Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Answer:

[tex]2n + 4 = 3n - 6[/tex]

Step-by-step explanation:

In order to translate from words into equarion, we just have to know what means what.

Twice a number can be represented as [tex]2n[/tex], adding four to that is [tex]2n + 4[/tex].

3 times a number is [tex]3n[/tex], and 6 less than that is [tex]3n-6[/tex].

So these are equal to each other, we get [tex]2n + 4 = 3n - 6[/tex].

Hope this helped!

Answer:

$1.02 million

Step-by-step explanation:

Given

[tex]Amount = \$1.22\ million[/tex]

[tex]\%\ increase = 20\%[/tex]

Required

Determine the amount in 2007

Let the amount in 2007 be represented with x.

The relationship between these parameters is:

[tex]1.22\ million = x + 20\%\ of\ x[/tex]

[tex]1220000 = x + 20\% * x[/tex]

[tex]1220000 = x + 0.20* x[/tex]

[tex]1220000 = x + 0.20x[/tex]

[tex]1220000 = 1.20x[/tex]

Divide both sides by 1.20

[tex]\frac{1220000}{1.20} = x[/tex]

[tex]1016666.67 = x[/tex]

[tex]x = 1016666.67[/tex]

Hence, they paid $1.02 million in 2007

Answer:

x=13

Step-by-step explanation:

[tex]g(x)=-4\\[/tex]

Therefore, substituting the value in the equation

[tex]g(x)=\sqrt{x+3} -8\\=>-4=\sqrt{x+3}-8\\ =>-4+8=\sqrt{x+3} \\=>4=\sqrt{x+3}\\[/tex]

Squaring both sides,

[tex]=>4^{2}=\sqrt{(x+3)} ^{2}\\=>16=x+3 \\=> x=16-3\\\\=>x=13[/tex]

Answer:

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be : 4048.17

Step-by-step explanation:

3000 deposit amount, 2.9 compound monthly interest .  save 80 dollars  per month at home .

A=p(1+r)^t

A=3000(1+0.029/12)^12t

A=3000(1.002417)^12t dollars

for the amount saved at home=80*12t=960t dollars

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be :

C(t)=3000(1.002417)^12t+960t

     =3088.17+960= 4048.17 dollars

Answer:

The product is usually smaller than the two numbers multiplied

Step-by-step explanation:

When we multiply two decimals less than one, it is a certainty that the result of the multiplication would be less than the two decimals that were multiplied. An example is the multiplication of the decimals below;

0.958 * 0.325

which equals 0.31135

We can see from the example above that the result of the multiplication of the two decimals that are less than one, results in a product that is less than the factors that were multiplied.

Answer:

-15 = 7n + 8n

-15 = 15n

n = -1

plz brainlist me I need it

n = - 1

- 15 = 7n + 8n

15n = - 15

n = - 15 : 15

n = - 1

Answer:

P(x)=3x-150

Step-by-step explanation:

It is given that,

Daily revenue, R(x) = 5x, x is the number of customers that visit the gym each day

The daily cost pf the gym, C(x) = 2x+150

We need to find the profit function. It is given by :

P(x) = R(x) - C(x)

P(x) = 5x-(2x+150)

P(x) = 5x-2x-150

P(x)=3x-150

So, the correct option is (c) "P(x)=3x-150".

Answer:

Step-by-step explanation:The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .

Given two sides

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

Greetings from Brasil...

Solving the inverses of these functions and applying the composite we obtain:

(G⁻¹ о F⁻¹) = X

Note that (F⁻¹ о G⁻¹) also results in X (see second annex)

Answer:

This is a simple multiplication problem.

If 2 people, Amanda and her best friend divide evenly and each get $24.28, this means that the total is $24.28 x 2

$24.28 x 2

$48.56

I'm sorry if I misunderstood.

Good luck mate! :)

Answer:

Umm may be 105

Step-by-step explanation:

here a=5 b=7

3ab means 3×a×b

so,

3×5×7

=105

Answer:

[tex]\Huge \boxed{\mathrm{105}}[/tex]

Step-by-step explanation:

[tex]3ab[/tex]

The value of [tex]a[/tex] is given 5.

The value of [tex]b[/tex] is given 7.

[tex]\Rightarrow 3(5)(7)[/tex]

Evaluate the expression.

Answer:

if y=4.then 6(r+4).

which is 6r+24.

and if it is equal to zero which is like this then it will be 6r+24=0.

which will be 6r=-24.

r= -24/6.

r= -4.

Answer:

10

Step-by-step explanation:

| 2+3(-4)|

Using PEMDAS, multiply first

| 2+-12|

Then add

| -10|

Then take the absolute value

10

Answer:

[See Below]

Step-by-step explanation:

Rewrite:

* |2 + 3 x -4|

Solve:

* 2 + 3 = 5

* 5 x -4 = -20

Now solve using absolute value:

* -20 = 20

(With absolute value it's just a short way of saying no negatives or fractions. It'd be the whole number of the number. Another example of this would be 8/1; the absolute value would be 8.)

Answer:

Strips should be 1.5 ft wide.

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

[tex]7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5[/tex]

[tex]6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2[/tex]

The common factors are highlighted above as underlined.

Therefore, the answer is 3 [tex]\times[/tex] 0.5 = 1.5 ft

Strips should be 1.5 ft wide.

the answer would be -3 because you would do 9-12 which would be -3

Answer:

Please see the attached images for full solution.

For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.

Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.
