Open the brackets
8z - 2 =3z +6
Collect like terms
8z - 3z = 6 +2
5z = 8
Divide both sides by 5
Therefore 8/5 is the answer

Answer:

z = 8/5 OR 1 3/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • 2(4z-1)=3(z+2)
  • 2(4z)+2(-1)=3(z)+3(2)
  • 8z-2=3z+6

Step 2: Subtract 3z from both sides.

  • 8z - 2 - 3z = 3z + 6 - 3x
  • 5x - 2 = 6

Step 3: Add 2 to both sides.

  • 5x - 2 + 2 = 6 + 2
  • 5x = 8

Step 4: Divide both sides by 5.

  • \frac{5x}{5} = \frac{8}{5}
  • x = \frac{8}{5} OR x = 1\frac{3}{5}

State the domain and range of the following relation<br> x^2+y^2=16
Vlada [557]

The domain and range is  [-4, 4] and [0, 4]

<h3 /><h3>What is Domain and range?</h3>

The domain of a function is the set of values that we are allowed to plug into our function.

The range of a function is the set of values that the function assumes.

x² + y² = 16

y = √16 - x²

For domain under root should not be negative quantity,

16 - x²≥0

16≥x²

So, x≤4 or x≥4

Thus, the domain is  [-4, 4]

Range:

y is maximum at x=0, y=4

y is minimum at x=4, y=0

Thus, range = [0, 4]

DochEvi [55]
120 cupcakes
Even # rows
Odd # columns

12: 1, 2,3,4,6, 12 (integers?)

I see only one arrangement with odd column & even rows
3 columns, 40 rows
That's mainly because 120 is an even number.
