Answer:
27
Step-by-step explanation:
sub in the letters with the given number in brackets
= (9) + 6(3)
= (9) + 18
= 27
Answer:
<em>u</em> = 7.21
Step-by-step explanation:
The magnitude of <em>u</em> is just the distance between the two points. The coordinates of the left-most point are (-2,-8) and the coordinates of the right point are (4, -4). I'm assuming the x coordinates here because we don't actually know the scale.
Ok so from these points, you can draw a triangle (u can see it in the attached file).
From the coordinates we can tell the lengths of the sides, and the triangle shows that <em>u</em> is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of <em>u</em>.

Since c = <em>u</em>, we know now that the magnitude of <em>u</em> is 7.21
Hope this helps!
Answer:
is this even a equation
Step-by-step explanation:
Answer:
-7-y1=-4(2-x1)
Step-by-step explanation:
Point slope form is like this: y-y1=m(x-x1) where y is the y value, x is the x value, and m is the slope. You plug the values in.
