It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,
aivan3 [116]

Answer:

k=\dfrac{5}{4}

Step-by-step explanation:

Given that,

y varies directly as x. It means,

y = kx

Where

k is the constant of variation

or

k=\dfrac{y}{x}\\\\k=\dfrac{5}{4}

So, the constant of variation is \dfrac{5}{4}.

Use the graph to estimate the solution to the system of equations shown.
Finger [1]
<h3>Answer:  D. x= -5 1/2, y= -3 1/4</h3>

==============================================================

Explanation:

The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate

Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.
