Hello! The simplest fraction would be: 4/5
I really hope this helped you! c:
The points of intersection are at (3, 6) and (-1, -2).
Since both of these equations have y isolated, we can set them equal to each other:
2x=x²-3
We want all of the variables on one side, so subtract 2x:
2x-2x = x²-3-2x
0=x²-3-2x
Write the quadratic in standard form:
0=x²-2x-3
This is easily factorable, as there are factors of -3 that will sum to -2. -3(1)=-3 and -3+1=-2:
0=(x-3)(x+1)
Using the zero product property we know that either x-3=0 or x+1=0; therefore x=3 or x=-1.
Substituting this into the first equation (it is simpler):
y=2(3) = 6
y=2(-1)=-2
Therefore the coordinates are (3, 6) and (-1, -2).
Right triangle always has the Hypotenuse as the longest side which means the other two in this case are 20 m long. We can calculate the length of hypotenuse by using Pythagoras Theorem
a = (b^2 + c^2)^0.5
a = (20^2 + 20^2)^0.5
a = 28.28
Thus Perimeter = a + b + c = 28.28 + 20 + 20 = 68.28 m
Desce 3 , sobe 5 pra esquerda, joga um 2 pra lá, e tbm desce sua tia quicando na minha banana! MUAHAHA
Answer: 20
Step-by-step explanation:
Given
The cost of an individual ticket is $25
The cost of a couple's ticket is $40
The total sale is $2500
total ticket sold is 70
Suppose there are x individuals and y couples
So, they sold 20 tickets of the individual.
