3(4a+9)-10(a-6)
(distribute)
12a+27-10a+60
(add common terms)
2a+87
(have x be alone on one side of the equation, in this case by subtracting 87 from both sides)
2a=-87
(divide both sides by 2)
a=43.5

W-4=-12-3w solve for w
lyudmila [28]

w-4=-12-3w

Add 12 to each side:

w + 8 = -3w

Subtract 1w from each side:

8 = -4w

Divide both sides by -4:

w = 8 / -4

w = -2

Just answer no need to explain.
Bogdan [553]
Shifting to left mean adding the number from each occurrence of x from the given function.

So, shifting x³ , 3 units to left will result in:

f(x) = (x + 3)³

Shifting down means subtracting the number from the function value. 

So, shifting 2 units down will result in:

f(x) = (x + 3)³ - 2

Therefore, option A is the correct graph
