rounding 2.289 to the nearest ten gives you 0. its that simple ;)
A would be 0,
0 divided by 4 =0
0/4=0
It would be 9.
the original equation y=x^2 - 2x + 3 is multiplied by 3, as the scale factor is 3.
Answer:
The solution would be (5, -2)
Step-by-step explanation:
To use this method, start by multiplying the second equation by -1. Then add the two equations together.
9x + 5y = 35
-2x - 5y = 0
------------------
7x = 35
x = 5
Now that we have the value of x, use it to solve either equation for y.
2x + 5y = 0
2(5) + 5y = 0
10 + 5y = 0
5y = -10
y = -2
The "mean" is just the regular arithmetic average:
sum of all terms / number of terms...
In this case:
(32+33+34+34+36+38+38+38+40+42)/10
36.5
