Answer:

f(-15) = -60

Step-by-step explanation:

Plug in -15 for x:

f(x) = 4x; f(-15) = 4(-15)

Multiply. Note that when you multiply one negative and one positive number together, your answer will be negative.

4 * -15 = -60

-60 is your answer.

Given 6(x) = (x+41, what is b(-10)?

prisoha [69]

The value of $b(-10)$ is 31

Explanation:

The given expression is $b(x)=x+41$

We need to determine the value of $b(-10)$

The value of $b(-10)$ can be determined by substituting $x=-10$ in the expression $b(x)=x+41$

Thus, we have,

$b(-10)=-10+41$

Adding the terms, we have,

$b(-10)=31$

Thus, the value is 31.

Therefore, the simplified value of the expression by substituting $x=-10$ in the expression $b(x)=x+41$ is 31.
