Answer:
x = ± 10
Step-by-step explanation:
To solve the equation let y = 0 , that is
0 = 100 - x²( add x² to both sides )
x² = 100 (I take the square root of both sides )
x = ± 
= ± 10
Then solution is x = - 10, x = 10
The answer will be 1/2 because in a coin there is heads and tails. So, its 50% chance to get either one. Now, for 2 coins there will be heads, tails, head, and tails. The question ask you for tails so there are 2 ways to get tails. Also, the total of the two coins to get either heads or tail is 4. You should get 2/4 which is 1/2.
Y=Mx+b
M=3
Now you need b, so plug the x-coordinate and y-coordinate into the x and y in the equation to find the b.
-5=3(-3)+b
-5=-9+b
Add 9 to both sides to isolate the b
-5=-9+b
+9. +9
4=b
So the equation is
Y=3x+4
