1) Striangle = 1/2 * (12-8) * 4 = 1/2 * 4 * 4 = 8 km^2
2) Srectangle = 4 * 8 = 32 km^2
3) Sfigure = 8 + 32 = 40 km^2
Number C
Answer:
Mistake in step 3
Step-by-step explanation:
3^16/3^-8 should simplify to 3^24 not 3^8
Factorize the quadratic.
We have 
, so
Now, both 
and 
(since the absolute value of any number cannot be negative), so we just need to worry about when the left side is exactly zero. This happens for
So the solution to the inequality is the set
Answer:
He omitted the value "6" from the input value and added it to the output values. Also, he omitted the value "12" as an output value.
Step-by-step explanation:
Bobby didn't map the relation well. He omitted "6" which is supposed to be an input value and rather included it among the output values (y-values).
"12" was omitted also under output values.
All of these make the the relation not to be a function anymore.
If Bobby had mapped the relation well, the ordered pair would have obviously been a function as every x-value will have exactly one y-value assigned the it.
