Answer: The answer is the second graph, attached herewith.

Step-by-step explanation: The given greatest integer function is

$g(x)=[x+3].$

We are to select the correct graph of the above function from the given four optional graphs.

We have

$g(x)=3,~\textup{for }0\leq x$

$g(x)=4,~\textup{for }1\leq x$

$g(x)=5,~\textup{for }2\leq x$ etc.

These points are satisfied by the second graph only, so this will be the correct one.

Thus, the second graph is the correct option and its image is attached.

Cara has 25$ to buy dry pet food and treats for the animal shelter. A pound of dog food cost $2 and treats are $1 apiece. If she

alina1380 [7]

Let x be the number of treats bought
Let y be the pounds of food bought

25= 2y+x

Given that she has buys 9 pounds of dog food:

25= 2(9)+x
25=18 +x
25-18 =x
7=x

With the money she has left over, she can buy 7 treats.

A is inversely proportional to b. If a=7.2 when b=-4, what will a equal when b=6?

Tpy6a [65]

Answer:

Step-by-step explanation:

To find the value of a when b=6 we must first find the relationship between them.

The statement

a is inversely proportional to b is written as

$a \: \: \alpha \: \: \frac{k}{b}$

where k is the constant of proportionality

When a = 7.2 , b = -4

So we have

$7.2= \frac{k}{ - 4}$

k = 7.2 × - 4

k = - 28.8

So the formula for the variation is

$a = - \frac{28.8}{b}$

When

b = 6

That's

$a = - \frac{28.8}{6}$

We have the final answer as

Hope this helps you

Is 68 prime because i am doing homework and im stuck on this and it is very hard so help me please

BlackZzzverrR [31]

If 68 is a prime number, then the only factors it has are 1 and 68.
If it has any other factors besides 1 and 68, then it's NOT prime.

Right away, without any higher math, you can look at just the last digit
in 68 . The last digit is '8'. That tells you that '68' is an even number,
and THAT tells you that '2' must be one of its factors. So '68' is not a
prime number.

The factors of 68 are 1, 2, 4, 17, 34, and 68 .

68 has four more factors besides 1 and 68, so it's not a prime number.
