Answer:
Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan. If then If then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore Hence, { 19 + 0.39(x - 300), x > 300

Answer:

Step-by-step explanation:
Since our equation is
and we want to solve for G, first we divide both sides by the product
, which gives:

So we are left with:

Now we multiply both sides by
, which gives:

Which gives us our final formula:

Step-by-step explanation:
x²+7x+12
x²+4x+3x+12
x(x+4)+3(x+4)
(x+3)(x+4)

Answer:
u=32
Step-by-step explanation:
Hey There!
Those are a pair of complementary angles we can tell because it has a square at the angle.
When angles are complementary they add up to 90
So given one angle we subtract that by 90 to find the missing angle
90-58=32
therefore u = 32
