Answer:
(0, -1)
Step-by-step explanation:
There are multiple ways of solving this however- since both equations are already in Y-Intercept form, we will use the "Equal Values Method"
First, since both equations are equal to Y, we can set them equal to each other and solve for X

To start, you must eliminate the fraction using a "fraction buster" multiply EVERYTHING by 4 then simplify.

Since we still have a fraction, we shall do it one more time. This time we multiply by 3

Now, solve how you normally would.
9x = 6x
-6x
3x = 0
X = 0
Now, since we know what X would equal in the solution, we are able to plug in X as 0 in one of our equations. We can choose the first one!

Now solve which would lead to y = -1
You have your solution as
(X,Y)
(0,-1)
Hope this helps!
Answer:
10
Step-by-step explanation:
40=2 x 2 x 2 x 5
50=2 x 5 x 5
therefore, GFC = 2x5
GFC= 10
Answer:
The Choice N#1 will give more pizza for your money
Step-by-step explanation:
step 1
Find the area of one slice Choice #1
The area of the circle is equal to

we have
----> the radius is half the diameter
assume

The area of one slice is equal to

substitute


Divide the cost by the area

step 2
Find the area of the entire personal pizza Choice # 2
The area of the circle is equal to

we have
----> the radius is half the diameter
assume

substitute


Divide the cost by the area

therefore
The Choice N#1 will give more pizza for your money
