Answer:

$y = - 5$

Explanation:

$3 - 2x - {x}^{2} = y$

$3 - 4 - {x}^{2} = y$

$y = 3 - 4 - 4$

$y = - 1 - 4$

$y = - 5$

Answer:

Third number is 12

Step-by-step explanation:

Let $\displaystyle \large{d}$ be common difference & $\displaystyle \large{x}$ be the third number. Set up the following equations:

$\displaystyle \large{x-2d=-2 \to (1)}\\\\\displaystyle \large{x+2d=26 \to (2)}$

Solve the simultaneous equation for x-term:

$\displaystyle \large{2x=24}\\\\\displaystyle \large{x=12}$

Let’s make sure that we get accurately answer. Substitute x = 12 in any equations which I’ll choose (1):

$\displaystyle \large{12-2d=-2}\\\\\displaystyle \large{-2d=-14}\\\\\displaystyle \large{d=7}$

Now add each terms with common difference as 7:

-2+7 = 5

5+7 = 12

12+7 = 19

19+7 = 26

So our pattern is -2, 5, 12, 19, 26. Since the question only asks for third number then the answer is 12

Select the equation that contains the point (3, 6) and in which the slope equals 1.

Lostsunrise [7]

Y - 6 = x -3
y = x - 3+ 6
y = x + 3
slope = 1

at (3, 6), x = 3
y = 3 + 3 = 6

A package of 4 mechanical pencils comes with 2 free erasers. If you get a total of 12 free erasers, how many packages of pencils

Elenna [48]

Answer:

6 packs, 9 packs

Step-by-step explanation:

The ratio of mechanical pencil to free eraser is 2:4, or 1:2.

So that means, for every free eraser you get, you bought the double amount of pencils.

12 free erasers x 2 = 24 pencils

18 free erasers x 2 = 36 pencils

And a pack of pencils contains 4.

24/4 = 6 packs

36/4 = 9 packs
