What does the value of x have to be so that
(x,-7) and (-1,4) have a slope of 11/4 between them?

x=-5

Step-by-step explanation:

slope=m=11/4

(x, - 7) x1 =x, y1 =-7

(-1,4) x2=-1, y2 =4

m=(y2-y1) /(x2-x1)

m=(4-(-7))/(-1-x)

11/4=(4+7)/(-1-x)

11/4=11/(-1-x)

then 4=-1-x,

-x=4+1

-x=5

x=-5

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
