Which number line represents the solutions to |-2x| = 4?

Answer:

I think its B I am not houndered percent sure

Explanation:

Because if you put parallelograms on both sides it will make a shape

Answer:

( x-3) (x-8)

Step-by-step explanation:

the zeros of a quadratic are the roots of the equation so you could factor as (x-root 1)(x-root2) = ( x-3) (x-8)

(x-3) and (x-8) are the factors

Answer:

The best bet would be x=40

Answer:

-4

Step-by-step explanation:

-4 would be larger than -5 because negative numbers get smaller the farther they are from zero.

Answer:

The correct option is 345.4 :)

Step-by-step explanation:

1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.

2. The area of a circle is πr² where r is the radius of the circle. It is true.

3. The area of a circle is equal to pi divided by the square of the radius. It is false.

4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.

5. If r = 2.1 m

Area of circle, A =  πr²

= 3.14 (2.1)²

= 13.85 m²

Answer:

a) This probability as empirical Probability.

b) This probability is not accurate because this experiment must be repeated a large number of times for empirical probabilities should be accurate.

Step-by-step explanation:

On 6 occasions, of which three times the train was late. that means 3 times the train is on time.

Empirical probability = Number of outcomes satisfying event / No.of trails

                                = 3/6 = 0.5.

a) This probability as empirical Probability.

b) This probability is not accurate because this experiment should be repeated a large number of times for empirical probabilities should be accurate.

Answer:

the answer would be positive 3 over 2

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

Explanation:

If we plug the coordinates of point A into the inequality, then we get

x+y > -2

10 + (-1) > -2

9 > -2

That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers

Choices B and D are also answers for similar reasons.

Something like choice C is not a solution because

x+y > -2

-1+(-9) > -2

-10 > -2

which is false

You should find that choice E is false as well.

---------------------

If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.

The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.

Step-by-step explanation:

The possible values of ∠H, to the nearest 10th of a degree 77.4 degrees

To get the possible values of m<H, we will use the sine rule as shown:

g/sin∠G = h/∠H

Given the following parameters:

Substitute the given parameters into the formula to have:

9.3/sin109 = 9.6/sin∠H

9.3sin∠H = 9.6sin109

sin∠H = 0.98

∠H =

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (x₁, y₁) and let (-6, 4) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]

Simplify:

[tex]d=\sqrt{(-8)^2+(7)^2}[/tex]

Evaluate:

[tex]d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}[/tex]

Our answer is C.

Answer:

slope = -5 equation= y=-5x+100

Step-by-step explanation:

pick the x and y intercepts as your points to find the gradient that is

(20,0) and (0,100)

slope =∆y/∆x

=100/-20

= -5

take point(20,0) and (x,y) to find equation using the slope

equation becomes y= -5x+100

Answer:

21.77

Step-by-step explanation:

Applying,

V = (4/3)π(R²-r²)³/²................. Equation 1

Where  V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie

From the question,

Given: R = 2, r = 1

Constant: π = 3.14

Substitute these values into equation 1

V = 4/3(3.14)(2²-1²)³/²

V = (12.56/3)(3)³/²

V = 4.19(5.196)

V = 21.77

Answer:

2 1/4

Step-by-step explanation:

We have to make the first value into an improper fraction, which makes 3 3/8 into 27/8. Now we subtract 9 from 27, giving us 18. This 18 is still over the common denominator of 8. 8 goes into 18 twice with 2 left over. So we have our mixed number as 2 2/8, which can be simplified to 2 1/4.

  D.  not enough information

Step-by-step explanation:

No relationship is shown between the sides of triangle CDE and triangle ABC. There is not enough information to make any claim regarding side lengths x or y.

Answer:

y = {0 , 12}, x = -1

point 1     (-1, 0)

point 2    (-1, 12)

Step-by-step explanation:

use the distance formula

d² = (∆x)² + (∆y)²

-----------------------------

10 units away from the point (7,6)

x-cordinate of -1

10² = (-1 - 7)² + (y - 6)²

100 = 64 + (y - 6)²

Subtract 64 from both sides

36 = (y - 6)²

Take the square root of both sides

±6 = y - 6

Add 6 to both sides

y = {0 , 12}

point 1

(-1, 0)

point 2

(-1, 12)

[tex]P(X = 0) = 0.2[/tex]

[tex]P(X = 1) = 0.2[/tex]

[tex]P(X = 2) = 0.2[/tex]

[tex]P(X = 3) = 0.2[/tex]

[tex]P(X = 4) = 0.2[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

pmf of X.

Probability of each outcome, 0, 1, 2, 3 or 4 white balls drawn.

Before the trials, you are equally as likely to get the black ball in the 1st trial(0 white balls drawn) to the 5th trial(4 white balls drawn). So this is an uniform distribution with [tex]P(X = x) = \frac{1}{5} = 0.2[/tex]

Thus, the pmf is:

[tex]P(X = 0) = 0.2[/tex]

[tex]P(X = 1) = 0.2[/tex]

[tex]P(X = 2) = 0.2[/tex]

[tex]P(X = 3) = 0.2[/tex]

[tex]P(X = 4) = 0.2[/tex]

Answer:

A1 7% = $400 & A2 8% = $16,600

Step-by-step explanation:

A1 * 7% + A2 * 8% = 1356

A1 + A2 = 17000

A1 = 17000 - A2

(17000 - A2) * 0.07 + A2 * 0.08 = 1356

1190 - 0.07 A2 + 0.08 A2 = 1356

1190 + 0.01 A2 = 1356

0.01 A2 = 166

A2 = 16600

A1 = 17000 - A2

A1 = 17000 - 16600

A1 = 400

The quotient obtained by dividing 4x²+3x+2 will be 4x + 15 hence option (A) will be correct.

An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraint.

Given that

dividend  =  4x²+3x+2

divider = x -3

⇒ (x - 3) / 4x²+3x+2

⇒ (x - 3) / 4x²+3x+2

→ First it will goes for 4x time so 4x × (x - 3) = 4x² - 12x

Quotient = 4x

so (4x²+3x+2) - (  4x² - 12x ) = 15x + 2

(x - 3) / 4x²+3x+2

→ Second time it goes for 15 so 15 × (x - 3) = 15x -45

Quotient = 15

so  (15x + 2 ) - (  15x -45 ) = 47

Hence, 47 will be the remainder and the quotient will be (4x + 15).
