Answer:
f(-2) = 3
Step-by-step explanation:
Given that,
f(x) = x + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2) + (-2) + 7
= -2-2+7
= -4+7
= 3
Hence, the value of f(-2) is equal to 3.
Answer:
Step-by-step explanation:
Take the log of both sides.
Use properties of log.
Answer:
2.25
Step-by-step explanation:
1.5 x 1.5 = 2.25
ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
