Answers

Answer 1

Answer:

A. f(x) = 6.5xB. f(x) = 3x - 2

Step-by-step explanation:

Table A

This is proportional relationship

The function is:

f(x) = 6.5xTable B

The slope is:

(10 - 7)/(4 - 3) = 3

The y-intercept is:

10 - 4*3 = -2

The function is:

f(x) = 3x - 2
Answer 2

Answer:

If x = 8, what is the value of 4x + 6?
I NEED HELP! I’m on a test!!

Answers

Answer:

=38

Step-by-step explanation:

Use substitution :3

4(8)+6=38

substitute x to 8 then calculate!

There you'll get your answer.

the required value of expression 4x + 6 is 38 when x = 8.

If x = 8, what is the value of 4x + 6 to be determine.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

What are equations?

The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.

Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38

Thus, the required value of expression 4x + 6 is 38 when x = 8.

This is a picture of a coordinate grid.
Which ordered pair describes a point that is located 5 units to
the right of the origin and 2 units below the x-axis?

Answers

Answer:

(5,-2)

Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .

The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).

What is the coordinate grid?

A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

Given a statement for coordinates a point that is located 5 units to

the right of the origin and 2 units below the x-axis,

so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.

5 units to the right, which is the coordinate of x is 5

and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,

2 units below the x-axis, which is coordinate of y is -2

point is (5, -2).

Hence the coordinates of points are (5, -2).

25 points. Which problem will graph as shown?

A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14

Answers

Answer:

D

Step-by-step explanation:

We can work backwards.

First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.

Our final answer is all values less than -3. So:

[tex]x<-3[/tex]

We can multiply both sides by 3:

[tex]3x<-9[/tex]

And then subtract 5 from both sides:

[tex]3x-5<-14[/tex]

So, the answer that matches this will be D.

Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

How to calculate 46% of 50

Answers

Answer:

the answer is 23

Step-by-step explanation:

100/50=2

46/2=23

Answer:

23

Step-by-step explanation:

50/x=100/46

(50/x)*x=(100/46)*x       - we multiply both sides of the equation by x

50=2.17391304348*x       - we divide both sides of the equation by (2.17391304348) to get x

50/2.17391304348=x

23=x

x=23

now we have:

46% of 50=23

Find the measure of each angle indicated.

Answers

Answer:

90

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

x + 70 =120       {Exterior angle theorem}

        x = 120 - 70

       x = 50

y = x     {Vertically opposite angles}

y = 50

z + 50 + 40 = 180          {Angle sum property}

 z + 90  = 180

          z = 180 - 90

          z = 90

Answers

Answer:

32 people got off

Step-by-step explanation:For the 10th stop, we can get the total number of people that have gotten off

Mathematically, this is the product of the mean and the number of stops

= 10 * 6.3 = 63 people

Now, for the 11th stop, the total becomes

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)

Answers

Answer:

(3,-4)

Step-by-step explanation:

You can find the vertex where x = -b/2a

To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c

y = 2(x^2 - 6x + 9) - 4

y = 2x^2 - 12x + 18 - 4

y = 2x^2 - 12x + 14

In this equation, a = 2 and b = -12.

So let's plug that into x=-b/2a

x = -(-12)/2(2)

x = 12/4

x = 3

Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.

y = 2(x - 3)^2 - 4

y = 2(3 - 3)^2 - 4

y = -4
