He is incorrect. When involing cubes, it would be 5*3, it would be 5^3 or 5*5*5. Hope this helps
Answer:
it is it is 42
Step-by-step explanation:
7/42+12/42=19/42
The plotted point will be reflected across the y-axis.
The graph of line 3x-y= -1 will be as follows.
What is a line?
A line is an endlessly long, straight object that, despite being drawn with a minimum width, is considered to have no particular width in mathematics.
Main Body:
slope = m = 3 point = (0,1)
The formula for one point form for a line is -
y-y₁ = m(x-x₁)
y- 1 = 3(x-0)
3x-y =-1
Now the graph for the line will be plotted by using the point given and the slope--
on Graph mark the point (0,1)
