I don’t get this one but the question was something about finding the equation.

Answer:

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

Step-by-step explanation:

The vertex form of the equation for a parabola is ...

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

where the vertex is (h, k) and the value 'a' is a vertical scale factor.

The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.

Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...

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

2x-4/5=4<br> plsss answer quick

nikdorinn [45]

Answer:

<h2>x = 12</h2>

Step-by-step explanation:

$\frac{2x - 4}{5} =4$

First of all multiply through by 5 to eliminate the fraction

That's

$5 \times \frac{2x - 4}{5} = 4 \times 5 \\ 2x - 4 = 20$

Next using the addition property add 4 to both sides of the equation

We have

$2x - 4 + 4 = 20 + 4 \\ 2x = 24$

<u>Divide both sides by 2</u>

$\frac{2x}{2} = \frac{24}{2}$

We have the final answer as

<h3>x = 12</h3>

Hope this helps you

Compute: 5 ∙ (2 + 3i)

dimulka [17.4K]

Answer:

It will be equal to 40

Step-by-step explanation:

We have to compute $5\times (2+3!)$

Let first find 3 !

For this we have to use factorial concept

So 3! will be equal to 3! = 3×2×1 = 6

Now According to 6+2 = 8

And now after solving bracket we have to multiply with 5

So 5×8 = 40

So after computation $5\times (2+3!)=40$

So the final answer will be 40
