Answer:

x = -7

Solution:

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

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

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

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

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

drek231 [11]

Width of the actual barrier = 1.2 miles

Width of the barrier in the blueprint = 2 inches

2 inch dimension of blueprint = 1.2 miles of original

So, 1 inch dimension of blueprint = 1.2/2 = 0.6 miles.

Since the length of the barrier in the blueprint = 9 inches,

length of the actual barrier = 9(0.6) = 5.4 miles.

XY is a translation of XY.
seropon [69]

Given:

The graph of a translation. X'Y' is a translation of XY.

To find:

The rule of the translation.

Solution:

Let the rule of the translation be

(x,y)\to (x+a,y+b)            ...(i)

So, we need to find the value of a and b.

From the given graph, it is clear that X(-4,-9) and X'(-1,0).

Using (i), the image of X(-4,-9) is

X(-4,-9)\to X'(-4+a,-9+b)

We have, X'(-1,0). So,

X'(-4+a,-9+b)=X'(-1,0)

On comparing both sides, we get

-4+a=-1

a=-1+4

a=3

And,

-9+b=0

b=9

So, the missing values in the rule of the translation are 3 and 9 respectively.

Therefore, the rule of translation is (x,y)\to (x+3,y+9).
