Y = 3x + 9
3x = y - 9
x = 1/3 y - 3
Inverse is y = 1/3x - 3
Answer:
No, because 234 / 36 is 6.5 which is what Chad makes hourly. 288 / 40 is 7.2 which is what Geo makes hourly so it is not proportional.
Step-by-step explanation:
Answer:
x
Step-by-step explanation:
It is rational and equal to 0. square root of 28 simplifies to 2 root 7, because you can take out the 4 and leave the 7 under the radical. because sq rt of 28 is 2 root 7, it's the same as the first term so it equals 0
Answer:
Given system of equations:

To solve by substitution, equate the equations and solve for x:

Therefore, the x-values of the solution are
and
.
To find the y-values of the solution, substitute the found values of x into the functions:




Therefore, the solutions to the given system of equations are:
and
