Unless this is some perplexed kind of math, how can you solve the variables when there is only one number to go from?
Is there a 'not enough information' answer choice
I tried every combination. there seems to be something wrong with the informations you gave.
the second equation contains errors, and none of these 4 points can be solutions to the first equation alone
Answer:
Let the midpoint be M(x,y).
7) x= (3+1)/2= 4/2= 2
y= (-9+5)/2= -4/2= -2
M(2,-2)
8) x= (5-6)/2= -1/2= -0.5
y= (-1-3)/2= -4/2= -2
M(-0.5,-2)
Answer:
Step-by-step explanation:
Because MK is a diameter, then angle L is a right angle. We already know that the measure of angle K is 50, so the measure of angle M has to be 40 because of the triangle angle-sum theorem. The rule for inscribed angles and the arcs they cut off is that the angle is half the measure of its intercepted arc or, likewise, the arc is twice the measure of the angle that cuts it off. Since arc LK is across from angle M and is cut off by angle M, then arc LK is twice the measure of angle M, and is 80. That's the same reason why angle L is 90; arc MK is a semi-circle, with a degree measure of 180, and angle L is half of that.
Arc LK = 80
Answer: The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%.
