 would do nicely in this context (above), where only 10 digits are displayed.

Answer:B

Step-by-step explanation:

Since both equations are equal to y, we can set -2x-1=(1/2)x+4.

[tex]-4x-2=x+8\\-5x-2=8\\-5x=10\\x=-2\\y=-2(-2)-1=3[/tex]

This is point  B

Answer:

first you need to find the number-x

42% is equal to 0,42

( 100% .... 1

42% ..... y )

so 0,42 * x = 64,26 x = 64,26 / 0.42 = 153

so x = 153 is your number

then you have to calculate all % the same way:

10,5% equals to 0,105 ... 0,105 * 153 = 16,065

21% equals to 0,21 ... 0,21 * 153 = 32,13

63% ..96,39

84% ..128,52

Step-by-step explanation:

3x = 36

x = 36/3 = 12

Answer:

24

Step-by-step explanation:

Here we have some problems about circles, the solutions are:

We know that for a circle of diameter D, the area is given by:

A = pi*(D/2)^2

where pi = 3.14

In the image we can see that the diameter of the circle is 25 yd, replacing that in the area equation we get:

A = 3.14*(25yd/2)^2 = 490.6 yd^2

For the second image, each line creates two 180° angles. So, if we look at the tilted line, we can see that it is divided in two angles, one of 37° and the other that depends of x, so we can write:

180° = 37° + (9x + 8)°

180° - 37° - 8°  = (9x)°

135°/9° = x = 15

So the value of x is 15.

For the last image:

Notice that we have a 90° angle denoted, then the other 3 sections must add up to 270°.

270° = 54° + (2x + 21)° + (5x + 6)°

Now we solve this for x:

270 - 54 - 21 - 6 = 2x + 5x

189 = 7x

189/7 = x = 27

x is equal to 27

Step-by-step explanation:

Let the width be x

Perimeter = 2(length+width)

7 = x

The width is 7 and the length is 7 x 6 = 42

Area = length × width

Answer:

35 m²

Step-by-step explanation:

Given:

⇒ length of hedge = (1.2 ÷ 2) x 11 = 6.6 m

Given:

⇒ length of pond = 2 x 4 = 8m

Given:

⇒ width of pond = 28 ÷ 8 = 3.5 m

⇒ perimeter of pond = 2 x 8 + 2 x 3.5 = 23 m

Given:

⇒ length of flowerbed = 8 + 2 = 10 m

Given:

⇒ width of flowerbed = [23 - (2 x 10) ] ÷ 2 = 1.5 m

Area of grass = (length of gate x width of pond) + (length of flowerbed x [length of hedge + length of compost heap - width of flowerbed - width of pond])

= (2 x 3.5) + (10 x [6.6 + 1.2 - 1.5 - 3.5])

= 7 + (10 x 2.8)

= 35 m²
