What is an equation of a line perpendicular to the line with equation
y = 1 - 3x

a.y=-3x + 5 b. y=3x + 5
c.y=-1/3x + 5 d. y=1/3x + 5

To solve the linear system below, which substitution of unkowns is proper ?
x + 4y= -6
5x - 3y = -16

a. substitute -4y-6 for x in the first equation

b. substitute 4y - 6 for x in the second equation

c.substitute 3y + 16 for x in the second equation

d. -4y - 6 for x in the second equation

What is the solution of the equation
3(1/4x - 1/4)= 4x - 1 ?

Using the formula for interest, I = Prt, solve for r.

please solve these problems clearly so I can follow and understand them, thank you .
