Answer:
y = -(2/3)x + 3
C
Step-by-step explanation:
The slope of the equation that was given is - 2/3
The slope in a slope intercept equation is the number in front of the x when the value of the number in front of the y = 1 and x and y are on opposite sides of the equal sign. Let's translate that.
The original equation is y = -(2/3)x + 5/3
- y and x have to be on opposite sides of the equal sign [They are]
- The slope is the number in front of the x. That's (-2/3). That makes A incorrect.
Now you need to use the given point
The point is (-3 , 5) Put this into the equation that you have so far
y = (-2/3)x + b
y = 5
x = -3
5 = (-2/3)(-3/1) + b Substitute in the givens
5 = (-2 * -3)/3 + b Multiply -2 * - 3 = 6
5 = 6/3 + b Divide the 6 by 3
5 = 2 + b Divide
5 - 2 = b Subtract 2 from both sides
3 = b Switch sides
b = 3
Answer y = (-2/3)x + 3 or C
I got -3.........................
-7 - 7p = 3p + 23
Move the -7p over to the right....by adding
-7 = 10p +23
Move the 23 over to the left by subtracting
-30 = 10p
divide by 10
p = -3

Answer:
10%
Step-by-step explanation:
Since the question is not complete, I will be solving for probability of 3 9s
To solve this, we would be using the principle of combination, and thus
A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )
Remember I told us were going to be using the principle of combination. Well then
nCr = n!/r!(n - r)!
Now, applying the above stated formula to the equation, we have
48C10 = 48!/10!(38!)
4C3 = 4!/3!(1!)
52C13 = 52!/13!(39!)
48C9 = 48!/9!(39!)
4C4 = 4!/4!(0!)
Solving for each independently, we find that
= 0.0412 + 0.588 = 0.1
