Answer:
A. -6
Step-by-step explanation:
f(-7)=2(-7)+8
=(-14)+8
=-6
F(x) = x² - 4x -5, factored is simply f(x) = (x - 5)(x + 1).
if you zero out f(x), namely 0=(x-5)(x+1), that simply gives you the zeros of 5 and -1.
now, from ----- -1------0---------------------------------5, notice from -1 to 5, there are 6 units, and half of 6 is 3, so, the half-way is 3 units away from either zero.
so we can get to the half-way point by -1 + 3, or 2, x = 2, that's where the vertex is at, but you already knew that, and of course the y-coordinate is at f(2) = (2)² - 4(2) - 5, which is -9, so the vertex is indeed at (2, -9).
now to draw it, well, surely you can, simply use the zeros location, -1 and 5, and draw a bowl between them, with the bottom of the bowl at 2, -9.
Answer:
y=3/5
Step-by-step explanation:
9y+6=9+2y+2y
9y+6=9+4y
9y-4y=9-6
5y=3y=3/5
Answer:
So 30:1/2
So you can times both sides by 2
60:1
Now you can multiply 60 by 4 (The total times the time you need)
Your answer is 240
The baker can make 240 gingerbread cookies in 4 hours
