Answer:

Look below

Step-by-step explanation:

To answer the question, you have to find out how much 49 sold cookies amounts to, so multiply 49 by however much it is per cookie.

Then, subtract the daily expense, $18, by the number you got from the total amount earned from the cookies sold, and that number would show the daily profit earned by selling 49 cookies.

Hope this helps :)

At present the sum of Monica's age and daughter's age is 44 years. . After 2 years Monica's age will be three times that if her

sergeinik [125]

Answer:

Monica's age = 34 years

Her daughter's age = 10 years

Step-by-step explanation:

Let Monica's age = x

Let her daughter'sage = y

x + y = 44 -------> equ 1

After 2 years:

Monica's age = x + 2

Her daughter's age = y + 2

x + 2 = 3 * (y+2)

x + 2 = 3y + 6

x = 3y + 6 -2

x = 3y + 4

Put x value in equ 1:

3y + 4 + y = 44

4y = 44 - 4

4y = 40

y = 40/4

y = 10

x = 44 -10

x = 34

Which of the following rules could represent the function shown in the table?

kvasek [131]

ANSWER

The rule is given by the relation,

$y = 2x + 1$

EXPLANATION

We need to check and see if there is a constant difference between the y-values.

$1 - - 1 = 2 = 3 - 1$

We can see that, there is a constant difference of 2.

This means that the table represents a linear relationship.

Let the rule be of the form,
$y = mx + c$

Then the points in the table should satisfy the above rule.

So let us plug in

$(0,1)$

This implies that,

$1 =m (0) + c$

$1 = 0 + c$

$c = 1$

Our rule now becomes,

$y = mx + 1 - - (1)$

We again plug in another point say, (-1,-1) in to equation (1) to get,

$- 1 = m( - 1) + 1$

we solve for m now to obtain,

$- m=-1-1$

$- m = - 2$

$m = 2$
We now substitute back in to equation (1) to get

$y = 2x + 1$
