Answer:

y = 2x² - 10

Step-by-step explanation:

We must find a pattern in the numbers. Set out the numbers in a table (Columns 1 and 2 in the table).

<u>x</u>    <u> y</u>    <u>y/2</u>    <u>y/2 + 5 </u>

2   -2      -1           4

3    8       4           9

4  22      11          16

5  40    20         25

It looks like all y-values are multiples of 2.

Let's divide them by 2 (Column 3).

The numbers don't increase evenly. We may have a quadratic function.

If we add 5 to each quotient, we get a set of values equal to x² (Column 4).

y/2 +   5 = x²

y     + 10 = 2x²

y            = 2x² - 10

The function is y = 2x² - 10.

1. Remove the parenthesis using the next rules:

\begin{gathered} -(+)=- \\ -(-)=+ \end{gathered}

2. Start to remove the parentheses from the center to the edges:

-(-(8))=-(-8)=+8=8<h2>Then, the solution is 8</h2>

I need to step-by- step ways on how this is or isn’t a solvable equation. Please HELP
Darya [45]

Answer:

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true

hope this makes sense and hope it helps :)

Need help on 7,8,9,10,11 and 12 DUE TOMORROW
Dennis_Churaev [7]
7) (12 + 6)/(2 +4)
(18)/(6) = 3

8) (42 - 24)/6
(18)/6 = 3

9) (9 + 16) - (2 x 4)
25 - 8 = 17

10) 60 - (3 + 2) x 5
60 - 5 x 5
60 - 25 = 35

11) 18 + (9/3) 
18 + 3 = 21

12) 5 x (2 + 4 + 3)
5 x (9) = 45



hope this helps
