Answer:
A) h=0.5x+7
Step-by-step explanation:
given
initial height = 7 feet
growth rate = 6 in = 0.5 feet / year
let # of growing years = x
For a linear growth rate:
height after x years, h = initial height + (# of growing years) * (growth rate)
substiuting the values above into this equation
h = 7 feet + (x years) * (0.5 feet/year)
or
h = 7 + 0.5x (rearranging)
h = 0.5x + 7
We assume you mean
.. f(x) = -3*x^3 -2
.. g(x) = -3*x^-3
Then
.. f(-3) = -3*(-3)^3 -2 = -3*(-27) -2 = 81 -2 = 79
.. g(4) = -3*4^-3 = -3/64

It is helpful if you use ordinary lower-case letters for variables (except in some formulas where upper-case letters are used). The symbol "×" is used to signify multiplication, so leads to confusion when you try to use it for a variable. In plain text, the exponentiation operator is a caret (^), so x^2 means "x squared", for example. If the exponent is supposed to include an arithmetic operation, then it needs to be enclosed in parentheses, x^(3y-4), for example.
Answer:
Jorge is using pencils at a rate of 6 packs a year or a rate of 2 packs every four months.
Step-by-step explanation:
1/3 of a year is four months so that would be 2 packs every four months and if you multiply that by three you’d get 12 month, or one year, and 6 packs of pencils.
