Answer:
y = 3(x+1)^2 - 4
Step-by-step explanation:The general form of the equation of a quadratic function whose vertex is (h,k) and whose leading coefficient is a is:
y - k = a(x-h)^2, or
y = a(x-h)^2 - k
Substituting the coefficients of the vertex (-1, -4), we get:
y = a(x + 1)^2 - 4
Substituting the coordinates of the given point, (1,8), we get:
8 = a(1+1)^2 - 4, which simplifies to:
8 = a(2)^2 - 4, or
8 = 4a - 4. Then 4a = 12, and a = 3.
Thus, the desired equation is y = 3(x+1)^2 - 4 (answer j).
You would use the distributive property with the negative. So the second x becomes negative, but since the 7 is already negative it becomes positive. Think of it as if you put the two dashes together you can make a plus sign.

Answer:
Simple:
(-2.5,-1) goes 2.5 units left and 1 units down
(0.5,2) goes half a unit right and 2 units up
Step-by-step explanation:
Hi i'd be glad to help you with this equation.
basically all we have to do is find (65%) of 455*.
65% of 455* = 295.75
Next.
455 + 295.75 = 750.75
So, to check my work I have 750.75 miles in total.
I have already driven 455 miles of 750.75 miles.
Using subtraction we subtract our distance from our total.
750.75 - 455 = 295.75
So, in total your answer to this problem is (295.75)
Hope this helps.
Have a great day!
