Answer:
When they are equal, y=y, so we can say:
x^2+5x-2=x+1 subtract x from both sides
x^2+4x-2=1 add 2 to both sides
x^2+4x=3, now add half the linear coefficient squared, (4/2)^2=4
x^2+4x+4=3+4 now the left side is a perfect square
(x+2)^2=7 now take the square root of both sides
x+2=±√7 subtract 2 from both sides
x=-2±√7
x=-2+√7 and -2-√7
y=x+1 the two points where these equations are equal are:
(-2-√7, -1-√7) and (-2+√7, -1+√7)
or approximately:
(-4.65, -3.65) and (0.65, 1.65)
1/2
If there is one head and one tail for each coin the probability would be 1/2. There are two terms with only one answer 1/2.
OR
If you are asking for the end result of heads and the coins you would get 2/3. There are three terms with only one answer. 2/3.
Answer:
7
Step-by-step explanation:
Subtracting the equations yields that m=2, and thus c=3.
