The y-intercept of the equation is the value of the variable y or in this case, f(x), when x is equated to zero. Out of all the choices presented in this item, if x is equated to zero, the first two terms will be equal to zero, leaving the third term only for the numerical value of f(x).
From the choices presented, the answer would be f(x) = -x2 + 2x + 4. Thus, the answer is the third choice, C.
The correct answer would be 3.
1+(-1)-(-3)
1+(-1)=0
0-(-3)
0+3= 3
I believe the answer is A "If a triangle is equilateral, then it has three congruent angles". Hope this helps!
Answer:Part A: 13
Step-by-step explanation: look at the graph
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
