Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1
Answer:
Step-by-step explanation:
5x - 4 - (4x + 1)
5x - 4 - 4x - 1
x - 5
Answer:

Step-by-step explanation:
We have a separable equation, first let's rewrite the equation as:

But:

So:

Multiplying both sides by dx and dividing both sides by 3a+y:

Integrating both sides:

Evaluating the integrals:

Where C1 is an arbitrary constant.
Solving for y:


So:

Finally, let's evaluate the initial condition in order to find C1:

Solving for C1:

Therefore:
