Answer:
B
Step-by-step explanation:
Answer:
C. 
Step-by-step explanation:
To find the value f b, we need to compare the exponents.
The given exponential equation is:
Recall and apply the following rule of exponents.
We apply this rule on both sides to get:
Simplify the exponents on the left.
Comparing exponents of the same variables on both sides,
Divide both sides by 6.
Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer
when using 3.14 for pi
Woops: forgot to add the diameter of 12 so we would have 30.84
Substitute each value until the answer is correct
a. 1 = -4 x -5 -1
1 does not equal 19
b. 15 = -4 x 4 -1
15 does not equal -17
c. -5 = -4 x 1 -1
-5 equals -5
just to make sure the last answer is incorrect
d. -7 = -4 x 2 -1
-7 does not equal -9
