We first want to find the equations of the lines. The general equation of a line is: (y-y₁)=m(x-x₁) where (x₁,y₁) are the coordinates of a point on the line and...

a).  x-4=13

13+4=17

x=17

b). 7y=35

35/7=5

y=5

c). 3w-9=27

3w=27+9

3w=36

w=36/3

w=12

R = 5^0.5

b = 26.57 degrees

To find the reciprocal of any graph, first consider the key points, in this case: (0,1), (90,0), (180,-1), (270,0) and (360,1). Since we are finding the reciprocal in the y-axis, we can find the reciproca...

log₈5=b

using the base change rule

log₈5=log₄5/log₄8

log₄8 can be solved:...
