Answer:
A
Step-by-step explanation:
(25+15)-5=40-5=35
25+(15-5)=25+10=35
Minus 1 on both sides
Divide by 3 on both sides
C 5 > 7/3
+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have:
5</span>=a(1-3)<span>²+2 , so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2
And by checking we have the point (5;5) is on the parabola
