Vertex form uses the following formula:

y = a(x-h)^2 + k

Identify the values of h and k in your function:

(x+5)^2 - 28
h = -5, k = -28

The vertex is found with the following point:

(h,k)
\text{Vertex: (-5, -28)}

The vertex will be found at (-5, -28).

Officials begin to release water from a full man-made lake at a rate that would empty the lake in 14 weeks, but a river that can
Margarita [4]

Answer:\frac{140}{3} weeks

Step-by-step explanation:

Given

It takes 14 weeks to empty a lake

also it takes 20 weeks for a river to fill the lake

Part of lake empty in 1 week =\frac{1}{14}

Part of lake filled in 1 week is =\frac{1}{20}

And if both works simultaneously then

\frac{1}{14}-\frac{1}{20}=\frac{10-7}{140}

=\frac{3}{140}

therefore it takes \frac{140}{3} weeks to fill it

Solve for x. Write both solution, separated by a comma. 4x^2-x-3=0.
Step2247 [10]

Answer:

x = -3/4, 1

Step-by-step explanation:

Factor left side of the equation.

(4x + 3)(x - 1) = 0

Set factors equal to 0.

4x + 3 = 0

4x = -3

x = -3/4

x - 1 = 0

x = 1
