Answer:

x = 3

Step-by-step explanation:

The goal of solving this equation is finding the value of the variable, "x". To do that, we need to get x alone on one side of the equation.

Our first step is to Combine Like Terms.

(7+5)(x-2)=12\\\\12(x-2)=12

Next, Divide 12 from both sides of the equation.

12(x-2)=12\\\\\frac{12(x-2)}{12}=\frac{12}{12}\\\\x-2=1

Finally, Add 2 to both sides of the equation.

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

So, x is equal to 3.

Answer: x=3

Step-by-step explanation:

7+5(x-2)=12

Open bracket

7+5x-10=12

Collect like terms

5x-3=12

5x=12+3

5x=15

X=15/5

X=3

Find the mode: 16,12,10,15,7,916
Airida [17]

The mode is the value from a given set of data that occurs most often. It is the data with the highest frequency.

Given:

16,12,10,15,7,9,16

Form the above data given;

Rearranging for easy identification, we have;

7,9,10,12,15,16,16

\begin{gathered} 7\text{ appears once} \\ 9\text{ appears once} \\ 10\text{ appears once} \\ 12\text{ appears once} \\ 15\text{ appears once} \\ 16\text{ appears twice} \end{gathered}

From the above, we can deduce that the mode is 16 because it appears the most often. It appears twice.

Therefore, the mode is 16.

7. log(x+3)(2x + 3)+log(x+3)(x +5)= 2
OverLord2011 [107]

log(x+3)(2x+3)+log( x+3)( x+5) =2

logx(2x+3)+3(2x+3 )+log x(x+5)+3(x+5)

log {2x}^{2}  + 3x + 6x + 9 + logx {}^{2}  + 5x + 3x + 15

A parabola can be drawn given a focus of (-11, -2) and a directrix of x= -3
fgiga [73]

Check the picture below, so the parabola looks more or less like that.

now, the vertex is half-way between the focus point and the directrix, so that puts it where you see it in the picture, and the horizontal parabola is opening to the left-hand-side, meaning that the distance "P" is negative.

\textit{horizontal parabola vertex form with focus point distance} \\\\ 4p(x- h)=(y- k)^2 \qquad \begin{cases} \stackrel{vertex}{(h,k)}\qquad \stackrel{focus~point}{(h+p,k)}\qquad \stackrel{directrix}{x=h-p}\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix}\\\\ \stackrel{"p"~is~negative}{op ens~\supset}\qquad \stackrel{"p"~is~positive}{op ens~\subset} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}

\begin{cases} h=-7\\ k=-2\\ p=-4 \end{cases}\implies 4(-4)[x-(-7)]~~ = ~~[y-(-2)]^2 \\\\\\ -16(x+7)=(y+2)^2\implies x+7=-\cfrac{(y+2)^2}{16}\implies x=-\cfrac{1}{16}(y+2)^2-7
