Question

evaluate the expression if (t = 3). (|t - 3|-7)

Explanation:

Step1: Substitute t value

Substitute $t = 3$ into $|t - 3|$.
$|3 - 3|$

Step2: Calculate absolute - value

Calculate $|3 - 3|$. Since $3-3 = 0$, then $|3 - 3|=|0| = 0$.
$|0|=0$

Step3: Subtract 7

Subtract 7 from the result of the absolute - value calculation.
$0-7=-7$

Answer:

$-7$
