Answer:
f(-2) = 9
Step-by-step explanation:
Given that,
f(x) = x² + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2)² + (-2) + 7
= 4-2+7
= 9
Hence, the value of f(-2) is equal to 9.
Answer:
Cost of the coat = $54
Step-by-step explanation:
Given:
She saved = $ 9
To Find:
Cost of the coat = ?
Solution:
Let the price of coat be x
She saved $9

by this we have
Multiplying both sides by 6
it becomes
x = 9*6
x = $54
As x is the amount she needs
so
Cost of the coat = $54

Answer: √5
2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.
-3 is a rational number because it's an
integer and all integers are rational.
√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.
√5 is no rational! It's impossible to find a whole number multiplied by itself to give us 5 which means that it's
non-terminating and non-repeating.
