Step-by-step explanation:

<u>Payment is</u>

  • 7.20 for every 4/5

<u>Divide both by 4/5 to find payment per hour</u>

  • 7.20 ÷ 4/5 ⇔ 4/5 ÷ 4/5
  • 7.20 ÷ 0.8 ⇔ 1
  • 9.00 ⇔ 1

URGENT, will reward brainliest. Determine the equation of the graph and select the correct answer below.
PilotLPTM [1.2K]

In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:

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

  • a is a constant which helps to determine whether the parabola opens up or down. If a < 0, then the parabola opens downward and if a > 0, the parabola opens upwards
  • (h, k) is the vertex of the parabola

By looking at the graph, we can first see that the graph opens downwards, meaning that a < 0. Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.


The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:

y = -(x + 1)^2 + 3


The answer is a, -(x + 1)^2 + 3.

Simplify and answer the boxes.
s2008m [1.1K]

Answer:

\huge\boxed{\dfrac{x^2+9^2}{x-3y}+\dfrac{6xy}{3y-x}=x-3y}

Step-by-step explanation:

Domain:

x-3y\neq0\Rightarrow x\neq3y

\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{3y-x}=\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{-(x-3y)}\\\\=\dfrac{x^2+9y^2}{x-3y}-\dfrac{6xy}{x-3y}=\dfrac{x^2+9y^2-6xy}{x-3y}\\\\=\dfrac{x^2-2(x)(3y)+(3y)^2}{3y-x}=\dfrac{(x-3y)^2}{3y-x}\\\\=\dfrac{\bigg[-1(3y-x)\bigg]^2}{3y-x}=\dfrac{(-1)^2(3y-x)^2}{3y-x}\\\\=\dfrac{1(x-3y)(x-3y)}{x-3y}=x-3y

Used:

The distributive property: a(b + c) = ab + ac

(a - b)² = a² - 2ab + b²
