PLEASE HELP ME ASAP!!

point slope form means (y-y1)=m(x-x1)

so u need to find the slope gradient from those 2 points

m=y2-y1/x2-x1

=-6-6/11-7

=-12/4

=-3

and finally x1,y1=7,6

(y-y1) =m(x-x1)

(y-6) =-3(x-7)

What is the value of the expression? 8 x (-4.8) divided by (-4)

valentina_108 [34]

The answer is D.9.6. This is because you multiply 8 x (-4.8)= -38.4 and since you divided it by another negative it becomes positive. Hope this helped.

Determine the value of g(4), g(3 / 2), g (2c) and g(c+3) then simplify as much as possible.

jeka94

Answer:

$g(4) = 8 \pi h\\\\g(\frac{3}{2}) = 3 \pi h\\\\ g(2c) = 4 \pi ch\\\\g(c+3) = 2 \pi hc+6\pi h$

Step-by-step explanation:

You need to substitute $r=4$ into $g(r) = 2 \pi r h$ . Then:

$g(4) = 2 \pi(4)h\\\\g(4) = 8 \pi h$

Substitute $r=\frac{3}{2}$ into $g(r) = 2 \pi r h$ . Then:

$g(\frac{3}{2}) = 2 \pi(\frac{3}{2})h\\\\g(\frac{3}{2}) = 3 \pi h$

Substitute $r=2c$ into $g(r) = 2 \pi r h$ . Then:

$g(2c) = 2 \pi(2c))h\\\\g(2c) = 4 \pi ch$

Substitute $r=c+3$ into $g(r) = 2 \pi r h$ . Then:

$g(c+3) = 2 \pi (c+3)h\\\\g(c+3) = 2 \pi hc+6\pi h$
