Graph y = - 1/2r-6 AND GIVE ME THE RIGHT ANSWER.​
Nana76 [90]

Hello!

Are you in algebra?

Here is how to solve and graph.

First, look for the slope and y-intercept of your equation.

y = - 1/2r-6

The y intercept is, -6

The slope is -1/2

the variable r, is another way to represent x, as it is just a variable.

now that you have all that information, plot -6 on the graph, -6 should be on the y- axis.

from that point, move down one space and move right two space. complete this step multiple times.

Now please look at the photo, and Here's what the graph should look like.

Factor the GCF: 12a^3b + 8a^2b^2 — 20 ab^3
geniusboy [140]

Answer:

GCF is 4ab

And the expression will be: 4ab ( 3a^2+2ab-5b^2)

Step-by-step explanation:

Factor the GCF :

12a^3b + 8a^2b^2-20 ab^3

We need to find the common terms that are common in each of the term given above

12,8 and 2 are all divisible by 4

a is common in all terms and b is also common in all terms,

So, GCF is 4ab

Taking 4ab common

12a^3b + 8a^2b^2-20 ab^3=4ab ( 3a^2+2ab-5b^2)

grigory [225]
D'(p) = -8p + 160 

<span>-8p + 160 = 0 </span>

<span>-8p = -160 </span>

<span>p = 20 </span>

<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>

<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>

I think this is right, i tried.
