Answer:
Step-by-step explanation:
If y varies directly as x, then we can write the relation
where k is the constant of proportionality.
We substitute y=-319 when x=29.
This implies that:
The variation equation now becomes
Answer:
x > -1
Step-by-step explanation:
Isolate the variable, x. Treat the > sign like an equal sign, what you do to one side, you do to the other.
Subtract 5 from both sides:
x + 5 (-5) > 4 (-5)
x > 4 - 5
x > -1
x > -1 is your answer.

Answer:
The third (y=2x–5)
Step-by-step explanation:
y=2x–5
if we substitute then:
3=2(4)–5
3=8–5
Answer:
