You wrote the equation wrong- he starts with 9 pencils so that's a constant and he sharpens 11 pencils for every minute. The equation would be 9+11x with x being the amount of minutes, which in this case is 7. So you just substitute and solve.
9+11x
9+11(7)
9+77
86
Hope this helps!
Answer:
62x^2 + 16x + 1
Step-by-step explanation:
The area of a square is Side times Side.
One of the sides is (8x + 1). So the equation is,
(8x + 1) * (8x + 1)
62x^2 + 16x + 1
When x repeats it is not a function so (0,1) or (0,8) could be removed
Answer: x=32
Step-by-step explanation: 3x+18=114
We move all terms to the left:
3x+18-(114)=0
We add all the numbers together, and all the variables
3x-96=0
We move all terms containing x to the left, all other terms to the right
3x=96
x=96/3
