Answer:

1/6a-1/6, a=1

Step-by-step explanation:

Hey there! I can definitely explain :)

-2/3a+5/6a-1/6

Multiply the two terms (the first two), to have common denominators!

The common lowest (easiest to deal with) denominator is 18. So, multiply the first term (-2/3a) by 6/6 and the second term (5/6a) by 3/3!

-12/18a+15/18a-1/6

Now, add those together!

3/18a-1/6

Now simplify!

1/6a-1/6

If you want, you can solve for a!

1/6a=1/6

a=1

Hope this helps! Please mark brainliest :)

Which phrase best describes the translation from the graph y=(x-5)^2+7 to the graph of y=(x+1)^2-2

Helga [31]

Start from the parent function $f(x)=x^2$

In the first case, you are computing

$f(x-5)+7$

In the second case, you are computing

$f(x+1)-2 /tex] There are two translation going on: when you transform [tex] f(x) \to f(x+k)$ , you translate the function horizontally, $k$ units left if $k>0$ and $k$ units right if $k$ .

On the other hand, when you transform $f(x) \to f(x)+k$ , you translate the function vertically, $k$ units up if $k>0$ and $k$ units down if $k$ .

So, the first function is the "original" parabola $f(x)=x^2$ , translated $5$ units right and $7$ units up. Likewise, the second function is the "original" parabola $f(x)=x^2$ , translated $1$ units left and $2$ units down.
