19/20

Step-by-step explanation:

You have 3/4 + 1/5 which you can't add because you don't have like denominatiors so you multipliy 3/4 by 5 and 1/5 by 4 which gives you         15/20 + 4/20 = 19/20

Ab and bc form a right angle at point B. if a= (-3,-1) and B= (4,4) what is the equation of BC?
Vesnalui [34]

Answer:

Option C -7x-5y=-48

Step-by-step explanation:

step 1

Find the slope of AB

we have

A(-3,-1) and B(4,4)

The slope m is equal to

m=(4+1)/(4+3)

m=5/7

step 2

Find the slope of BC

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

so

m1*m2=-1

we have

m1=5/7

substitute

5/7*m2=-1

m2=-7/5

step 3

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have

m=-7/5

B(4,4)

substitute

y-4=-(7/5)(x-4)

Multiply by 5 both sides

5y-20=-7x+28

7x+5y=28+20

7x+5y=48

Multiply by -1 both sides

-7x-5y=-48
