First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them
12x^8/3x^3= 4x^8-3=4x^5
20^2x=20^x*20^x
m^5*m^-7=m^5-7=m^-2
Answer:

.
Step-by-step explanation:


Answer:
C
Step-by-step explanation:
y = 2x -5
y= -3x + 1
Here both the equations are in y = mx + b
where m is the slope and b is the y intercept
y =2x -5, the slope = 2 and b intercept = -5
y= -3x + 1, the slope = -3 and b intercept = +1
Both the equations have different slope. So there should be a single solution
Yes, the system of equations have a solution
