Answer & Step-by-step explanation:
(26 - 3)(-6)
Subtract 3 from 26 first.
(23)(-6)
Now multiply 23 by -6.
-138
So, (26 - 3)(-6) equals -138.
We are given:
the center of the rink at the origin.
A skating path (Susan): y = 6x - x^2 - 5
Starting point of Luke = (10, -21)
Path (Luke) = quadratic eq'n with vertex at (8, -9)
Radius = 35 meters
The solution that best interprets the path of the skaters is to substitute Luke's starting point to Susan's path or set-up a quadratic equation with vertex of (8,-9) and then equate to Susan's path to solve for their intersection.
First we want to get them into similar terms so it makes more sense.
Let's go for mph since that is more common.
40 mph
50fps (feet per second)
To get this into mph we divide it by 1.467
34 mph - ish
So I would not mind either as they are quite similar in speed :)
(unless I am abosultely wrong haha)
Answer:
-4
Step-by-step explanation:
7w + (-11w)
Postive negative negative
7w-11w
= - 4
