Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
What is 19 and 20 you didn’t put anything
Answer:
the answer is c as you see
Step-by-step explanation:
X - y = 5,
x = 5 + y
substitute (x = 5 + y) into the first equation,
5 + y + 2y = -1
3y = -6
y = -2,
substitute y = -2 into (x - y = 5),
x + 2 = 5
x = 3
Hence, x = 3, y = -2
Answer:
Hence , (a,0) is a zeros of a function
