Answer:
46 and 277
Step-by-step explanation:
Given
f(x) =
- 8x - 11 ← substitute x = 3, x = - 4 into f(x)
f(3) =
- 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
f(- 4) =
- 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277
The right amount to test would be 30.
200 is to many kids and 12 is not enough.
Hope this Helps!!
Square would be the best answer
Let x be the number.
Set up an equation:
2x - 2/3x = 20
Simplify:
1 1/3x = 20
Divide both sides by 1 1/3
X = 15
The number is 15
