is the intercept form of the equation.

Now we know the two points on the line as

(

By plotting the two points on a graph sheet and joining them gives the line required.

Answer:

I’m not too sure what your question is exactly but if your just trying to graph the two equations I can help u with that (:

Step-by-step explanation:

The first thing you should do is change the second equation to slope intercept form. It is much easier for most people. From there write out your table by choosing a number for x then plugging that number into the equation to find y. For the first equation (y=1/3x+2) it’s always easier to use multiple of three for the number of x. For example, if 3 was my number for x I would multiply 1/3 by 3=1 then simply add 2=3. So the coordinates for one point on that table would be 3,3. You continue to do that for each graph then plot your points. (In my graph, purple is the equation y+9=-9/3x-9 and black equals the equation y=1/3x+2

In a different dimension, cows have $x+3$ legs, with 3 toes on each leg. Chickens have $2x-4$ legs, with 7 toes on each leg. If
Juli2301 [7.4K]

Answer:

20x-10

Step-by-step explanation:

Cows have x+3 legs and 3 toes on each leg, if we want to find the number of toes of ONE cow we have to multiply the legs by the toes giving the following:

3(x+3) \quad (1)

But we have two cows so (1) we have to multiply it by 2 giving a total of:

2(3(x+3))\\6(x+3)\\6x+18 \quad (2)

By the other hand chickens have 2x-4 legs and 7 toes on each leg, if we want to find the number of toes we have to multiply the legs by the toes giving the following:

7(2x-4)\\14x-28 \quad (3)

To find the total amount of toes we have to add (2) and (3)

(6x+18)+(14x-28)\\20x-10

A circle has a circumference of 45 cm. What is the BEST estimate of the circle’s diameter?
ch4aika [34]

Answer:

C) 15 cm is the best estimate.

Step-by-step explanation:

The exact answer is not there, so 15 is the best estimate.

You can use this equation to help you:

d=C/π

Where d is the diameter.

C is the circumference.

And the last one is Pi.

You know that C = 45, so divide that by Pi (3.14).

45/3.14159 = 14.32

The closest answer is 15.

Hope this helps! Have a great day!
