There is no solution. Because the absolute value function finds the distance between the number and 0. And length is never negative.
So, |-x| = -10 has no solution.
It would be : -9.3 , -4.125 and -2.25.

Good Luck Studying :)
Answer: 7
Step-by-step explanation: it just makes sense
Answer:
k = -9.
Step-by-step explanation:
As the triangle is right-angled at Q, by Pythagoras:
PR^2 = PQ^2 + RQ^2
So, substituting the given data and using the distance formula between 2 points:
(7 - 1)^2 + (k - 4)^2 = (-4-4)^2 + (-3-1)^2 + (7 - (-3))^2 + (k - (-4))^2
36 + (k - 4)^2 = 64 + 16 + 100 + ( k + 4)^2
(k - 4)^2 - (k + 4)^2 = 180 - 36
k^2 - 8k + 16 - (k^2 + 8k + 16) = 144
-16k = 144
k = -9.
64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.
