Step 1: group Y on left side
(-2 - 3)y = -5y
step 2: group constants on left side
8 - 9 = -1
step 3: form modified equation
-5y - 1 = 11
step 4: group constants
-5y - 1 + 1 = -11 + 1
step 5: cancel 1 on left side
-5y = -10
step 6: divide each side by -5
-5y/-5 = -10/-5
answer: y = 2
The answer to number 1 is B
First arrange the numbers from least to greatest:
67, 76, 76, 82, 84, 93
The median is the middle number. But since we have two numbers that are in the middle we have to find the average of them.
76 + 82 = 158
158/2 = 79
So your answer is 79
solution:
we are consider the following function,
f(x)=3x+k,x\leq 3
=kx^{2}-6,x>3
\lim_{x\rightarrow 3^-}(3x+k)=9+k
\lim_{x\rightarrow3^+}
(kx^{2}-6)=9k-6
so the left and right limits are equal.
therefore, the function is continuous at x=3
so,the therom of the function is continous at x=3
9k-6=9+k
8k=15
k=15/8
=1.875
therefore,the value of k=1.875
