Here are your equations:
r = diameter/2
C = 2*pi*r

Now all you have to do is plug in the 4.75 for the diameter, and you have your answer!
If you don't have a calculator with "pi" on it, use 3.14159.

The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7

Is −4[3(x−7)] and 6(14−2x) equiviant

Paraphin [41]

Answer:

Yes.

Step-by-step explanation:

Set the equations equal to each other to determine their equality.

-4[3(x - 7)] = 6(14 - 2x)

Distribute the 3 and the 6 into their respective parenthesis.

-4[3x - 21] = 84 - 12x

Distribute the -4 into the brackets.

-12x + 84

Rearrange the equations.

84 - 12x = 84 - 12x

Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.

Answer:

The domain restriction for (f/g)(x) is x=7

Step-by-step explanation:

we have

$f(x)=6x+2$

$g(x)=x-7$

$(f/g)(x)=\frac{6x+2}{x-7}$

Remember that

the denominator can not be equal to zero

Find the domain restriction

x-7=0

x=7

therefore

The domain is all real numbers except the number 7

(-∞,7)∪(7,∞)

What is the slope of the line represented by the equation –5x 2y= 10 ?

Sladkaya [172]

In the equation y=mx+b, the variable m represents the slope of the line. Therefore, the equation -5x+2y=10 can be rearranged into 2y=5x+10. Isolate the y to get y=2.5x+5. The slope of the line is 2.5
