Answer:
B .4
Step-by-step explanation:
Hope this is your answer
Step-by-step explanation:
<u>Step 1: Add (-9)/8 to both sides.</u>
(21/4) ^x + 9/8 = 2
(21/4) ^x + 9/8 + -9/8 = 2 + -9/8
(21/4) ^x = 7/8
<u>Step 2: Solve Exponent.</u>
(21/4) ^x = 7/8
x = log (7/8) by log (21/4)
x=−0.080527
Explanation in words:
The first step is to Add (-9)/8 to both sides of the question. In the end, the answer will result as (21/4) ^x = 7/8.
The second step is to solve the equation by using log. Formula for log is log = x. For base. At the end we solve all the exponents and the answer will end up being x=−0.080527.

Hope this helps.
Total number of seats = 5
Total number of friends = 5
We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.
5P5 = 120
So, the 5 friends can sit in 120 different ways.
The correct answer is option D
Is this the same q i just answered
Answer:
1/3
Step-by-step explanation:
gradient or slope = m
m = change in y ÷ change in x
= (-4 - -2) ÷ (-3 - 3)
= (-4 + 2) ÷ (-3 - 3)
= -2 ÷ -6
= 1/3
