You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
Answer:
Domain is the values of x within the function and y is the values of y within the function. They are the defined values for x, and y respectively, where the function results in a function. For any function, the domain is the input value and the range is the output values.
Hope this helps :)
Answer:
The approximated length of arc x is 4 inches ⇒ C
Step-by-step explanation:
- The diameter of the outer circle is 28 inches
- There is a boundary with width 2 inches
That means the diameter of the inner circle is less than the diameter of the outer circle by 4 inches (2 in from each side)
- The diameter of the inner circle = 28 - 4 = 24 inches
The circumference of the inner circles formed from 20 congruent arcs of length x inches
- The circumference of the inner circle = 20 x
Now let us find x
The formula of the circumference of a circle is C = π d, where d is the diameter of the circle
∵ The diameter of the inner circle is 24 inches
∴ d = 24
∴ C = 24 π
∵ C = 20 x
- Equate 20 x by 24 π
∴ 20 x = 24 π
- Divide both sides by 20
∴ x = 3.769911184
- Round it to the nearest unit
∴ x ≅ 4
The approximated length of arc x is 4 inches
Multiply 5 by -4 the answer is -20h
