What is the inverse of the function f(x) = x +3?

Answer:

6x²+4x

Step-by-step explanation:

The given expressions are 3x²- 4x-4 and 3x²+8x+4.

We need to add these two expressions.

3x²- 4x-4 + 3x²+8x+4 = 3x² + 3x² -4x+8x-4+4

= 6x²+4x

On adding the given expressions, we get the value as 6x²+4x. Hence, the sum of the given expressions is equal to 6x²+4x

Answer:

[tex]P(R\ or\ odd\ Numbered)=5/7[/tex]

Step-by-step explanation:

From the question we are told that:

Number of Red Marble [tex]n_r=6[/tex]

Number of Blue Marble [tex]n_b=8[/tex]

Sample size [tex]n=n_r+n_b[/tex]

[tex]n=6+8[/tex]

[tex]n=14[/tex]

And

No of red or Odd numbered [tex]x= 6+4 = 10[/tex]

Generally the equation for  probability the marble is red or odd numbered. is mathematically given by

[tex]P(R or odd Numbered)=x/n[/tex]

[tex]P(R or odd Numbered)=10/14[/tex]

[tex]P(R\ or\ odd\ Numbered)=5/7[/tex]

Answer:

9x + 8

Step-by-step explanation:

2(3x + 1) + 5x + 9 - 2x - 3

⇒ 6x + 2 + 5x + 9 - 2x - 3

⇒ 9x + 8

Algebra

2(3x+1)=6x+2

Then combine like terms.

6x+2+5x+9-2x-3

9x+8

Answer:

  20 = 2 + (7 -4) × 6

Step-by-step explanation:

The Order of Operations requires the parentheses be evaluated first, then the multiplication performed. Finally, the addition is performed.

If each of the blanks is filled with a single digit, the result of the multiplication must be a composite number greater than 10. Those are 12, 14, 15, 16, 18, 20. For the expression shown above, we have chosen to make the product be 18. That means the first blank is filled with 2 and the remaining blanks must evaluate to one of the products 2×9 or 3×6.

We have chosen 6 for the last blank, so the two blanks in parentheses must have a difference of 3. The digits 2 and 6 cannot be used, leaving possible choices as (3-0), (4-1), (7-4), (8-5).

Our final expression is chosen to be ...

  20 = 2 +(7 -4)×6

Answer:

c. A number relatively close to 100.

Step-by-step explanation:

Given

[tex]Range: 0 \to 1[/tex]

[tex]N =1000[/tex] --- i.e. the cells

Required

Number of cells that contains less than or equal 0.2

Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution

So, to calculate the number (n) of these cells, we do the following computation

[tex]n = 20\% * N[/tex]

[tex]n = 20\% * 1000[/tex]

[tex]n = 200[/tex]

200 is closer to 100 than 500. Hence, (c) is correct

Step-by-step explanation:

According To Question

(Diagram, Please Find In Attachment)

Question 38 . Cos ∅ = 12/13   ∅ in Quadrant-4(Where only Cos & Sec are Positive all other Functions Are Negative in this Quadrant)

Now ∅ Represent a Right Angle Triangle with Base=12 Perpendicular=5 & Hypothenese=13

Sin∅ = -5/13 , Cosec∅=-13/5 , Tan∅=-5/12 , Cot∅=-12/5 & Sec∅=13/12

Question 39 . SinX=-3/4   X Lies in Quadrant-3(Where only Tan & Cot are Positive all other Functions Are Negative in this Quadrant)

Find By Using Basic Formulas

[tex]SinX^{2}+CosX^{2}=1[/tex] ↔ Put Value of Sin∅=-3/4

We get CosX= ±[tex]\frac{\sqrt{5} }{4}[/tex] (but X Lies in Quadrant-3 Where Cosine Is Negative , So Neglect CosX= +[tex]\frac{\sqrt{5} }{4}[/tex])

So CosX= -[tex]\frac{\sqrt{5} }{4}[/tex] ...... now you get the point . All Questions Will Solve like This .

Answer:

w < 3.3

C) w < 3.3

D) w < 3.3

Answer:   [tex]w \le 3.3[/tex]

=====================================================

Explanation:

w is the weight and it may be no more than 3.3 pounds. This is the same as saying that 3.3 pounds is the highest it can go. Think of it as the ceiling.

w = 3.3 is possible or anything smaller than it is possible.

So w is 3.3 or smaller meaning we write the inequality [tex]w \le 3.3[/tex]

The answer is not w < 3.3 because that would exclude 3.3 itself.

The answer is between choices C and D. It seems like one of those inequality signs should have an underline.

Answer:mean means to average. in order to average, add all the numbers then divide by how many numbers you have.

All these ages add up to 150. because there are 7 ages, divide by 7. this is 21.4 which can be rounded to about 21

46 + 48 + 21 + 12 + 15 + 8 = 150

150 ÷ 7= 21.4285 = 21

Answer:

Real number and Irrational number

Step-by-step explanation:

Given

[tex]-\sqrt{ 20[/tex]

Required

The set it belongs to

First, solve the expression

[tex]-\sqrt{ 20} = -4.472136[/tex]

The above number is not an integer and it is not whole or natural because it has decimal points

It is not a rational number because it cannot be expressed as a simple fraction

However, the number can be categorized as either irrational or real because of the level of the decimal point in the result

Answer:

[tex]x=47^{\circ}[/tex]

Step-by-step explanation:

By definition, parallelograms have two pairs of parallel sides. Therefore, AD and BC are parallel, and the angles marked with [tex]x[/tex] and [tex]47^{\circ}[/tex] are alternate interior angles. Since alternate interior angles are equal, we have [tex]x=\boxed{47^{\circ}}[/tex]

Answer:

a) 90°

b) 90° - 35° = 55°

c) 65° - 40° = 25°

d) 90° - 65° = 25°

e) 180° - 65° = 115°

f) 180° - 35° = 145°

g) 180° - 40° = 140°

h) 65° + 35° = 100°

180° - 100° = 80°

i) 90° - 40° = 50°

j) 35° + 40° = 75°

180° - 75° = 105°

Answer:

[tex]y=2\sin(x)-1[/tex]

Step-by-step explanation:

Let's break it down:

In the sinusoidal function [tex]y=a\sin b(x-c)+d[/tex]:

To find Amplitude, divide the entire height of the function (from top to bottom) by two, or find the vertical distance between the horizontal line of symmetry and the highest/lowest point of the wave. In this case, Amplitude is 2.

To find [tex]b[/tex], use [tex]T=\frac{2\pi}{b}[/tex], where [tex]T[/tex] is the period of the function. To find the period, count the horizontal distance of the length of one complete cycle. In this case, period is [tex]2\pi[/tex] and therefore

[tex]2\pi=\frac{2\pi}{b},\\b=\frac{2\pi}{2\pi}=1[/tex].

To find Phase Shift, find the horizontal shift from the parent function [tex]y=\sin x[/tex]. In this case, there is no phase shift.

To find Vertical Shift, find the vertical shift from the parent function [tex]y=\sin x[/tex]. In this case, vertical shift is -1.

Thus, we've found:

Substituting these values into [tex]y=a\sin b(x-c)+d[/tex] , we get:

[tex]y=2\sin 1(x-0)-1=\boxed{y=2\sin(x)-1}[/tex]

Answer:

The numbers are 11 and -4

Step-by-step explanation:

Given

Let the two numbers be [tex]x[/tex] and [tex]y[/tex]

such that:

[tex]x + y = 7[/tex]

[tex]x*y = -44[/tex]

Required

Find x and y

Make y the subject in: [tex]x + y = 7[/tex]

[tex]y = 7 - x[/tex]

Substitute [tex]y = 7 - x[/tex] in [tex]x*y = -44[/tex]

[tex]x(7-x) = -44[/tex]

Open bracket

[tex]-x^2 +7x = -44[/tex]

Rewrite as:

[tex]x^2 -7x -44=0[/tex]

Expand

[tex]x^2 +4x-11x -44=0[/tex]

Factorize

[tex]x(x +4)-11(x +4)=0[/tex]

Factor out x + 4

[tex](x -11)(x +4)=0[/tex]

Solve for x

[tex]x =11; x =-4[/tex]

Recall that:

[tex]y = 7 - x[/tex]

So:

[tex]y = 7-11 = -4[/tex]

or

[tex]y = 7--4 = 11[/tex]
