(3x^2-2x+4)+(5x^2+6x-8) - Combine like terms
8x^2+4x-4
(f+g)(x)=8x^2+4x-4
Answer:
-385
Step-by-step explanation:
If -5 = x, then f(x) = -15-365-5 which is -385.
The equation of hyperbola can vary much from simple to complex equation. Since the information given from this question is not many, the equation probably was the simple one.
Assuming that the hyperbola formula is y= x^2 +b, then the value of b where x=-2 and y=-3 would be:
y= x^2 +b
-3= (-2)^2 +b
-3= 4+b
b=-3 -4= -7
The equation would be: y= x^2 -7
he know that the angle of each corner is 90º because the two lenghths and the two wides are parallel this means that the figure is a rectangle. so the solution isnumeral A)
