The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
Answer:
(- 7, 4 )
Step-by-step explanation:
Given the 2 equations
5x + 3y = - 23 → (1)
y = 4 → (2)
Substitute y = 4 directly into (1_
5x + 3(4) = - 23, that is
5x + 12 = - 23 ( subtract 12 from both sides )
5x = - 35 ( divide both sides by 5 )
x = - 7
Solution is (- 7, 4 )
x makes a linear pair with 120 degrees, so is supplementary:
Answer: 60 degrees
Answer:
