Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
Step-by-step explanation:
The Pythagorean theorem can be understood as a mathematical relationship between the sides of a right triangle that helps to understand geometric problems in real situations, such as finding measurements, calculating areas, etc.
The theorem says that the square of the hypotenuse is equal to the sum of the squares on the other sides.
In a right triangle the hypotenuse is the longest side of the triangle, on the side opposite to its longest angle, and the other two sides will be the sides. So the Pythagorean theorem formula is:
a² = b² + c²
where a represents the hypotenuse and b and c the other sides.
Answer:
Answer: binomial
Step-by-step explanation:
Two different terms separated by a plus or minus term defines a binomial. You have a binomial.
1/2x is one of the terms.
the minus sign comes next
the 7 is the second term.
