We have to find the area first
12 x 18=216 square feet
we do 216* $ 1.39= $ 300.24
Remember the order of operations and do what is in parenthses first.
Take 9 to its power first, then add 2. Once you get that, take that answer to the 83721 power.
I would give you the answer, but my calculator is saying invalid input every time I am trying to use such high exponents. Sorry :( But I hope that this helps
(x+12)^2 = 0
x + 12 = 0
x = - 12
Answer: f(-x) = x^4 -3x^2 +x^6
-f(x) = -x^4 +3x^2 - x^6
Step-by-step explanation:
at f(-x), place a negative sign inside the function of x itself:
f(-x)= (-x)^4 -3(-x)^2 +(-x)^6
because the powers are even, they cancel out.
Answer:
option A: x + 1.5y ≤ 20
option C: x + 3y ≤ 36
option D: x ≥ 0
option H: y ≥ 0
Step-by-step explanation:
It says to assume x = the number of packages of pasta and y = the number of jars of pasta sauce.
Since the number of items can not be a negative number, we have x ≥ 0 and y ≥ 0.
Condition: He has $36, and can carry up to 20 pounds of food in his backpack.
Pasta costs $1 for a 1-pound package. Pasta sauce costs $3 for a 1.5 pound jar.
If he buys 'x' packs of pasta and 'y' jars of pasta sauce, then:-
Total cost = 1x + 3y ≤ 36 dollars.
and Total weight = 1x + 1.5y ≤ 20 pounds.
Hence, we have four inequalities:-
option A: x + 1.5y ≤ 20
option C: x + 3y ≤ 36
option D: x ≥ 0
option H: y ≥ 0
