10w-8+6-4w is equal to 6w-2
2(3w-1) = 6w-2
6w-2
(11w-1)-(5w+3)=11w-1-5w-3=6w-2
3w+7+3w-9 = 6w-2
Hope this helps
If two angles are supplementary, their measures add to 180 degrees.
Let’s name the angles A and B.
You can substitute or replace angle B in the first equation with the second equation like so:
4
So, angle A is 42.5 degrees and angle B is 137.5 degrees!

Vector Functions and Parametric Equations
A bow-and-arrow hunter walks toward the origin along the positive x-axis, with unit speed; at time 0 he is at x = 10. His arrow (of unit length) is aimed always toward a rabbit hopping with constant velocity √5 in the first quadrant along the line y = 2x; at time 0 it is at the origin.
a) Write down the vector function A(t) for the arrow at time t.
b) The hunter shoots (and misses) when closest to the rabbit; when is that?

<u>Given:</u>
- Total distance is 500 km
- Total time is 5 1/2 h
- The distance travelled at 100 km/h is x
- The distance travelled at 80 km/h is y
