0, scalene triangle. none of the sides are the same length
We can use substitution to solve for x then substitute the x value back into the original equation to solve for y...
5x + 2y = 7
y = x + 1
Since y = x + 1, we can substitute x + 1 for y in the first equation
5x + 2(x+1) = 7
5x + 2x + 2 = 7
7x + 2 = 7
7x = 5
x = 5/7
Now substitute 5/7 for x in either of the original equations
y = x + 1
y = 5/7 + 1
y = 1 5/7
Solution set is (5/7, 1 5/7)
Answer:
C) B>A
Step-by-step explanation:
if it doesn't make sense think of it like the number in between A and B is .5. You can visibly see that A is less than or below .5 and B is above or greater than .5, so B is greater than A.
