Please rewrite your question so it makes sense.
Good Luck! :D
Answer:
A) y = x^2 -1
B) -y = 2x^2 +1 We multiply B) by -1
B) y = -2x^2 -1
We can then say x^2 -1 = -2x^2 -1
3 x^2 = 0
x = 0
************* Double-Check: ******************
Equation A) y = -1 and
Equation B) y = -1
Step-by-step explanation:
To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
A safe bet would be to go from 0-70 with increments of 2.
