Answer:
The answer is B) 1/25
Step-by-step explanation:
This is because given that f(x) = 5^x
Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25
Because a^-b can be written as 1/a^b
Answer:
none
Explanation:
Fill in each option for x individually.
I) 9
-10 - 4(-1)
II) 9
-10 - 4(-3)
III) 9
-10 - 4(-2)
Then, simplify the right side of each inequality.
I) 9
-6
II) 9
2
III) 9
-2
Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.
It’s -63 all you would be multiple like normal 63 which then you put a negative symbol on front
4.2x - 1.4y = 2.1
-1.4y = -4.2x + 2.1
y = (-4.2/-1.4)x + 2.1/-1.4
y = 3x - 1.5 <==
Answer:


Step-by-step explanation:
Given the matrices


Calculating AB:

Multiply the rows of the first matrix by the columns of the second matrix


Hence,

Therefore,
