D is the only x-intercept out of the options listed below.



In order to find an x-intercept, you need a value that will cause the y-value to equal 0, since this is where x-intercepts exist.



Automatically, A and B do not work since the y-values in the ordered pairs do not equal 0. By definition they are not x-intercepts. Next we can try the x-values in the equation to see which gives us a 0 y-value.



C


f(x) = (x + 6)(x - 3)


f(6) = (6 + 6)(6 - 3)


f(6) = (12)(3)


f(6) = 36



Since this does not equal 0, it is not an x-intercept.



D


f(x) = (x + 6)(x - 3)


f(-6) = (-6 + 6)(-6 - 3)


f(-6) = (0)(-9)


f(-6) = 0



This shows us that D yields a 0 value for y and is thus a x-intercept.

A car moves with an average speed of 45 miles/hour. How long does the car take to travel 90 miles? A. 2 minutes B. 2 hours C. 45
svlad2 [7]

We know that distance = rate(time). We need to solve for time here.

d = rt\\90 = 45t\\t = \frac{90}{45}\\t = 2


The car took 2 hours to travel 90 miles at a speed of 45 mi/hr
