Answer:

The first graph

Step-by-step explanation:

-2x is the key here, when you add a subtraction sign to the x-axis it goes right.

+2x would be the graph on the bottom because it is translated to the left.

So the first graph on your picture is the answer.

Answer+Step-by-step explanation:

Answer:

A)6

Step-by-step explanation:

First we can create a second traingle  show in the picture so we figure out the base is 8 and hypotenuse is 10

so we use pythagerous

10^2-8^2=36

root of 36=6

Therefore x is 6 as they are the same height do to us knowing its a rectangle as it has 90 degree angles

Answer:

Step-by-step explanation:

A vertical shift is when the graph literally moves vertically, up or down. The movement is all based on what happens to the y-value of the graph. The y-axis of a coordinate plane is the vertical axis. When a function shifts vertically, the y-value changes.

The angle made by an arc at the centre of the circle is double the angle made by the same arc at any point on the circle. The measure of the angle θ will be 45°.

According to the arc and subtended angle theorem, The angle made by an arc at the centre of the circle is double the angle made by the same arc at any point on the circle.

The angle made by an arc at the centre of the circle is double the angle made by the same arc at any point on the circle. Therefore, the measure of the angle θ will be half the measure of the ∠P.

As it can be observed the measure of the angle ∠P is 90°, therefore, the measure of the angle θ can be written as,

∠P = 2 × ∠θ

90° = 2 × ∠θ

∠θ = 45°

Hence, the measure of the angle θ will be 45°.

The -5⁻³ matches with -1/125, (-5⁻³)⁻¹ matches with -125, and (-5⁻³)⁰ matches with 1.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

5⁻³ = 1/5³ = 1/125

-5⁻³ = -1/5³ = -1/125

(-5⁻³)⁻¹ = (-1/5³)⁻¹ = (-1/125)⁻¹ = -125

Answer:

A) 30x

Step-by-step explanation:

5(x - 2x + 6x + 10)

Distribute:

5(x) + 5(-2x) + 5(6x) + 5(10)

5x - 10x + 30x + 50

Therefore, 5(x - 2x + 6x + 10) is equivalent to 5x - 10x + 30x + 50

Hope this helps!

Answer:

A) 30x

Step-by-step explanation:

Given equation:

5(x – 2x + 6x + 10) = 5x – 10x + ? + 50

Let the "?" be represented as "a". Then,

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

[Right hand side] Put all the terms inside a parenthesis (except "a").

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

⇒ 5(x – 2x + 6x + 10) = (5x – 10x + 50) + a

Isolate the "a" on one side by subtracting the terms inside the parenthesis.

⇒ 5(x – 2x + 6x + 10) - (5x – 10x + 50) = (5x – 10x + 50) + a - (5x – 10x + 50)

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

[Left hand side] Simplify the distributive property

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

[Left hand side] Open the parentheses

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

[Left hand side] Combine like terms and simplify

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

⇒ x(5 – 10 + 30 - 5 + 10) + (50 - 50) = a

⇒ x(30) = a

[Left hand side] Open the parenthesis and simplify

⇒ x(30) = a

⇒ 30x = a = ?

Therefore, the correct option is A (30x).

Answer:

Step-by-step explanation:

We want to know that probability that we draw a green marble for the first AND the second AND the third draws. The act of drawing each marble changes the probabilities of the next draw, so we say that these events (drawing green marbles) are dependent. Mathematically, this means we'll be multiplying the probabilities of each event to get the probability of the whole thing. I'll denote the first, second and third green marble drawing events as A, B, and C.

For our first drawing, we have 5 possible green marbles to pick from out of 4 + 8 + 5 = 17 total marbles, so P(A), the probability of drawing a green marble, is 5/17.

Now, A, B, and C all represent the event of drawing a green marble, but the way they depend on one another is important here. If we want B to be our second draw, it'll depend on what happens in our first draw, A. We call this kind of probability conditional, and we write it as P(B | A), the conditional probability of event B after event A's occurred.

Here, event A is "drawing a green marble." What happens during event A? Well, we draw a green marble, so we have one fewer green marble, and one fewer marble altogether. Our chance of drawing a green marble after event A, P(B | A), is 4/16 or 1/4 then, since we now have 4 green marbles and 16 total marbles.

Using that same reasoning, P(C | B), the probability of event C (drawing a green marble) after event B has occurred, is 3/15, or 1/5, since we'll have 3 green marbles out of 15 total after drawing our second during event B.

Multiplying these all together, we have

The measure of the angle B is 30 degree after applying the sin law of triangle.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle shown in the picture:

We can apply the sin law of the triangle to find the angle B

[tex]\rm \dfrac{28}{sin91} =\dfrac{14}{sinB}[/tex]

SinB = 0.499

B  = 29.99 ≈ 30 degree

Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.

Answer:  B) Rotation

Explanation:

The preimage has been rotated 180 degrees to land on the image.

Proof of this is to note that a point like (2,2) maps to (-2,-2)

The 180 degree rotation rule is [tex](x,y) \to (-x,-y)[/tex]. We flip the signs of each coordinate.

You can accomplish the same thing with two reflections: one over the x axis and the other over the y axis. However, a rotation is more direct.

The events of selecting the picture of Paris and another picture of Paris with replacement are independent events.

The probability of picking two Paris pictures is 25/144.

Independents events are events whose occurrence do not depend on each other. They are random event.

The probability of picking two Paris pictures = (number of Paris pictures / total number of pictures) x (number of Paris pictures / total number of pictures)

5/12 x 5/12 = 25 / 144

Answer:

∠S = 19°

Step-by-step explanation:

Since all angles in a triangle add up to 180°, we must first find how much is left.

180 - 142 = 38

And since we know that the two lines are congruent, we know that the two other angles will be the same. So we divide the remaining by 2

38 ÷ 2 = 19

So both other angles are 19° meaning that ∠S is 19°

Hope this was helpful!

Answer: m∠S = 19°

Step-by-step explanation:

    We know the angles of a triangle add up to 180° (and if you don't, you do now)

-> We are given one angle, 142°

-> We are given the fact this is an isosceles triangle, or one with two congruent sides

    [] This means the other two angles are congruent

-> Taking this information, we will set up an equation to solve for x

180° = 142° + 2x°

38° = 2x

19° = x

x = 19°

x = m∠S, so m∠S = 19°

          m∠S = 19°
