Question

quiz 1
k(x) = 6x + 100
k(-5) = \boxed{}

Explanation:

Step1: Substitute x with -5

To find \( k(-5) \), we substitute \( x = -5 \) into the function \( k(x) = 6x + 100 \). So we get \( k(-5)=6\times(-5)+100 \).

Step2: Calculate the multiplication

First, calculate \( 6\times(-5) \). We know that a positive number multiplied by a negative number gives a negative result, so \( 6\times(-5)= -30 \).

Step3: Calculate the addition

Now, substitute the result of the multiplication back into the expression: \( -30 + 100 \). When we add a negative number and a positive number, we subtract the absolute values and take the sign of the number with the larger absolute value. Here, \( 100 - 30 = 70 \), and since 100 has a larger absolute value and is positive, the result is 70.

Answer:

70
