Hey! Can someone help me solve the following inequality? please<3

Hi there! Given the equation below.

[tex] \large{r + \sqrt{x} = 9}[/tex]

First is to subtract both sides by r-term to isolate x-term.

[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

[tex] \large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }[/tex]

Alternative Solution

[tex] \large{x = {r}^{2} - 18r + 81}[/tex]

Answer

Both answers work. Any questions about this can be asked through comment.

Answer:

A = 14 units^2

Step-by-step explanation:

The figure is a triangle

A = 1/2 bh where b is the base and h is the height

A = 1/2 ( 7)*4

A = 14 units^2

Answer:

Area of triangle is 14 square units.

Step-by-step explanation:

Area of figure is given by

Area of triangle = 1/2 × b × h

Substitute the values,

Area of triangle = 1/2 × 7 × 4

multiply

Area of triangle = 1/2 × 28

Divide , to get

Area of triangle is 14 square units.

Answer:

3.50

Step-by-step explanation:

Necklace has beads and a pendant

b +p

There are 6 necklaces at a cost pf 43.80

6(b+p) =43.80

The beads for one necklace cost 3.80 so replace b with 3.80

6(3.80+p) =43.80

Divide each side by 6

6(3.80+p)/6 =43.80/6

3.80 +p = 7.30

Subtract 3.80 from each side

3.80+p-3.80 = 7.30 -3.80

p =3.50

Answer:

Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.

Answer:

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Given:

Diameter of sphere = 4.4 centimeter

Value of π = 3.14

Find:

Volume of sphere

Computation:

Radius of sphere = Diameter of sphere / 2

Radius of sphere = 4.4 / 2

Radius of sphere = 2.2 centimeter

Volume of sphere = [4/3][π][r³]

Volume of sphere = [4/3][3.14][2.2³]

Volume of sphere = [4/3][3.14][10.648]

Volume of sphere = [1.333][3.14][10.648]

Volume of sphere = 44.568

Volume of sphere = 44.57 cm³

Answer:

189.6m

Step-by-step explanation:

Area of reactangle= side₁ ×side₂

Let the other side of the rectangle be x meters.

Area of rectangle= 75.2m²

0.8x= 75.2

x= 75.2 ÷0.8

x= 94

Perimeter of rectangle

= 2(side₁ +side₂)

= 2(0.8 +94)

= 189.6 m

Step-by-step explanation:

Answer:

4y - 3x = -25

Step-by-step explanation:

The equation of a line in point-slope form is expressed as

y - y0 = m(x - x0)

(x0, y0) is the point

m is the slope

Given

(x0, y0) = (3, -4)

Also given the equation;

8x + 6y = 15

Rewrite in standard form;

6y = -8x+15

y = -8/6 x + 15/6

y = -4/3 x + 5/2

Slope m = -4/3

Since the required line is perpendicular to the given line =,

Slope = -1/(-4/3) = 3/4

Substitute into the formula;

y - (-4) = 3/4(x-3)

y + 4 = 3/4(x-3)

4(y+4) = 3(x-3)

4y + 16 = 3x - 9

4y - 3x = -9-16

4y - 3x = -25

This gives the required equation

Step-by-step explanation:

a. The sample space for this spinner would be A, B or C . Since these are the only possible outcomes in this specific spinner.

b. The spinner has a total of 6 sections but each letter has 2 sections dedicated to it. Therefore, this makes only 3 possible outcomes in which the spinner will only land on 1. This means that the probability of each letter would be 1/3

multiply 1/4 times 3 equal 3/4 or 0

Answer:

27

Step-by-step explanation:

w = 6

x = 2

5w

= 5 x 6

= 30

w / x

= 6 / 2

= 3

5w - w / x

= 30 - 3

= 27

Answer:

x = [tex]\frac{83}{36}[/tex]

Step-by-step explanation:

Given

x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )

x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = [tex]\frac{83}{36}[/tex]

Answer:

(p,r) = (1/3, 2/9)

Step-by-step explanation:

Here, we want to solve a system of equations

We can rewrite the second equation by dividing through by 2

So we have;

4p + 3r = 2

and

5p - 3r = 1

Add both equations:

9p = 3

p = 3/9

p = 1/3

Recall ;

5p - 3r = 1

3r = 5p - 1

Substitute the value or p here

3r = 5(1/3)-1

3r = 5/3 - 1

3r = 2/3

r = 2/9

So we have the solution set as;

(p,r) = (1/3 , 2/9)

Answer:

The area of the floor which is not covered by the rug is 201 square feet.

Step-by-step explanation:

length of the bedroom, L = 18 feet

width of the bed room, w = 12 feet

Area of rug = 5 x 3 = 15 square feet.

The total area of the floor,

A =L x w = 18 x 12 = 216 square feet

The are of the room which is not covered by the rug,

= area of floor - area of rug

= 216 - 15 = 201 square feet.
