Answer:
(-3, -2)
Step-by-step explanation:
To find the solution of two functions, you need to know at which x and y value they are equal. So solve for x and y when 1/3x - 1 = 2x + 4
1/3x - 1 = 2x + 4
First, subtract 2x from both sides.
-5/3x - 1 = 4
Add one to both sides.
-5/3x = 5
Multiply both sides by the reciprocal of -5/3 (3/-5)
x = -3
Then, substitute x into one of the equations to get y.
1/3(-3) - 1
-1 - 1 = -2
So drag the dot to the point (-3, -2)
We have that
the total <span>sold tickets is -------------------------- >600
</span>
the probability of winning with 1 ticket
<span>P=1/600=0.001667---------------- > 0.17%
</span>the probability of winning with 8 ticket
P=(1/600)*8=0.0133---------------- > 1.33%

the answer is </span>1.33%<span>

F(x) =
2x² - 8x + 7=2(x²-4x) + 7
We are going to use formula a²-2ab+b² = (a-b)² to complete the square.
f(x)= 2(x² -2*2x+2²-2²)+7
f(x)=2(x² -2*2x+2²) -2*2² +7
f(x)=2(x-2)²- 1
Answer is D.
We can see that f(x) =
2x² - 8x + 7 and f(x)=
2(x-2)²- 1 are the same on the graph.
