Question

What is the output for the rule “seven increased by five times a number,” if your input is negative two?(2 points)

Answer 1

To find the output for the rule "seven increased by five times a number," you can express it mathematically as:

\[ 7 + 5x \]

where \( x \) is the number you're providing as input. In this case, \( x = -2 \).

Now, substitute \(-2\) for \(x\):

\[ 7 + 5(-2) \]

Calculate the multiplication first:

\[ 5(-2) = -10 \]

Now, substitute that back into the equation:

\[ 7 - 10 \]

Finally, calculate the result:

\[ 7 - 10 = -3 \]

So the output for the given rule and input is \(-3\).
