Answer: D. x= -5 1/2, y= -3 1/4</h3>
==============================================================
Explanation:
The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate
Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.
2/3 x (9+12) is 14. Hope it helps :)
Answer:
a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm. so around 21.

Answer:
x=-2
Step-by-step explanation:
Step 1: Subtract 8x from both sides.
5x+6−8x=8x+12−8x
−3x+6=12
Step 2: Subtract 6 from both sides.
−3x+6−6=12−6
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6
−3
x=−2
Answer:
1/n^12 or n^-12
Step-by-step explanation:
=n^-10 / n^2
=1/n^10 / n^2
=(1/n^10) *(1/n^2)
=1/n^12
