2x-y=7
y=2x+3
Substitute (2x+3) in for y in the first equation
2x-(2x+3)=7
2x-2x-3=7
-3=7
Becuase -3 does not equal 7 the answer is no solution
Answer: I think it is 8 meters because 83 cm in meters is 0.83 meters :)
Step-by-step explanation:
For any polynomial equation, The Fundamental Theorem of Algebra tells you that the highest degree present will tell you how many complex roots the equation has. There are only two terms, "
" and "3". The term has a degree of 5, its exponent. The 3 term has a degree of zero, because you could write it as 
using the zero exponent rule.
The degrees present are 5 and 0. Choose the highest one, 5. So, the answer here is D.
You use (y2-y1)/(x2-x1) so if you have two points (ex: (1,2) and (2,4)), plug in those number into the formula
(4-2)/(2-1) = 2/1 = 2 so the slope (or instantaneous rate of change) is 2 for those two points<span />
