<span>Hello : let  A(4,0)    B(6,-8)
the slope is :   (YB - YA)/(XB -XA)
(-8-0)/(6-4)  = -4
an equation is : y=ax+b     a is a slope</span>

y = -4x +b

 

the line through point  (4,0) : 0 = -4(4)+b<span>
<span>b = 16
the equation is : y =-4x+16</span></span>

BRAINLIEST ASAP!!!!!!!<br><br> why is it useful to factor out the gcf first when factoring
Lelu [443]
By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:
3x(2x + 1) + 10(2x + 1)
These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:

Find the length of AC again
Bingel [31]

Answer:

B

Step-by-step explanation:

side Ac is the opposite of angle B, therefore use the sin ratio to find ac since the hypotenuse is also given

sin B=opposite/hypotenuse

sin 27=ac/15

ac=sin27×15

=6.81

I hope this helps
