Answer:
{9, 7, 5, 3, 1}
Step-by-step explanation:
All you do is plus in each domain value in for the x and you get the range every time.
-2(-2)+5
-2(-1)+5
-2(0)+5
-2(1)+5
-2(2)+5
Plug in 300 for C(x), to get:
300=

Then subtract to get: 0=

Then use the quadratic formula and plug everything in. Use a calculator to simplify.
You'll get two answers: 29.486 and -0.513.
Since you can't sell <em>"negative" </em>tacos, use the positive solution
Around 29-30 tacos.
Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,
• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:

First, let's isolate x in equation A:

Now, we will replace where's x by 11-y in equation B:

As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
Answer:
My answer would be y=2x+1

Step-by-step explanation:
The frequency distribution is a summary of the gathered data set, in which the interval of values is divided into classes.
A requirement for a frequency distribution is for the classes to be mutually exclusive and exhaustive. That is, each individual, object, or measurement in the data set must belong to <em>one and only one</em> class.
Then, we can conclude that each individual, object, or measurement must appear in at least one (in fact, only in one) category or class.
