Answer:
k = +10 or -10
Step-by-step explanation:
It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.






Answer:
Step-by-step explanation:
Split it into 2 inequalities:
-8 < y + 2x
y + 2x < 14
Isolate y , subtract 2x from first and then from second
-8 -2x < y
y < 14 -2x
Rewrite it so it looks pretty?
y > -2x-8
y < -2x +14
You can use the calculator to graph each inequality.
The solution or the system is the area where the 2 solutions for each line overlap.

12 times 8 divided by 2. (12*8)/2 Answer is 48.
The answer is 1 n 1/3 because 9 divided by 3=3 so that means their 3 times less than the other figure, so than you do 4 divided by 3 and you get 1 n 1/3
