1.
[tex] { \frac{j}{5} } = { \frac{5}{125} } \\ j= 5 \times { \frac{5}{125} } \\ j= { \frac{5}{25} } \\ j={ \frac{1}{5} } [/tex]

Answer is B.

2.
y = -4x - 7

x-intercept where y = 0,
0 = -4x - 7
-4x = 7
x = -7/4

y-intercept where x = 0,
y = -4(0) - 7
y = -7

Answer is C.

3.
[tex] b= { \frac{6}{13y} }+ 12 \\ b - 12 = { \frac{6}{13y} } \\ 13y(b - 12)=6 \\ 13by-156y=6 \\ y(13b-156) = 6 \\ y= { \frac{6}{13b-156} } [/tex]

Answer is none of the above.
