Answer:
Step-by-step explanation:
8 x 6 = 48 because you just add a 1
The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together.
The second one is almost a straight line so it would be very close to 1. I would say 0.97
The closer the data is to a straight line the closer the r value is to 1 or negative 1.
Hope this helps.
add the two equations together
5a+5b=25
-5a+5b=35
------------------
0 + 10b =60
divide by 10
b=6
5a + 5b = 25
5a +5(6) = 25
5a +30 =25
subtract 30 from each side
5a =-5
divide by 5
a = -1
Answer (-1,6)
or a=-1 b=6
Answer:
A. -5m/5 does not equal m
Step-by-step explanation:
-5m/5 = -m, not m.
In step 2, both sides should be divided by -5, not by 5.
Answer: A. -5m/5 does not equal m
Answer:
