I can create and use a graph to predict values and justify my results? Help me with this please I would appreciate it

Answer:

1

Step-by-step explanation:

you do the rise over run, so count how many boxes up it is from one point to the next, then put that over how many boxes to the right it is, and simplify.

ex: 1/1 = 1,    2/2 = 1,   3/3 = 1, etc.

Step-by-step explanation:

Answer:

63

Step-by-step explanation:3(3)(7)=63

Answer: 3 x 3 x 7 = 63

Step-by-step explanation: I am not sure if this is what you are asking but when a number and a variable and next to each other without any spaces it means that you should multiply them, so, 3 x m is just 3 x 3. Expanding on this, if 3 x 3 x n is equal to 3 x 3 x 7 then you can just multiply 3, 3, and 7 for a total of 63.

Answer:

The answer is b=18/z

Step-by-step explanation:

Let's solve for b.

bz/2=9

Step 1: Divide both sides by z/2.

1/2bz/z/2=9/z/2

b=18/z

Answer:

b=18/z

Answer:

C) 77

Step-by-step explanation:

77 times 2= 154

200-154= 46

Answer 4000+1600= 5600

Step-by-step explanation:

The 10% is $400. 400 times 4 is 1600. So to find the total, its 5600. Mark brainliest if this helped you

Answer:

Slope is -5/3, the y intercept is 5

Step-by-step explanation:

If you want to find cordinates you first have to solve the equation so that it is in the form mx+b=y

solve for y

5x+3y=15

-5x -5x

3y =-5x+15

3y/3 = -5x/3+15/3

y=-5/3x+5

or -5/3x+5=y

Now you know that the slope is -5/3 and the y intercept is 5

Start for 5 on the cordinate plain and go down 5 since it is negative and go to the right 3.

after you get to the bottom right of the graph you go back to 5 and just do the exact opposite of what you did above.

so go up 5 and go to the left 3 and continue until you get to the top left of the graph.

Answer:

Step-by-step explanation:

A. (5,-4)

The vertex of the graph of the function is (5,-4).

The answer is option A.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the vertex of the function y = x² - 10x + 21,

We can use the formula:

x = -b/2a

where a is the coefficient of the x² term, b is the coefficient of the x term, and x is the x-coordinate of the vertex.

In this case,

a = 1 and b = -10, so:

x = -(-10)/(2 x 1) = 5

To find the y-coordinate of the vertex, we can substitute x = 5 into the function:

y = (5)² - 10(5) + 21 = -4

Therefore,

The vertex of the graph of the function is (5,-4).

Answer:

[tex]Part = \frac{19}{20}[/tex]

[tex]Lessons = 23[/tex]

Step-by-step explanation:

Given:

[tex]Dancing\ Lessons = 24[/tex]

[tex]April = \frac{3}{4}[/tex]

[tex]May = \frac{1}{5}[/tex]

Required:

Determine the part she took

To solve this, we simply add up the part she took in April and May.

[tex]Part = \frac{3}{4} + \frac{1}{5}[/tex]

Take LCM

[tex]Part = \frac{15 + 4}{20}[/tex]

[tex]Part = \frac{19}{20}[/tex]

Hence, she took [tex]\frac{19}{20}[/tex] of the dancing lesson.

However, to calculate the number of lesson.

We have to multiply [tex]\frac{19}{20}[/tex] by the total dancing lessons.

[tex]Lessons = \frac{19}{20} * 24[/tex]

[tex]Lessons = \frac{19* 24}{20}[/tex]

[tex]Lessons = \frac{456}{20}[/tex]

[tex]Lessons = 22.8[/tex]

[tex]Lessons = 23[/tex] ---- Approximated

Answer:

Yes Borman is correct.

Step-by-step explanation:

Borman moved the decimal point 2 spaces to the left which gave her 0.153

Then she multiplied that by $148,000 to get 15.3% of it which would give her $22,644 so therefore, she is correct.

Step-by-step explanation:

Answer:

8%

Step-by-step explanation:

Given the following data;

Experimental value = 36 inches

Theoretical value = 33 inches

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]

Substituting into the equation, we have;

[tex] Percent \; error = \frac {33 - 36}{ 36} *100[/tex]

Note: we would ignore the negative sign.

[tex] Percent \; error = \frac {3}{ 36} *100[/tex]

[tex] Percent \; error = 0.833 *100[/tex]

Percent error = 8.33 ≈ 8%
