Answer:
The value of
which makes the equation true.
Step-by-step explanation:
Given the equation

We have to find the value of r for which the equation must be true.
solving the equation

Multiply both sides by -11


Therefore, the value of
which makes the equation true.
<u>VERIFICATION:</u>
Putting
in the equation


∵ 
L.H.S = R.H.S
Therefore, the value of
which makes the equation true.
C) six times log base two of x times seven times log base two of y minus log base two of eight.
Answer: 38
Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.
Plugging in -1 for y and -19 for z gets you this:
-2(-1)^2(-19)
Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)
-1^2 = 1
-2(1) = -2
-2(-19) = 38
Your answer is 38
