Answer:
0 (undefined)
Step-by-step explanation:
distribute on the left side first:
-4(3k-6)-4k
so -12k+24-4k
combine like terms
-16k+24
now the right side
-8k+24-4k
combine like terms
-12k+24
so it'll look like this
-16k+24=-12k+24
add -12k to the left
-4k+24=24
so then subtract 24
that'll leave you with 0

Write an
explicit formula for An, the nth term of the sequence 7, -42, 252, ....
Answer:
[tex]A_n = 7(-6)^{n-1}[/tex]
Step-by-step explanation:
Key skills needed: Explicit formula, Geometric sequence
1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.
This can be done by doing -42 ÷ 7 or 252 ÷ -42
-42 ÷ 7 equals -6.
252 ÷ -42 also equals -6.
2) This means that constant is -6.
3) The general form for an explicit formula of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
--> r means the constant (or common ratio) that is being multiplied.
--> [tex]a_1[/tex] means the first term
--> [tex]a_n[/tex] means the "nth" numbered term (so [tex]a_3[/tex] is the 3rd term, [tex]a_{10}[/tex] is the 10th term and so on).
--> [tex]n-1[/tex] is just the "n" in [tex]a_n[/tex] minus 1.
4) We can use this formula to create an explicit formula for the geometric sequence in the problem.
--> [tex]r = -6[/tex] (Since we got -6 as the constant/common ratio).
--> [tex]a_1 = 7[/tex] (Since 7 is the 1st term)
This means that our formula would be --> [tex]A_n = 7(-6)^{n-1}[/tex]
Hope you understood and have a nice day!! :D
When the function f(x) = 3(5)x is changed to f(x) = 3(5)x + 22, what is the effect?
Answer:
The original function is an exponential growth function, and so is a new function, but it will be translated in to 2 units.
Step-by-step explanation:
The first function will have a horizontal asymptote at y = 0 and the second function will have a horizontal asymptote at y = 22.
A researcher compared the heights and shoe sizes 50 men selected at random. The equation shown describes a line of best fit for the data,
where x is the shoe size and y is the height, in inches.
y = 1.6x +48
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches?
Answer: 7 1/2
Step-by-step explanation: Convert 7 1/2 to a decimal then multiply it by 1.6 to get 12.00 then add 48 to get 60.

which expression is equivalent to x + x + x + 5 + 5 no mater what value substituted in for x
Answer:
3x+10
Step-by-step explanation:
Answer:
3x+10
Step-by-step explanation:
So you're going to want to count the amount of X's their are (3) and put them together (3x). Then to simplify the expression, add the 5+5 together, since they are they same type of variables. Now, you put everything together (3x+10).
