Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
Answer:
- 16
Step-by-step explanation:
This is very tricky. Be careful how you do it.
The total of the six numbers is 6*41 = 246
The total of five numbers = 5*46 = 230
What have you you removed to make the number average go up with a smaller sample? The answer is a negative.
230 - 246 = - 16
Answer:
The equation is y = -6x + 1.33
y = mx + b
-6 is the slope so it goes where the mx is and 4/3 when simplified the y intercept is 1.33.
The total surface area of the cylinder would be 748 sq inches. I have attached a picture of the work in case you need it. I hope this helps. :)
