Answer:

<h2>"Factor 4 out of the variable terms".</h2>

Step-by-step explanation:

The given equation is

4x^{2} +16x+3=0

Now, according to the problem, Maya is solving by completing the square.

The first step she needs to do is to factor 4 out of the variable terms,

4(x^{2} +4x)+3=0

Then, we move the constant to the other side

4(x^{2} +4x)=-3

Now, we divide the linear term by 2, and find its square power

x^{2} +4x+(\frac{4}{2} )^{2} =-\frac{3}{4} +4\\x^{2} +4x+4=\frac{16-3}{4} \\x^{2} +4x+4=\frac{13}{4}

Then, we factor the perfect square trinomial

(x+2)^{2}=\frac{13}{4}\\

Now, we solve for x

x=\sqrt{\frac{13}{4} } -2

Remember, a square root always has two solutions

x_{1}= +\frac{\sqrt{13} }{2}  -2\\x_{1}= -\frac{\sqrt{13} }{2} -2

Therefore, the first step Maya should take is "Factor 4 out of the variable terms".

Lady_Fox [76]

Answer:

  a) 21%

  b) 45.5%

  c) 26.4%

Step-by-step explanation:

Given the supplied information, a table of probabilities can be constructed. (See the attachment.) The numbers across the bottom reflect the given ratios of customers selecting the different gas types. The numbers in the cells are those bottom numbers multiplied by the percentage that fill the tank (or not). The numbers on the right are the sums of the numbers in each row.

a) The top center cell in the table answers this question. It it the product ...

  p(plus)×p(fill | plus) = 0.35×0.60 = 0.21 = 21%

__

b) The sum on the right answers this question:

  p(fill) = 45.5%

__

c) The ratio of the first column number (12%) to the row sum for Fill (45.5%) answers this question:

  p(regular | fill) = 12%/45.5% ≈ 26.4%

Graph and write solution:<br><br> 2x + 1 = y<br><br> -4x + 6y = -10
PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

2x + 1 = y\\-4x + 6y = -10

Let:

2x + 1 = y\,\,\,eq(1)\\-4x + 6y = -10\,\,\,eq(2)

We can solve this by using Substitution Method.

Putting value of y of eq(1) into eq(2) and finding value of x:

2x + 1 = y\,\,\,eq(1)\\-4x+6(2x+1)=-10\\-4x+12x+6=-10\\8x+6=-10\\8x=-10-6\\8x=-16\\x=-16/8\\x=-2

So, value of x = -2

Now put value of x in eq(1) to find value of y:

2x + 1 = y\\2(-2)+1=y\\-4+1=y\\y=-3

So, value of y = -3

Plotting on graph: x=-2 and y = -3

The graph is shown in figure below

The Solution Set is (-2,-3)
