We can change the negative sign into i instantly as sqrt-1 is i.

With this the problem simplifies to sqrt48*i.

Now sqrt48=sqrt4*sqrt4*sqrt3=2*2*sqrt3

So the final product is 4sqrt3*i=4isqrt3.

Thus choosing choice 3 :)

Two points on the line are (0, 4) and (7, 18). Use the points to first determine the slope and y-intercept. Then write the equat

Answer:

a. m = 2; y intercept = (0, 4); y = 2 x + 4

Step-by-step explanation:

The slope can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

m = (18 -4)/(7 -0) = 14/7

m = 2

The y-intercept is the first given point: (0, 4).

The equation for the line in slope-intercept form is

y = mx + b

Here, we have m=2 and b=4, so the equation is ...

y = 2x +4
