Answer:
The third graph.
Step-by-step explanation:
The equations for the lines will be
P(x) = 2x-4
l(x) = -2x-4
When x = 0 both of these functions equal -4. The only graph where this happens is the third one.
You can check this by looking at the slopes and plugging in points.
Answer:
x = -15
Step-by-step explanation:
Step 1: Write equation
3(2x - 5) - 3(x - 7) = 2x - 9
Step 2: Distribute
6x - 15 - 3x + 21 = 2x - 9
Step 3: Combine like terms
3x + 6 = 2x - 9
Step 4: Subtract 2x on both sides
x + 6 = -9
Step 5: Subtract 6 on both sides
x = -15
Just Put -8 in for X 4(-8)+5 goes to -32+5 to 27
Answer:
original price = $129
20% discounted price = $103.2
adding 7% sales tax = $110.424
OPTION B = 110.42
Answer: $63.16
<u>Step-by-step explanation:</u>
Probability of winning is 
. Which means that it would take 38 spins to win one time.
Since the average player spins 60 times then the number of wins is:
= 1.58
So, the average person wins: ($700 + $20) x 1.58 = $720(1.58) = $1136.84
and the average person spends: $20 x 60 spins = $1200.00
The net gain for the house is $1200.00 - $1136.84 = $63.16
