Four times a number was 22 greater than twice the same number. What was the number?

Setler [38]

Answer: 11

Step-by-step explanation:

Set up an equation

Based on the question, we can determine that 4x = 22 + 2x where x in is the number

"Four times a number" -> 4x

"was" -> =

"22 greater than" -> 22 +

"twice the same number" -> 2x

Put the underlined parts together to get 4x = 22 + 2x

Solve equation

Rearrange/collect like terms to solve for x by subtracting 2x from both sides

4x = 22 + 2x

2x = 22

Solve for x by dividing each side by 2

2x = 22

x = 11

Final Answer

x = 11

Which function is represented by the graph below?

Ymorist [56]

Answer:

$f(x)=2^x$

Step-by-step explanation:

Exponential function:

$f(x)=a(b^x)+c$

Step 1. Find a, y-intercept

Step 2. Find b, slope

Step 3. Find c, horizontal asymptote

a = 1

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 1)/(1 - 0) = 2/1

b = 2

c = 0

$f(x)=1(2^x)+0\\f(x)=2^x$

If a cylindrical barrel measures 22 inches in

Alla [95]

You first need to calculate the circumference as that will give you the distance in one revolution.

Then you multiply the answer you get by 8

Circumference = pi*diameter = 22pi 8 revolutions = 8*22*pi = 176pi
