Answer:
X=12
Step-by-step explanation:
Khan Academy
Normally you would only solve by completing the square if a is 1 and b is even. But the answer would be half of b. So half of 9 is 4.5 or 4(1/2).
Since the two lines are parallel, the angle labeled 130 is congruent to the angle labeled x+ 136 so you can set them equal to each other
130 = x + 136
subtract 136 from both sides
x = -6
Answer:
36 Treats
Step-by-step explanation:
The dog trainer started with a bag of 60 treats.
The dog trainer gives treats to 8 dogs with 3 treats meaning 8x3= 24
The trainer gave a total of 24 treats to the 8 dogs.
If the trainer had 60 treats at the start minus 24 (60-24=36).
That means the trainer now has a total of 36 treats left.
Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ], thus
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8
average rate of change = 
= 
= 34
