Answer:

14:

4 × n - 8

15:

8 - 4 × n

Step-by-step explanation:

                                        ~~~~~Hello There~~~~~

1. For number 14, less than is a turn around word, so that means it goes at the end of the expression.

2. 4 times a number means multiplication, so you put that at the start. A number would equal n.

3. Your answer is 4 × n - 8.

1. For number 15, 8 decreased by is not a turn around word, so do not put it at the end.

2. 4 times a number, same thing as number 14 except PUT IT AT THE END.

3. Your answer is 8 - 4 × n

Hope this helped!

Write an equation for a parabola that has a vertex (1, 2) and passes through the point (3, -6).
Alex

Answer:

y= -2x²+4x.

Step-by-step explanation:

the common equation of the parabola is y=ax²+bx+c, where a, b, c - numbers.

1) the coordinates of the vertex are:

x_0=-\frac{b}{2a} \ and \ y_0=\frac{4ac-b^2}{4a}.

2) if according to the condition x₀=1, then b= -2a.

If according to the condition y₀=2, then   2=\frac{4ac-b^2}{4a}=\frac{4ac-4a^2}{4a}=c-a;

it means that c=a+2.

3) if b= -2a; c=a+2 and the point (3;-6) belongs to the given parabola, then it is possible to substitute them into the common equation of the parabola:

-6=3²*a-6a+a+2; ⇔ a= -2.

4) if a= -2, then b=-2a=4, and c=a+2=0.

5) if a=-2, b=4 and c=0, then the required equation of the parabola is:

y= -2x²+4x.

What value of x is in the solution set of 2x - 3 &gt; 11 - 5x<br><br><br> -3<br> 0<br> 2<br> 4
Misha Larkins [42]

<u>Answer:</u>

The answer is D : 4.

<u>Step-by-step explanation:</u>

<em>=2x-3>11-5x</em>

<em>=2x-3+5x>11</em>

<em>=7x-3>11</em>

<em>=7x>11+3</em>

<em>=7x>14</em>

<em>=7x/7>14/7</em>

<em>=x>2</em>

<em />

<em />

<em>By simplifying the problem, you can see that "x" </em><em><u>must</u></em><em> be greater than 2. Therefore, eliminating all other possible answers that are shown, but 4. </em>
