Variables that are the same are added so 4a and 2a are added making it 6a. Now you have 13+6a=3a+1. Now you have to move things. Move the 3a to the other side making it a negative. So now you have 13+6a-3a=1. You now have 13+3a=1. So move the 13 to the other side. 3a=13-1. Which makes 3a=12. All you have to do now is 12 divided by 3. So a=4

The tallest building in Franklin is two-thirds the
drek231 [11]

Answer:

The height of tallest building in Franklin is \[\frac{431}{8}\] feet or 53\[\frac{7}{8}\] feet.

Step-by-step explanation:

Given:

The height of tallest building in Mayville is 80\[\frac{13}{16}\] feet or \[\frac{1293}{16}\] feet. (Simplifying the fraction)

And the tallest building in Franklin is 2/3rd of the tallest building in Mayville.

So, multiply the height of Mayville with \[\frac{2}{3}\] to get the height of tallest building in Franklin.

Thus, the height of tallest building in Franklin will be,

h=\[\frac{1293}{16}\]\times\frac{2}{3}\\h=\frac{431}{8}\\h=53\frac{7}{8}

The height of tallest building in Franklin is \[\frac{431}{8}\] feet or 53\[\frac{7}{8}\] feet.

.........help...............
stealth61 [152]

Answer:

1. X axis, 8, 3

2. Y axis, 4,-9

Step-by-step explanation:

The rule of reflections that the place opposite of the axis is negative so:

The rule for x-axis reflection is (x,-y)

The rule for y-axis is (-x,y)

For the first one, x has remained the same, so that means it’s a x-axis reflection.

So change -3 to 3

Same for the next one.

-9 is not changed so that means it’s a y-axis reflection.

And the point is 4,-9
