so.. what is the coefficient "a"?
well
now, we know, another point on the graph, besides the vertex, we know a y-intercept, that is, 0, -30, that simply means when x = 0, y = -30
now, getting the x-intercepts, is just the zeros, or solution to the quadratic
notice, "y" is 0 on both cases, because, is an x-intercept, or a zero, and when the graph touches the x-axis, "y" is zero
Answer:
<h2>4 mph</h2>
Step-by-step explanation:
To find the rate of mph we will multiply. Keep in mind that:
<h3>1 hour = 60 minutes</h3>
Because we have a rate in 10 minutes, this is easy. We just multiply 2/3 by 6 to get our answer.
2/3 x 6 = 4
Mario walks at a rate of 4 miles per hour.
