The equation is 329-34 and then you check if you sibtract right by adding 34 by the nimber you got when you subtract if it gives you 329 you are right

329 - 34! This one is really easy. You always subtract the number you have, here being 34, by the number you need, here being 329.

What are the intercepts if the graphed functions

KonstantinChe [14]

The intercepts represent the points where the graph touches the axis the given. With that said, your y intercept is (0, -3) and the x intercept is (-1,0).

Write a function rule that relates r and t.

Svetlanka [38]

Answer: $t=-\frac{1}{2}r- 1$

Step-by-step explanation:

For a lineal equation $t=mr+n$

For r=0 and t=-1

$-1=m(0)+n\\n=-1$

For r=-2 and t=0

$0=m(-2)-1\\m(-2)=1\\m=-\frac{1}{2}$

Them $t=-\frac{1}{2}r- 1$

???? The output for 6 is 1????

What value of m does the graph y = 18x2 + mx + 2 have exactly one x-intercept?

Vlada [557]

To get the graph to have one x-intercept, we must find the m value where the discriminant of the equation will equal 0.

The discriminant for a graph with one x-intercept is found with the following formula:

$b^2 - 4ac = 0$

Plug in the values of the equation into this formula:

$\text{a = 18, b = m, c = 2}$
$m^2 - 4(18)(2) = 0$
$m^2 - 144 = 0$

Add 144 to both sides:

$m^2 = 144$

Square root both sides to get m by itself:

$\sqrt{144} = \pm 12$
$m = 12, \ m = -12$

In order for the graph to have one x-intercept, m must equal -12 or 12.
