13x-9=16
+9 +9
13x= 25
---- -----
13x 13x
x=1.92
Add nine to both sides of equation to cancel out the negative nine. Then, divide both sides by 13, which will result in the answer listed above.
Answer:
both of em
Step-by-step explanation:
Answer:
3141.59
Step-by-step explanation:
Formula: V = Pi x Radius(squared) x Height
so
Pi x 10(squared) x 10 = 3141.59
To do this, we have to solve the equation 3 times for 3 different values for f(x).
Those three numbers are -2, 2, and 4, the numbers in the range.
First solve for -2.
-2 = -2x + 6
Subtract 6 from each side:
-8 = -2x
Divide by -2 on each side:
4 = x That's one value done.
Next, solve with 2.
2 = -2x + 6
Subtract 6 from both sides.
-4 = -2x
Divide each side by -2.
2 = x Second value solved for.
Last value: 4.
4 = -2x + 6
Subtract 6 from each side.
-2 = -2x
Divide each side by -2.
1 = x. Now just put the domain together.
Domain is this:
{4, 2, 1}.
Hope this helps!
