Two rovers are exploring a planet. The system of equations below shows each rover's elevation y at time x. Without graphing these equations, what conclusion can you make about the system of equations? Use pencil and paper. Rover 1. y = 1.2x - 6
Rover 2. y = 8.4x - 42

A. The system has exactly one solution.
B. The system has infinitely many solutions.
C. The system has no solution.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
