Answer:
This is a linear function.
Step-by-step explanation:
x is going up by 1 each time
y is going up by 10 each time
it is constant so it is a straight line
It’s b because if you do the math you can see that
550-500 is not 500 it’s 50
What do you need hepl on becasue i dont know
Answer:
(4, 5 )
Step-by-step explanation:
x + y = 9 → (1)
x - y = - 1 → (2)
adding the 2 equations term by term will eliminate y
2x + 0 = 8
2x = 8 ( divide both sides by 2 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
4 + y = 9 ( subtract 4 from both sides )
y = 5
solution is (4, 5 )
