first you combine like term
3x+12x=2
15x=2
then you divide 15x by 2
x=7.5
I hope that's the answer
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.
To isolate b, add a and subtract c to the entire equation:
D - a + c = -b
Muliply b by -1 to eliminate the negative:
-D + a - c = b
Answer:
The angle is 28.
Step-by-step explanation:
If we consider the system below (were "A"is the angle):
A + [(x/2)-14] = 90 (complement)
A + x = 180 (suplement)
We can isolate "X=180 - A" and apply this in the first equation. This way we are able to have only one variable, and w'll see that A=28.
5 8/10 or 58/10
10x5=50+8=58
They are equal
