PLZ HELP (20 points)

Which of the sets of ordered pairs represents a function? (4 points)

A = {(−4, 5), (1, −1), (2, −2), (2, 3)}
B = {(2, 2), (3, −2), (9, 3), (9, −3)}

Group of answer choices

Only A

Only B

Both A and B

Neither A nor B

Answer:

x = 1

Step-by-step explanation:

11 = 7 + 4x

Subtract 7 from both sides

11-7 = 7-7 + 4x

4 = 4x

Divide 4 from both sides

4/4 = 4x/4

1 = x

x = 1

Check:

11 = 7 +4(1)

11 = 7+4

11 = 11

Hope this helps. Have a nice day.

Answer:

The slope is 0.5

Step-by-step explanation:

FIrst you do y2-y1/x2-x1

That makes it 6-3/2-(-4)

Simplified it's 6-3/2+4

6-3=3 and 2+4=6

So  you get 3/6=0.5

Answer

A. 2√3

B. 3√3

C. 5√2

Explanation

A. √12 = √4×3 ________ so we know that 4×3 gives us 12

= √4 ×√3_______since it is a multipling we can separate the square

= 2√3__________ we put 4 out of the square but not 3 because it is not

a perfect square

B. √27 = √9×3

= √9 × √3

= 3√3________simplified form

C. √50 = √25×2

= √25 × √2

= 5√2 ________ simplified form

Answer:

The equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]

Step-by-step explanation:

We need to find equation of the line shown in graph.

The equation of line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding y-intercept

Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.

So, when x =0, y=-1

So, y-intercept is -1

Finding Slope

Now, for finding slope, consider 2 points on graph

(0,-1) and (-2,0)

Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=0, y_1=-1, x_2=-2, y_2=0[/tex]

Putting values and finding slope:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-1)}{-2-0} \\Slope=\frac{0+1}{-2-0} \\Slope=\frac{1}{-2} \\Slope=-\frac{1}{2}[/tex]

So, slope is [tex]m=-\frac{1}{2}[/tex]

Equation of line

Now, equation of line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -1 is

[tex]y=mx+b\\y=-\frac{1}{2}x -1[/tex]

So, equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]

Answer: y = -2x + 5

Step-by-step explanation:

y = -2x + 5

slope = -2

Slope intercept form of equation of line is given by y = mx + c

where m is the slope of line

c is the y intercept i.e point where given line intersect y axis.

________________________________________________

given equation 4x + 2y = 10

we have to re-write this equation in form y = mx + c

4x + 2y = 10

subtraction 4x from LHS and RHS

4x + 2y - 4x= 10 - 4x

2y = 10- 4x

we have to eliminate 2 from y for that we

divide  LHS and RHS by 2 we

2y /2 = 10/2- 4x/2

y = 5 - 2x

rearranging it in y = mx+c form

y = -2x + 5

thus, m = -2 , c = 5

Answer:

y=-2x+5, slope= -2, y-intercept= 5 (so, first option)

Step-by-step explanation:

y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.

Answer:

505.8

Step-by-step explanation:

4215x0.12=505.8

Answer: Look at the step-by-step

Step-by-step explanation:

Part A: We can use two right triangles that represent rise over run to explain the slope of points A and B which has the same slope of points A and C. Since there will be two right triangles, they are considered similar triangles.

AB: 154 - 110= 44

44/2= 22

AC: 154 - 66 = 88

88/2=44

This means that the slope of the two sets of points is 44, and it represents the rate of change of the shark travelling away from the ocean’s surface every minute.

Part B: The initial value is 66 (m), and it represents the initial position of the shark at 0 minutes.

The equation of line is y =  where y is the distance from ocean surface and x is the time taken in minutes , where the slope is m = 44 m/min

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the number of minutes be x

Let the distance from ocean surface be y

Let the first point be P ( 0 , 66 )

where P is the initial point of the graph

Let the second point be Q ( 2 , 110 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 110 - 66 ) / ( 2 - 1 )

Slope m = 44

And , the equation of line is

y - 66 = 44 ( x - 0 )

Adding 66 on both sides , we get

y = 44x + 66

Hence , the equation of line is y = 44x + 66

Answer:

b

Step-by-step explanation:

did it on flvs

Answer:

b

Step-by-step explanation:

To find the y- intercept, let x = 0 in the equation and solve for y, that is

y = [tex]log_{10}[/tex](0 + 100) - 4

  = [tex]log_{10}[/tex] 100 - 4

  = 2 - 4

 = - 2 ← y- intercept → b

The y-intercept of the function y = log (x + 100) - 4 is -2

The y-intercept is the point where the line intersects the y-axis.

Given a function, y = log (x + 100) - 4

Solving for the y- intercept,

Let x = 0 in the equation and solve for y, that is

y = log(0 + 100) - 4

=  log100 - 4

= 2 - 4

= -2

Hence, The y-intercept of the function y = log (x + 100) - 4 is -2
