Answer: y = 4x + 20
Step-by-step explanation:
4x - y = -20
=> -y = -4x - 20
=> y = 4x + 20
Answer:
3
Step-by-step explanation:
Pepper Jackie has 12 picks, 1 out of every 4 pick is orange and the rest are green.
So there could be three groups of 4 each and in each group there is 1 orange.
There are 3 groups of 4 each that makes 12 ()
Now, in each group there is 1 orange, so in three groups there will be
orange.
1 for each group.
Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
