Answer: the third option
Step-by-step explanation:
2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
3/2(2/3x)=8/3(3/2)
6/6x=24/6
x=4
2. A exponential decay because it is decreasing by 4. 64÷4= 16 16÷4= 4 4÷4=1
3. Neither because it is arithmetic
Answer: False, A map is a function that takes a point as an input and produces a point as an output
Step-by-step explanation:
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!
