(-43) x 7 x (-21) = 6,321
Answer:
3
Step-by-step explanation:
f(x) = 2x^2 + 1
f(-1) means that wherever you see an x on the right hand side, you substitute -1.
f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3
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:
Equations 1 & 3 are correct.
Explanation:
Equation 2's actual answer is -8, and Equation 4's actual answer is positive 7.
Answer: The manager should sell the chair for $1740.
Step-by-step explanation:
45% of 1200 Solve this to find the amount increase

$1200 + $540 = $1740
or you could do it this way
100% + 45% = 145%
145% of 1200 =?
