Question

is r = 4 a solution to this equation? -249 = -10|-4 - r| yes no

Explanation:

Step1: Substitute r=4 into equation

Substitute $r=4$ into $-249 = -10|-4 - r|$:
$\text{Right-hand side} = -10|-4 - 4|$

Step2: Simplify absolute value term

Calculate the value inside the absolute value:
$-10|-8| = -10\times8$

Step3: Compute final right-hand value

Perform the multiplication:
$-10\times8 = -80$

Step4: Compare both sides

Left-hand side is $-249$, right-hand side is $-80$. $-249
eq -80$.

Answer:

no
