Answer:
is not equal to 
Step-by-step explanation:
When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.
For example
and 
So

wich is clearly not equal to 0.000002015
the correct scientific notation for 0.000002015 must be:
With a negative in the power of 10, referring to a small quantity.
8 1/3% would be equal to 25/4%
Answer:
The equation would be y = x - 1
Step-by-step explanation:
In order to find the equation of the line, we first can express the two sets of data as an ordered pair. The two ordered pairs would be (3, 2) and (9, 8). Now that we have these, we can use the slope formula to find the slope.
m (slope) = (y2 - y1)/(x2 - x1)
m = (8 - 2)/(9 - 3)
m = 6/6
m = 1
Now that we have the slope, we can use either point and point slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = 1(x - 3)
y - 2 = x - 3
y = x - 1
Answer:
Step-by-step explanation:
square root of 121 is11
square root of x^2 is x
so 11x
D: x ≥ 0
7 < √x < 8 ⇒ 7² < x < 8² ⇒ 49 < x < 64
Answer: x = 50 or x = 51 or x = 52 or ... or x = 63.
