Answer:

x = 3y - 2

Step-by-step explanation:

Given the equation y = 1/3(x+2), we are to make x the subject of the formula;

y = 1/3(x+2)

Cross multiply

3y = x+2

Subtract 2 from both sides

3y - 2 = x+ 2 -2

3y - 2 = x

Swap

x = 3y - 2

This give the required equation

Answer:

2.478 million at the end of 2015

Step-by-step explanation:

Multiply the amount of population at the end of 2012 times 6%

2.1 times 0.06 = 0.126 million

So, at a constant rate, yearly, the population of Dubai increases 0.126 million

2015-2012 = 3

0.126 times 3 = 0.378 million

2.1 + 0.378 = 2.478 million

6 is the correct answer because✓36 is 6

Step-by-step explanation:

Hey there!

Given function is f(X) = 11x+7.

Let f(X) be y.

So, y = 11x+7

Interchanging"X" and "y" we get;

X = 11y+7

or, X-7 = 11y

or, y = (x-7)/11

Therefore {f}^{ - 1} (x) = \frac{x - 7}{11} [/tex]

Answer:

m = 4.58  

Step-by-step explanation:

Given equation :

2.4 ( m - 3) = 3.8

So now we open the brackets and multiply the terms.

⇒ 2.4 m - 7.2 = 3.8

⇒ 2.4 m = 3.8 + 7.2

⇒ 2.4 m = 11

⇒ m = [tex]\frac{11}{2.4}[/tex]

⇒ m = 4.58

Therefore, the correct value of the variable m by solving the equation is 4.58

Answer:

Following are the solution to the gvien question:

Step-by-step explanation:  

Let the quadratic equation is:

[tex]\to h(x) = (x + 1)^2 - 4[/tex]

vertex is:

[tex]\to h(x) = a(x -h)^2 + k[/tex]

(h) = axis of symmetry

(h,k) = vertex.

By using the given equation:

[tex]h(x) = (x - (-1))^2 - 4[/tex]

Hence,

[tex]h = -1 \\\\ k = -4[/tex]

line of symmetry [tex]x = -1[/tex]  

vertex is [tex](h,k) = (-1,-4)[/tex]

finding the x intercept:

 [tex](x + 1)^2 = 4\\\\\sqrt{(x + 1)^2} = \sqrt{4}\\\\x + 1 = \pm 2\\\\x = 2-1 \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-2 -1\\\\x = 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-3\\\\[/tex]

x -intercepts -3,1

Calculating the y-intercept when x = 0 putting into the real equation:

[tex]h(x) = (0 +1)^2 - 4 \\\\y = 1 - 4\\\\y = -3[/tex]

Answer:

Step-by-step explanation:

There are three surfaces to add up to.

A1, the top surface of the cone (r=1,h=2)

A2, The curved surface of the cylinder (r=1 , h = 13-2 = 11)

A3, The circular base of the cylinder (r=1)

The slant height of the cone, s = sqrt(1^2+2^2), s = sqrt(5)

The length (circumference of the base), l = 2 pi r = 2pi r = 2pi

The area is

A1 pi s l = pi * sqrt(5) (2 pi r) = 2(pi^2)sqrt(5)

The curved surface has an area of

A2 = 2 pi r h = 2pi (1)(11) =22pi

The base has an area of

A3 = pi r^2 = pi

Total area = A1+A2+A3 = 2sqrt(5) (pi^2) + 22pi + pi

= 2sqrt(5) pi^2 + 23pi

= 116.4  m^2 approx.

Answer:

640 Miles

Step-by-step explanation:

Answer:

y = 2x+4

Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

Answer:

(f o g)(x) = 0.8x - 15

Step-by-step explanation:

(f o g)(x) = f(g(x)) = applying first g(x), and then using that result as input value for f(x).

so, first we discount by 20% and use g(x)

g(x) = 0.8x

and then we use that in f(x)

f(0.8x) = 0.8x - 15

and that is the result.

Answer:

40

Step-by-step explanation:

Answer:

a = 0 or a = -7

Step-by-step explanation:

We are going to solve this quadratic equation by factorizing.

a² - 7a = 0

a(a - 7) = 0

a = 0 or a - 7 = 0

a = 0 or a = -7

Answer:

yeah it is -3y=-22+7/3 so y > 5

Step-by-step explanation:

Hi there!

Adjacent angles, or angles that are next to each other, add up to 180 degrees. They are supplementary.

Examples: 1 and 4, 3 and 4, 2 and 3, 1 and 1

Opposite angles, or angles that are opposite of each other, have the same measure.

Examples: 1 and 3, 2 and 4

Answer:

Step-by-step explanation:

The volume of a sphere is given as

[tex]V=\frac{4}{3}\pi r^3[/tex] and we will use 3.1415 as π:

[tex]V=\frac{4}{3}(3.1415)(4)^3[/tex] to get that

V = 268.07 cm³

Answer:

Rotary motion.

Step-by-step explanation:

Motion describes the movement of objects with respect to time.

When an object performs a circular or rotary motion, every point on the object moves around a central point in a continuous manner. Examples of objects that performs circular motion are: blades of an electric fan, rotation of the earth about its axis, the wheel of a moving bicycle etc.

From the cited examples, it would be observed that all points on the objects moves around a fixed central point.

Answer:

Answer is 1536

Step-by-step explanation:

plug in 3 for x

f(3) = 3*8^3 = 1536

Answer:

1536

Step-by-step explanation:

f(x) = 3 * 8 ^ x

x = 3

f(3) = 3 * 8 ^ 3

8^3 = 8 * 8 * 8

8^3 = 512

f(3) = 3 * 512

f(3) = 1536

Answer:

33.5 units²

Step-by-step explanation:

We can see this figure as 2 shapes: a square and a triangle. The square measures 4 x 4, and it's area is 16. That leaves the triangle, which has half the area of a quadrilateral that measures 5 x 7. The area of the quadrilateral is 35, and the triangle has an area of 17.5, which is half of that. Adding them together, we get 33.5.

Answer:

33.5 unit²

it's a mixture of triangle and square.

draw a imaginary straight line across the figure from that line which has length of 3 units and now you can see the triangle and the square. Use the formula to find area of triangle and area of square and the sum of their area will be the area of this whole figure i.e 35.5 unit²
