loris [4]

Answer:

(x+4)(x+25)

Step-by-step explanation:

x*x=x^2

x*20=20x

4*x=4x

4*25=100

x^2+20x+4x+100

put the commons together and you will get

x^2+29x+100

Answer:

y = -1/5x

Step-by-step explanation:

Using the 'y=mx+c' form for the equation:

Find the slope (m):

Since the product of both slopes should be -1 (if they are perpendicular),

s₁s₂  = -1

5*s₂ = -1

s₂ = -1/5x

Hence, the slope (m) is -1/5x.

Substituting the slope value into 'y=mx+c':

y = -1/5x+c -----(1)

Substituting the point (-5,1) into the equation (1):

1 = -1/5 * (-5) + c

1 = 1 + c

c = 0

Substitiuting 'c=0' into 'y = -1/5x+c':

y = -1/5x

Hence,

y = -1/5x
