The first step would be to subtract 1 from both sides, leaving you with 5x = 10.
Answer: y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
Step-by-step explanation:
the domain of the graph is where on the x axis there is a graph.
here the domain, x, is less than or equal to 6, isnce it goes down on the negative side
the arrow means the line goes on forever, so
x<=6
(x is less than or equal to 6)
Answer:
21 to 3
70 to 10
Step-by-step explanation:
28÷7 = 4
21÷7 = 3
70÷7 = 10
Answer:
y = 3
Step-by-step explanation:
The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.
So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)
Now, we have to get the value of a since the equation id the directrix is y = 4 - a.
Now, the parabola passes through the point (3,5) {Obtained from the graph).
Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1
Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)
