No, it is not a function, since 6 is repeating itself and the x should never repeat if it’s a function.

Solve the equation 6x + 12 = 4x - 18

kenny6666 [7]

Answer:

X = -15

Step-by-step explanation:

6X +12 = 4X -18

Subtract 4X from both sides

2X +12 = -18

Subtract 12 from both sides

2X = -30

Divide both sides by 2

X = -15

So basically just have the unknown on one side and normal numbers on the other. Make sure you do the same thing on both sides.

Tony finishes baking cookies at 10:33 am he started at 7:18 am now long was he baking cookies?

Ber [7]

To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:

10:33
-
7:18

Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies.

How to find the slope from a table of data

sammy [17]

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is $\frac{dy}{dx}$ or:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

$\frac{2 - 1}{2 - 1}$

$\frac{1}{1} = 1$

Therefore the slope is 1.
