Answer:
3.124*
Step-by-step explanation:
In order to find the scientific notation of a number, you must move the decimal point to the right of the first significant (not 0) number. In this problem, you have to move the decimal 4 points to the right, which means that you would multiply the resulting number by ten to the negative fourth. If you were to move the decimal four points to the left, you would multiply the resulting number by ten to the fourth instead.
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m = =
=
Using (a, b ) = (9, 3 ) , then
y - 3 = (x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) = (x - (- 3) ) , that is
y + 6 = (x + 3) → D
Answer:
Slope = - 8
