Answer:
3i-1
Step-by-step explanation:
2+3i-3
3i-1
I believe this is an inequality because this doesn’t pass the origin point 0
Does not pass 0,0
If I’m wrong so sorry
Answer:
550
Step-by-step explanation:

Answer:
<h2>V = 27m³</h2>
Step-by-step explanation:
We know: All faces of a cube are squares.
The formula of an area of a square with a side <em>s</em>:
<em>A = s²</em>
We have <em>A = 9m²</em>
Substitute:
<em>s² = 9 → s = √9 = 3 m</em>.
The formula of a volume of a cube with an edge <em>s</em>:
<em>V = s³</em>
Substitute:
<em>V = 3³ = 27 m³</em>
Answer: The regression equation could have a positive or a negative slope
Explanation:
The coefficient of determination is marked as r^2. This is always positive because squaring a negative leads to a positive. Knowing something like r^2 = 0.7 does not tell us whether r itself is positive or negative, so we don't know if the regression line slope is positive or negative. We would need more info.
