Consider the function f(x)=-2x+5 what is f(5) enter your answer in the box

Oliga [24]

The value of f(5) is $f(5)=-5$

Step-by-step explanation:

The function is $f(x)=-2x+5$

To find $f(5)$ substitute $x=5$ in $f(x)=-2x+5$

$f(5)=-2(5)+5$

Multiplying the terms, we get,

$f(5)=-10+5$

Adding the terms, we get,

$f(5)=-5$

Thus, the value of $f(5)$ is $f(5)=-5$

Adjacent i need help understanding this

Cerrena [4.2K]

Answer:

The definition of adjacent in math can mean a couple of different things. For angles, adjacent angles would be any two angles that share a side. In other words, two angles right next to each other.

A more broad meaning is just any two geometric shapes that are next to each other in a figure.
