Y= 16x2 - 8x+1 does not intersect the c axis. It only peaks at it. The parabola does not go over it.

The vertex of the parabola occurs at (1/4, 0) or (0.25, 0). Since the coefficient of x^2 is a positive number, then it the parabola opens upward. The vertex is the minimum point on the graph, which happens to occur along the x-axis at (1/4, 0) as the only x-intercept.

Therefore, the graph intersects the x-axis only once, at the vertex.

Hey there!

In order for you to solve for this equation, you need to multiply. That’s what the “•” is or means!

32 • 35 = ?

None of the above, because 32 times 35 equals 1,120

Good luck on your assignment and enjoy your day!

A pair of equations is shown below:

Archy [21]

Slope Intercept Form - y = mx + b

First you need the slope or m which in the first equation is 6 and in the second is 5

Next the y-intercept or b which in the first equation is -4 and in the second is -3

Here is an image of both equation plotted on a graph where the first equation is purple and the second is green

Hope this helps, if you need anything else i will edit it in :)

edit: The to lines intercept at the point (1,2)

Sorry, i wasn't completely sure what you needed i haven't done this in a while. If you still need more, I'll try to help.
