Hello there!

Solve for x using the distributive property:

6(2x+1)=18

12x+6=18

12x=12

x=1

Answer:

x=1 if you can give brainliest that would be great

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(2x+1)=18

(6)(2x)+(6)(1)=18(Distribute)

12x+6=18

Step 2: Subtract 6 from both sides.

12x+6−6=18−6

12x=12

Step 3: Divide both sides by 12.

12x/12=12/12

Complete the point-slope equation of the line through (2,3 and (7,4). Use exact numbers.

uysha [10]

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$

Step-by-step explanation:

The form of the point-slope equation is $y-y_{1}=m(x-x_{1})$ , where

m is the lope of the line
$(x_{1},y_{1})$ is a point lies on the line

The slope of a line $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where

$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points on the line

∵ The line through (2 , 3) and (7 , 4)

∴ $x_{1}$ = 2 and $x_{2}$ = 7

∴ $y_{1}$ = 3 and $y_{2}$ = 4

- Substitute these value in the rule of the slope

∵ $m=\frac{4-3}{7-2}=\frac{1}{5}$

∴ the slope of the line is $m=\frac{1}{5}$

Let us substitute the value of the slope and the coordinates of point $(x_{1},y_{1})$ in the form of the equation

∵ $y-y_{1}=m(x-x_{1})$

∵ $x_{1}$ = 2 and $y_{1}$ = 3

∵ $m=\frac{1}{5}$

∴ $y-3=\frac{1}{5}(x-2)$

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$

22. Mona is in her garden jumping on stones (as shown below).

iris [78.8K]

$\large\green{\sf\boxed{Given:-}}$

Mona starts from 68th stone

She jumps 23 stones ahead 

Then she jumps 28 stones back

$\large\red{\sf\boxed{To \:find:-}}$

Her final position=?

$\large{|\underline{\mathtt{\red{S}\blue{o}\orange{l}\pink{u}\blue{t}\purple{i}\green{o}\red{n}\blue{:}\orange{-}}}}$

Add 23 in 68 [Given]

$\begin{gathered}\\ \sf\longmapsto 68+23=91\end{gathered}$

Subtract 28 from 91

$\begin{gathered}\\ \sf\longmapsto 91-28=Her\:final\:position\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto =63\end{gathered}$

To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

$\begin{gathered}\\ \sf\longmapsto 68-63=5\end{gathered}$

So, Mona will be 5 stones behind from the starting stone.

☯️Hence, Option C is correct
