Answer:

-18=2x-3(-1/3x+3)

-18=2x+x-9

-18=3x-9

-18+9=3x

3x=-9

x=-9

y=-3(-1/3)+3

y=1+3

y=4

Karmin will make $18.4 for working an hour after the increase.

Step-by-step explanation:

Step 1:

First, we need to determine how much Karmin made an hour.

Karmin's hourly rate = \frac{480}{30} = 16.

So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.

She will get a 15% increase in her hourly rate this month.

Step 2:

We need to determine how much 15% of $16 is.

15% of $16 = \frac{15}{100} (16) = 0.15 (16)= 2.4.

So her 15% increase amounts to $2.4.

So the hourly rate for this month 16 + 2.4 = 18.4.

So Karmin will make $18.4 for working 1 hour.

The functions f(x) = (x + 1)2 - 5 and g(x) = -(x - 2)2 + 3 have been rewritten using the completing-the-square method. What is t
emmasim [6.3K]

f(x) has vertex = (- 1, - 5 ) and is a minimum

g(x) has vertex = (2, 3 ) and is a maximum

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum

to determine if maximum/ minimum

• if a > 0 then minimum

• if a < 0 then maximum

g(x) = - (x - 2)² + 3 is also in vertex form with a < 0

vertex = (2, 3 ) and is a maximum
