Step-by-step explanation:
Greetings !
simplify for variable y first
apply exponent rule
Add/subtract the numbers -8+3=5
Apply exponent rule
Thus,
secondly, simplify for the variable x
Apply exponent rule as we made on y
multiply bot the values we get
Hope it helps!
Answer:
Weak Positive Correlation
Step-by-step explanation: I think that’s correct not 100 percent sure
Slope intercept form is y = mx + b
Pick one of the coordinates, I’ll use (-3,-4) as the example.
Coordinates are just numbers plugged in for (x,y).
This means -3 would be your x and -4 would be your y.
So plug these numbers into the equation and you get -4 = m(-3) + b.
M is slope and to find slope, you need to do (y2-y1) / (x2-x1).
In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).
Now plug that in for m to get the b variable.
-4 = 1/7(-3) + b.
B = -3.57
Your answer is y = 1/7x -3.57
To get a number to decrease by 21% you multiply it by 0.79 (1-0.21)
r = 0.79
