Answer:
131x
Step-by-step explanation:
7x² + 6x + 9x² - 5x
49x + 6x + 81x - 5x
136x - 5x
131x
Answer: m=44
Step-by-step explanation:
1/2m-3/4n = 16
1/2m-3/4(8) = 16
1/2m-24/4 = 16
1/2m-6 = 16
1/2m = 22
m=44
Answer:
a) E = 2482.90
b) 99% Confidence interval: (41510.1,46475.9)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
=$43,993
Sample size, n = 90
Alpha, α = 0.051
Sample standard deviation, s = $9,144
a) The margin of error
Formula:
b) 99% Confidence interval:
Putting the values, we get,
Hey!
------------------------------------------------
-x = -1
This statement shows that y equals -1. Since it doesn't show a table or word problem then we already know that the constant of proportionality is -1. Or if you just have the expression just divide the number by 1. -x/1 = -1!
------------------------------------------------
Thus, -1 is the constant of proportionality!

Hope This Helped! Good Luck!
Hey there! I'm happy to help!
We want to multiply x-6 by 5. To do this, we multiply each term inside by 5.
5(x)=5x
5(-6)=-30
So, our simplified expression is 5x-30.
Have a wonderful day ! :D
