I just plugged all three of these equations into a calculator and A and C both equal 0.
Hope this helped.
Diameter of small pizza = diameter of large pizza divided by 2 = 9 inches
x = y divided by 2
x = 9 inches
Answer:
Step-by-step explanation:
So 8/12 + 7/8 needs to be greater than 1 foot? It is.
8/12 = 2/3
7/8 + 2/3 =
7/8 = 3*7 / 8*3 = 21 / 24
2/3 = 8*2 /8*3 = 16 / 24
Now add them
21 / 24 + 16/24 = 37/24 which is way more than 1 foot.
37/24 = 1 13/24
Answer:
For the first question: y = x^2
For the second question: y = x^2 - 2x + 1
For the third question: y = x^2 + 2x + 1
For the fourth question: y = x
For the fifth question: y = -x
Hope this helps:) Have a great day!
