Set up this equation. There are 20 animals in my house. Some are cats and some are ducks. There are 72 legs in all. *

Answer:

x = -5  y = -3

Step-by-step explanation:

-3x + 2y = 9

multiply the 2nd equation by 3 to set it up for elimination

3(x - 3y)= 3(4)

3x-9y = 12

so now combine both to add

-3x + 2y = 9

3x - 9y = 12

Adding both gives you

-7y = 21

divide both by -7 and you get

y = -3

and you substitute y back into equation to get x

x - 3 (-3) = 4   gives you

x + 9 = 4

x = 4 - 9

x = -5

Answer:

8.3

Step-by-step explanation:

8.25 has to round up because of the five making it 8.3

x = 6 is not a solution to the equation x + 13 = 18.

Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.

Given the equation;  x + 13 = 18.

We plug x = 6 into the equation

x + 13 = 18

6 + 13 ≠ 18

6 + 13 is not 18

x = 6 is not a solution to the equation x + 13 = 18.

Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.

Answer:

  18 square units

Step-by-step explanation:

Referring to the figure, we see that the base AB has a slope of 1, and the altitude CD has a slope of -1. The number of unit squares crossed by these segments are, respectively 6 and 3, so the length of each is ...

  AB = 6√2

  CD =3√2

The area is half the product of the base (AB) and height (CD) so is ...

  A = 1/2bh = (1/2)(6√2)(3√2) = 18

The area of ΔABC is 18 square units.

Additional comment

It is useful to remember that the diagonal of a unit square is √2. We used that fact here. If you need to figure it using the Pythagorean theorem, you find ...

  c² = a² +b²

  c = 1² +1² = 2

  c = √2

I assume you want this explained

Answer and explanation:

If the function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations then x number of tickets is an independent variable here that will determine the total amount of funds raised y(dependent variable)

The y intercept is -320 and the slope is 5

If for example the number of tickets sold = 100 tickets

Total amount of funds using the function :

f(100)= 5×100-320

=500-320

= $180

Answer:

The slope of the function is 5, and it represents the price of each ticket .

The velocity after 5s s is 20

Answer:

n=15

Step-by-step explanation:

300/20=15

n=15

Answer:

n = 15

Step-by-step explanation:

I took 300 and divided it by 20 to find n.

300 / 20 = 15

To check the answer, I completed this;

20(15) = 300

300 = 300

Answer:

change it into slope intercept form: y=3/2x-5

Step-by-step explanation:

the slope is 3/2

Answer:

m = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

This is the answer because:

1) Use the slope-intercept form: y = mx + b to find the slope

1. The slope intercept form is y = mx + b where m is the slop and b is the y-intercept.

2. Subtract 3x from both sides of the equation:

-2y = 10 - 3x

3. Divide each term by -2 and simplify:

[tex]y=\frac{3}{2} -5[/tex]

4. Using the slope-intercept form, the slope is [tex]\frac{3}{2}[/tex]

Therefore, the answer is [tex]\frac{3}{2}[/tex]

Hope this helps! :D
