Answer:

Unless there is some context behind it, with a picture or something here you are.

Step-by-step explanation:

C=12r+2

So, we have to find out what it could be.

You can plug in anything for r, so I'll make it easy.

<u>r=1</u>

C=12*(1)+2

12*1=12+2=14

<u>C=14.</u>

What is the product of ( x + 3) ( x - 4)?
Lelechka [254]

Answer: x² - x - 12

Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.

<em>First, Outer, Inner, Last</em>.

We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.

So we have x² - 4x + 3x - 12.

Simplifying from here by combing the middle terms, we have x² - x - 12.

Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.

1. Refer to the equation 3x − 4y = 12. (a) Create a table of values for at least 4 points.
Zinaida [17]

Answer: THE TABLE OF VALUES IS ATTACHED.

Step-by-step explanation:

Given the following equation:

3x-4y = 12

You can solve for the variable "y":

3x-4y = 12\\\\-4y=-3x+12\\\\y=\frac{3}{4}x-3

Now you can give values to "x" and substitute each into the equation to find the corresponding value of "y".

For x=-1:

y=\frac{3}{4}(-1)-3=-3.75

For x=0:

y=\frac{3}{4}(0)-3=-3

For x=1:

y=\frac{3}{4}(1)-3=-2.25

For x=2:

y=\frac{3}{4}(2)-3=-1.5

With this values you can make the table shown attached.
