x=2, y=3
Step-by-step explanation:
Answer:
If i'm not mistaken the answer should be a 35% discount.
Step-by-step explanation:
Answer:
c<-3
Step-by-step explanation:
move the constant to the right-hand side and change its sing
Then canculate the difference
Then divide both sides for the inequality of 3
Step-by-step explanation:
8x+3y=18
subject y according y=mx+c
y=8/3x-6
(-9,-13)
substitute -9 to y=8/3x-6
-13=8/3×(-9)+c
11=c
y=8/3x+11

so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
