Answer:

√116 (or 10.77)

Step-by-step explanation:

(refer to attached )

in this case the points given are (-4,-3) and (-8,7)

hence x1 = -4, y1 = -3, x2 = -8, y2 = 7

D = √[ (x2-x1)² + (y2-y1)² ]

= √[ ( -8 - (-4) )² + ( 7 - (-3) )² ]

= √[ ( -8 +4 )² + ( 7 + 3 )² ]

= √[ ( -4 )² + ( 10 )² ]

= √[ ( 16 ) + ( 100 ) ]

= √116

= 10.77

The answer has to be in y-intercept form. Which is y=mx+b and b can also be neg. y=mx-b. The m is your slope and b is your y-intercept. So A’s slope counting from 3 on the y axis to 1 on the x-axis which is down 2 over 1 so it will be -2/1. And your y intercept is 3. The equation is y=-2x+3. For B its the same thing but no graph. Remember that slope is RISE over RUN. So since the number is on the bottom of the line the rise is 4 and the run is 1. So in this case 10 is your y-intercept. Which means you equation is y=4x+10.

Suppose you can factor x^2 + bx + c as (x + p)(x + q). If c > 0, what could be possible values of p and q?

ad-work [718]

p could be 5 and q could be 8 this is just my guess but i think its right
