Question 4: true?
question 5: true
Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.
Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500
Answer: d
(-5,3)(5,7)
Slope = change in y /change in x
M= 7-3/5-(-5)
M= 4/ 10
M=4÷2/5÷2
M=2/5
Your slope is 2/5 in fraction form or 0.4 in decimal form
That is a numerical expression. If it was an equation, it would have an equal sign.
