Answer:

The roots are: (12 + \sqrt{224})/2 and (12 - \sqrt{224})/2

Step-by-step explanation:

We can solve this with the quadratic formula! Plugging it all in, we get (12 +/- \sqrt{144+80})/2 This simplifies to  (12 +/- \sqrt{224})/2. So the roots of our equation are (12 + \sqrt{224})/2 and (12 - \sqrt{224})/2.

Write an ordered pair for each point graphed below.
Viefleur [7K]

Answer:

\boxed{(-1,4)}

Step-by-step explanation:

The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.

Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to (0,0).

So, you can count backwards once from the origin to get your x-value ⇒ -1 and count up upwards four times from x=-1 to get your y-value ⇒ 4.

Finally, place these in a coordinate point (x,y) ⇒ \boxed{(-1,4)}.

<span>so 60 + 55 = 115 </span>
<span>60 + 65 = 125 </span>

F(x)=-5x+2 and g(x)=1/2x+4 find f(g(12))
skad [1K]

Answer:

- 48

Step-by-step explanation:

If you want to learn more about this concept, it's called composition of functions.

First, you plug in g(x) as if it were x into f(x).

f(g(x))= -5 (1/2x + 4) + 2

= -5/2x - 20 + 2

= -5/2x - 18

Then, plug in the value given, as x.

= -5/2 (12) - 18

= -30 - 18

= - 48

I hope this helped!
