1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is $\frac{1}{2}$ of 12 (hours)
The opposite of $\frac{1}{2}$ is 2
6 (hours) multiplied by 2 (opposite of $\frac{1}{2}$ ) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours

A polygon is translated 3 units to the right and 4 units down, then it’s reflected across the x-axis, and then it’s dilated by a

Marrrta [24]

Answer:

$(x,y)\rightarrow (4x+12,-4y+16)$

Step-by-step explanation:

1 transformation - translation 3 units to the right and 4 units down. This translation has the rule

$(x,y)\rightarrow (x+3,y-4)$

2 transformation - reflection across the x-axis. This reflection has the rule

$(x,y)\rightarrow (x,-y)$

3 transformation - dilation by a factor of 4 with the origin as the center of dilation. This dilation has the rule

$(x,y)\rightarrow (4x,4y)$

Now, the sequence of these three transformation has the rule

$(x,y)\rightarrow\limits^{\text{1st transformation}} (x+3,y-4)\rightarrow\limits^{\text{2nd transformation}}(x+3,-(y-4))\rightarrow\limits^{\text{3rd transformation}} (4(x+3),4(-(y-4)))\\ \\(x,y)\rightarrow (4x+12,-4y+16)$
