The answer is A since there are x egg sandwiches that cost $3.10, y beef that cost $3.35 and z cheese sandwiches that cost $2.85, so buying one more of any of those would mean paying that amount a the number of times you buy it. So 2 of x is $3.10 x 2 = $

Answer:

Mrs. Wang is 38 years old and her daughter is 15 years old.

Step-by-step explanation:

Explanation:

Let

x

=

the daughter's age

Mrs. Wang is

23

years older, so her age is

x

+

23

In five years, the daughter will be

5

years old

In five years, Mrs. Wang will be

+

28

years old

And, in five years the sum of their ages will be 63, so...

A gardener brought 5 rabbits, after 2 months rabbits became 10, and after 4 months they became 20. If the growth continues on th

Bogdan [553]

Answer:

60

Showing-MY-Work:

4 months is 1/3 of a year. (12 months = 1 year)

Since know that they became 20, after 4 years, then we just times 20 by 3.

Because 3 times 4 = 12

20 times 3 = answer you're looking for

A coordinate plane with a line drawn passing through the points (0, 3) and (3, 2).

Margaret [11]

Answer:

None of the equations given is the equation of the function. The correct equation is: $y=-\frac{x}{3}+3\\$

Step-by-step explanation:

First we must find the slope of the line that passes through these points.

The slope between two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is given by:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

where $m$ is the slope

In this case since we have the points: $(0, 3)$ and $(3, 2).$

$x_{1}=0\\y_{1}=3\\x_{2}=3\\y_{2}=2$

and the slope will be:

$m=\frac{2-3}{3-0}=\frac{-1}{3}$

and now we have the slope we use the slope-point equation:

$y=m(x-x_{1})+y_{1}$

$y=-\frac{1}{3}(x-0)+3\\ y=-\frac{x}{3}+3\\$

Please help me Graph Y=f(x) <br><br>

Jobisdone [24]

Step-by-step explanation:

f(0) = 0 , f(2) = -4 , f(4) = -2

0 = f(2x) → f(0) = f(2x) → x = 0 (0,0)

-4 = f(2x) → f(2) = f(2x) → x = 1 (1,-4)

-2 = f(2x) → f(4) = f(2x) → x = 2 (2,-2)

shape of the graph remain without change in vertical axis , but it is compressed in the horizontal direction.
