\frac{2 |x - 3| }{5}  = 6 \\

5 \times  \frac{2 |x - 3| }{5}  = 5 \times 6 \\

2 |x - 3|  = 30

\frac{2 |x - 3| }{2}  =  \frac{30}{2}  \\

|x - 3|  = 15

x - 3 = 15

x - 3 + 3 = 15 + 3

x = 18

<h2>OR</h2>

x - 3 =  - 15

x - 3 + 3 =  - 15 + 3

x =  - 12

24 divide by blank plus 5 multipled by 3 plus 2 equals 20
sineoko [7]

Answer:

8

Step-by-step explanation:

The answer would be 8 because the question would be

24 ÷ x + 5 × 3 + 2=20  right?

The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you  24 ÷ x + 15 + 2 = 20.

15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.

Hope this helped!

HELP
Gekata [30.6K]

Answer:

Equation:   y = 65x

Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.

Step-by-step explanation:

Pick any two points to find slope, let's got with (3, 195) and (4, 260):

  slope m = (y₂- y₁) / (x₂ - x₁)

                = (260 - 195) / (4 - 3)

                = 65 / 1

            m = 65

Find y-intercept by using m from above and another point from your table, let's go with (5, 325):

  y = mx + b

  325 = 65(5) + b

  325 = 325 + b

  b = 0

Use m and b to form equation of line:

  y = mx + b

  y = 65x + 0

  y = 65x

Check:

  point (3, 195):   195 = 65(3)       ====>   195 = 195

  point (4, 260):   260 = 65(4)     ====>   260 = 260

  point (5, 325):   325 = 65(5)     ====>   325 = 325

  point (6, 390):   390 = 65(6)     ====>   390 = 390

Example of a point that doesn't belong on table:

  point (8, 500):    500 = 65(8)    ====>   500 ≠ 520

If y&gt;0, which of these values of x is NOT in the domain of this equation? y=x2+7x
alisha [4.7K]

Answer:

\boxed{\sf \ \ \  [-7,0] \ \ \ }

Step-by-step explanation:

Hello

y=x^2+7x=x(x+7) >0\\ x>0 \ and \ x+7 >0 \ \ or \ \ x

So values of x which is not in this domain is

-7\leq x\leq 0

which is [-7,0]

hope this helps
