8w^2=50 i’m not sure how to find the answer

8w^2=50

= w^2= (50÷8)

= w^2= 6.25

=w = √6.25

w= 2.5

w = 2.5

Step-by-step explanation:

isolate the w^2

8w^2=50

8           8

w^2=50/8

w^2=6.25

√w^2=√6.25    radical signs cancel out the exponent

w=2.5

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

b, i believe, but not sure.
