Answer:4
Step-by-step explanation:
Answer:
ok here are the rules for negitive numbers
positive+positive=positive
postive+negitive=negitive(or negitive+postive=negitive)
negitive+negitive=negitive
i thing you are slightly confused so i'll do some examples of problems with negitive number
5+-5=5-5=0
-5+5=5-5=0
Hope This Helps!!!
Let us consider the function given. It is
. The coefficient of x (here 1/2) gives the frequency of the curve. What this means is that we see 1/2 a cycle between x=0 and x=
. Put another way, to see a full cycle we would need
. The period of the function given is
.
Let us think about a cycle of cosine. It starts (x=0) and ends (
) its cycle at its highest value (here f(x)=1). It is at it's lowest (here f(x)=-1) in the middle (
) it is between the highest and the lowest that it crosses the x-axis.
That is, it has an x-intercept between 0 and
That is, at
The next one comes between
and
. That is, at
The attached shows the function and it's x-intercepts. You can see that they occur at:
. This is the arithmetic sequence that contains the x-intercepts of the function.
As you can see the nth zero will occur at
12:15 = 8:X
X=cardboard box shadow
you find x by treating this equation like a proportion.
so 15(8)÷12=x
X=10
Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
