Answer:

16

Step-by-step explanation:

Dividing 2 fractions is the same as multiplying the fraction in the numerator with the inverse of the fraction in the denominator.

Therefore,

The linear equation that represent the pair of points (0, -1) and (4, 11) is y = 3x - 1

An equation is an expression that shows the relationship between two or more numbers and variables.

From the table, using the point (0, -1) and (4, 11), hence:

y - (-1) = [(11 - (-1))/(4 - 0)](x - 0)

y = 3x - 1

The linear equation that represent the pair of points (0, -1) and (4, 11) is y = 3x - 1

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

(-5⁻³)⁰ = 1   [tex]\rm (a^0 = 1)[/tex]

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

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:

∠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°

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)

Answer: 25%

Step-by-step explanation:

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

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.
