Answer:

Step-by-step explanation:

2(2x-1)=6(x+2) PEDMAS

4x-2=6x+12 subtract 4x from both sides

-2=2x+12 subtract 12

-14=2x divide by 2

Answer:

x = -7

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

2(2x - 1) = 6(x + 2)

Step 2: Solve for x

Distribute: 4x - 2 = 6x + 12
Subtract 4x on both sides: -2 = 2x + 12
Subtract 12 on both sides: -14 = 2x
Divide 2 on both sides: -7 = x
Rewrite: x = -7

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 2(2(-7) - 1) = 6(-7 + 2)
Multiply: 2(-14 - 1) = 6(-7 + 2)
Subtract/Add: 2(-15) = 6(-5)
Multiply: -30 = -30

Here we see that -30 does indeed equal -30.

∴ x = -7 is a solution of the equation.

Leticia Cox is a biochemist. She is testing two different types of drugs that induce cell growth. She has selected two cultures

Anna71 [15]

1. Culture A.

Since the number of cells increases by 200 each day and every day thereafter, then after seven days the number of cells will increase by

$200\cdot 7=1,400.$

2. Culture B.

The initial number of cells was 1,000. Since the number of cells increases 8% each day and every day thereafter, then after seven days the number of cells will be

$1,000\cdot (1.08)^7\approx 1,713.$

The number of cells that have grown by the end of the seventh day is

1,713-1,000=713.

Answer: option A -- Culture A: 1400 cells Culture B: 713 cells

I just need help with the table

navik [9.2K]

-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.

-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.

-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.

-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.

-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.

So, the table/coordinates are:

(-2, 5)
(0, 2)
(2, -1)
(4, -4)

I hope this makes the process clear.
