If y = 6 when x = 8, then value of "x" when y = 9 is equal to 12
<u>Solution:</u>
Given that , In a certain function, y varies directly with x
And x = 8 when y = 6,
We have to find what will be the value of x when y = 9
Now, from the given information,

where c is the proportionality constant

Hence, x value is 12 when y value is 9
Answer:
its Aor the first option because it has repeated x values making it not a function.
Answer:
4(3x+2), 4(3x)+4(2), 12x+8
Step-by-step explanation:
The answer is x=-80.
First subtract 4 from both sides.
-6=
+4
-6-4=
+4-4
-10=
Multiply 8 on both sides to isolate x.
-10·8=
-80=x
