Answer:

x = 10

Step-by-step explanation:

First you need to add like terms (x + x), which would give you 2x.

2x + 2 = 22

Then subtract 2 from both sides, causing it to cancel out one side, and 22 - 2, on the other side:

2x + 2 = 22

-2 -2

22 - 2 is 20, giving you:

2x = 20

Then divide both sides by 2:

2x/2 = 20/2

And you should get x = 10 as your answer.

While attending a major league baseball game, you think you can guess the

sweet [91]

Answer:

You would have to have guess a number larger than 31500 and smaller than 38500

Step-by-step explanation:

The answer will look something like

35000 +/- 10% (35000)

What that means is that the attendance would be smaller than 35000 or larger than 35000.

10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500

So you would have to estimate

35000 - 3500 ≤ attendance ≤35000 + 3500

31500 ≤ attendance ≤ 38500

Select the quadratic expression that represents the product below. -8x2 + 34x - 35 -8x2 - 34x + 35 -8x2 + 6x - 35 -8x2 - 6x + 35

Dvinal [7]

Use the FOIL method (First, Outside, Inside, Last)

Reorder:
(2x + 5)(-4x + 7)

2x(-4x) = -8x²
2x(7) = 14x
5(-4x) = -20x
5(7) = 35

-8x² + 14x - 20x + 35

Combine like terms

-8x² (+ 14x - 20x) + 35

-8x² - 6x + 35

-8x² - 6x + 35 is your answer

solve the below systems of equations using linear combination method. 2x + 3y =1. and y= -2x - 9. explain

rusak2 [61]

Answer:

Solving below systems of equations using linear combination method we get

x = -7

y = 5

Step-by-step explanation:

Linear combinations which is also commonly known as the addition method is used for solving the system of equations without graphs

Step 1: arrange the equation in standard form

2x + 3y = 1----------------------(1)

2x + y = -9--------------------(2)

Step 2: Set one of the coefficient to opposite sides

So lets multiply eq(2) with negative sign, so

2x + 3y = 1

-2x - y = 9

Step 3: Perform Addition

2x + 3y = 1

-2x - y = 9

-----------------------

0x +2y = 10

--------------------------

Step 4: Solve for y

2y =10

$y =\frac{10}{2}$

y = 5

Step 5: Substitute y value in equation(1)

2x + 3(5) = 1

2x + 15 =1

2x = 1-15

2x =-14

$x= \frac{-14}{2}$

x = -7
