Answer:
y=120
Step-by-step explanation:
y=0.75x-0.15x
x=200
y=0.75x200-0.15x200
y=150-30
y=120
I hope this helps :D
Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.
Not sure, if correct but here.
5=2n - 3
you have to add 3 on both parts so that you can take eliminate the three on the right side. doing so, means you have to add 5+3 which equals 8. You then have to get 'n' alone and to do that you have to divide the 2 with 2n so that the n will be alone. but, you have to do it on both sides which means it will be 8/2. which solves for
n = 4
