Which of the sets of ordered pairs represents a
function? **easy** BRAINLIEST
A= {(2,-2). (5, -5), (-2, 2), (-5, 5)}
B = {(4, 2), (4, -2). (9, 3), (9, -3)}

O Only A
O Only B
O Both A and B
O Neither A nor B​

Answers

A function means that “for only x, there is one and only one y”. If you look at these sets, you can see that the statement is true for A, but not for B. In B, you can see that an x-value of 4 has two y-values (2 and -2) and a value of 9 also has two y-values. Therefore, only A is a function.
A is a set with ordered pairs. This is because for a function to work there can not be a multiple of an input number. So only A would work since there is no input number that is repeated. Hope this helps and if you could please consider marking me the brainliest, thank you!

Answer:

[tex]Q=(9,11)[/tex]

Step-by-step explanation:

Solving (4a)

[tex]P (x_1,y_1) = (1,1)[/tex]

[tex]M (x,y) = (5,6)[/tex]

Required

Determine [tex]Q(x_2,y_2)[/tex]

To do this, we make use of the mid-point formula:

[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Substitute values for x, y, x1 and y1

[tex](5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2})[/tex]

Multiply through by 2

[tex]2 * (5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2}) * 2[/tex]

[tex](10,12) = (1+x_2,1+y_2)[/tex]

By comparison:

[tex]10 = 1 + x_2[/tex]

[tex]x_2 = 10 - 1[/tex]

[tex]x_2 = 9[/tex]

[tex]12 = 1 + y_2[/tex]

[tex]y_2 = 12 - 1[/tex]

[tex]y_2 = 11[/tex]

Hence, the coordinates of Q is (9,11)

Write a proportion for this situation, and then solve.

A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the perimeter of the pizza slice. (no answer)​

Answers

Answer:

The perimeter of the pizza slice is 20.1 cm

Step-by-step explanation:

Perimeter of a Sector of a Circle

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

[tex]\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}[/tex]

The perimeter is:

[tex]P = 7*\frac{5\pi}{18} + 2*7[/tex]

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm

Solve for x: 3500=700*2^8x Check all that apply.

Answers

3500=700 \times 2 ^ { 8x }

\frac{3500}{700}=2^{8x}

5=2^{8x}

2^{8x}=5

\log(2^{8x})=\log(5)

8x\log(2)=\log(5)

8x=\frac{\log(5)}{\log(2)}

8x=\log_{2}\left(5\right)

x=\frac{\log_{2}\left(5\right)}{8}

[tex]\text{The \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)} \text{\ for the \textbf{equation},}\ 3500=700\times 2^{8x}.[/tex]

So, option c) and d) are correct.

Logs with base a, they are called Common Logs and Logs with base e are called Natural Logs.

[tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]

Given equation:

[tex]3500=700\times 2^{8x}\\[/tex]

In order to solve it for x first take logarithm both sides of the equation as follows:

We can take log natural as well as common log

1. taking common log:

[tex]log(3500)=log(700\times 2^{8x})\\log(3500)=log(700)+log( 2^{8x})\\log(3500)-log(700)=8x\ log( 2)\\\\log\dfrac{3500}{700}=8x\ log( 2)\\\\log5=8x\ log2[/tex]

Evaluating x as follows:

[tex]x=\dfrac{\log(5)}{8\log(2)}[/tex]

2. Similarly on taking natural log:

[tex]x=\dfrac{\ln(5)}{8\ln(2)}[/tex]

[tex]\text{Thus, the \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)}[/tex][tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]

How many solutions does 2x-4=4-2x have?

Answers

Answer:

8/4 or 2

Step-by-step explanation:

2 solutions

The equation 2x - 4 = 4 - 2x has a single solution, x = 2.

The equation 2x - 4 = 4 - 2x can be simplified and analyzed to determine the number of solutions.

First, let's simplify the equation by combining like terms:

4x - 4 = 4

Next, we can add 4 to both sides of the equation to isolate the variable:

4x - 4 + 4 = 4 + 4

This simplifies to:

4x = 8

Now, we divide both sides of the equation by 4 to solve for x:

(4x) / 4 = 8 / 4

This yields:

x = 2

Therefore, the equation 2x - 4 = 4 - 2x has a single solution, x = 2.

This means that when we substitute x = 2 into the original equation, both sides will be equal. Thus, the equation has a unique solution, indicating that the two sides of the equation represent the same line or point of intersection.

In summary, the equation has one solution, which is x = 2.

If \displaystyle xx is the price of a child ticket in dollars and \displaystyle yy is the price of an adult ticket in dollars, write a system of equations that models this situation and then solve it to find out how much each type of ticket costs.

Answers

Answer:

Children ticket cost $30 and adult ticket costs $40.

Step-by-step explanation:

Given that:

x = price of a child ticket

y = price of an adult ticket

According to given statement;

3x+2y=170     Eqn 1

4x+6y=360    Eqn 2

Multiplying Eqn 1 by 3

3(3x+2y=170)

9x+6y=510      Eqn 3

Subtracting Eqn 2 from Eqn 3

(9x+6y)-(4x+6y)=510-360

9x+6y-4x-6y=150

5x=150

Dividing both sides by 5

[tex]\frac{5x}{5}=\frac{150}{5}\\x=30[/tex]

Putting x=30 in Eqn 1

3(30)+2y=170

90+2y=170

2y = 170-90

2y = 80

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{80}{2}\\y=40[/tex]

Hence,

Children ticket cost $30 and adult ticket costs $40.

35 Degrees. This is because the a straight line is 180 degrees. Knowing this, 180-100= 80. 80+65= 145. 180-145=35 which is the missing angle.

Answer:

The Missing Angle is 35°

Step-by-step explanation:

Given :-

DFE = 65° , RDE = 100°

To Find :-

DEF (?)

Solution :-

We know that angle made by a straight line is 180°

So ,

∠ RDE + ∠ FDE = 180°

100° + ∠ FDE = 180°

FDE = 80°

The sum of all angles in a triangle is 180°

Therefore ,

∠ DEF + ∠ DFE + ∠FDE = 180°

∠ DEF + 65° + 80° = 180°

∠ DEF = 35°
