<span>12x-4y=-8
y=3x+2 can sub for y in the first equation: 12x - 4(3x+2) = -8
Then 12x - 12x - 8 = - 8
This is true for all x, so there are infinitely many sol'ns.

Answer:
y^-1 = (x + 4)/5
Step-by-step explanation:
To find the inverse equation of the function y=5x - 4, first we need to switch the x and y:
→ y = 5x - 4
→ x = 5y - 4
Now, solving for 'y':
→ x = 5y - 4
→ x + 4 = 5y
→ y = (x + 4)/5
therefore, the inverse equation is: y^-1 = (x + 4)/5
Answer:
For the first question(B)
x=-2
x=5
For part C, the question is not clear
For the last question, the approximated value is -5/4
Answer:
Step-by-step explanation:
A root can be converted to a power by taking the base of the root (in this case 4) and making it 1 over that number, so in this case 
If it were the fifth root you would make it to the 1 over 5 power.
