Answer:
24 is what I got
Just find the are of each shape and add the answers together to get the total area of the figure
Answer:
a) y=-1
Step-by-step explanation:
Graph is intersecting y-axis at (0,-1)
So equation of the graph is y = - 1
You would just do 1÷5 so it would equal 20 or 20%.
Y = a(x-0)^2 + 3
y = ax^2 + 3
plug in the point (-4,-45):-
-45 = (-4)^2 a + 3
-45 = 16a + 3
a = -48/16 = -3
answer is -3x^2 + 3
