Solve for N. <br> 2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]

jonny [76]

Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Step-by-step explanation:

We need to solve the equation $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ and find value of n.

Solving:

$2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$

Multiplying the terms inside the bracket

$2[7-6+6n]+3n=-20+4[6n+6-3n]$

Simplifying:

$2[1+6n]+3n=-20+4[6n-3n+6]$

$2[1+6n]+3n=-20+4[3n+6]$

$2+12n+3n=-20+12n+24$

$2+15n=12n+4$

Adding -12n and -2 on both sides

$15n-12n=4-2$

$3n=2$

$n=\frac{2}{3}$

So, Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Given the triangle ABC with points:

mixer [17]

Rotating and translating the triangle are illustrations of transformations

The ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)

<h3>How to transform the triangle</h3>

The coordinates of the pre-image of the triangle are:

A = (1, 3)

B = (-2, 2)

C = (4, 0)

When the triangle is rotated 180 degrees, the rule of transformation is:

(x,y)→(−x,−y)

So, we have:

A' = (-1, -3)

B' = (2, -2)

C' = (-4, 0)

When the triangle is translated 5 units down, the rule is:

(x,y)→(x,y-5)

So, we have:

A' = (-1, -8)

B' = (2, -7)

C' = (-4, -5)

Hence, the ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)
