Answer: B

The piece wise functions first part says: x is less than it equal to one and has a vertical shift down 4. which would mean the circle is closed and shaded down.

The second part of the function says x is greater than one and has a vertical shift up 3. This would mean it is an open circle and is shaded up.

Answer:

a) 6
b) 3t² - 17t + 28
c) 3t² - 5t - 2

Step-by-step explanation:

<u>Given function:</u>

g(t) = 3t² - 5t + 4

a) g(2)

g(2) = 3*2² - 5*2 + 4 =
3*4 - 10 + 4 =
12 - 6 =
6

b) g(t - 2)

g(t - 2) = 3(t - 2)² - 5(t - 2) + 4 =
3(t² - 4t + 4) - 5t + 10 + 4 =
3t² - 12t + 12 - 5t + 16 =
3t² - 17t + 28

c) g(t) - g(2)

g(t) - g(2) = 3t² - 5t + 4 - 6 =
3t² - 5t - 2

The governor of a state earns $54,625 more than the governor of state B. If the total of their salaries is 286,165, find the sal

Kitty [74]

For this case, the first thing we must do is define variables.
We have then:
x: governor of a state gains
y: governor of b state earnings
We now write the system of equations that models the problem.
We have then:
$x + y = 286165

x = y + 54625$
Solving the system of equations we have:
$y + 54625 + y = 286165

2y = 286165 - 54625

2y = 231540

y = 231540/2

y = 115770$
Then, for x:
$x = y + 54625

x = 115770 + 54625

x = 170395$
Answer: governor of a state earns $ 170395
governor of b state earns $ 115770

The bearing of point B from point A is 037º.

Leni [432]

Answer:

217 degrees

Step-by-step explanation:

interior angles add up to 180, so 180-37=143 degrees

angles at a point add up to 360, so 360-143=217 degrees

1. Subtract and simplify

hodyreva [135]

Step-by-step explanation:

1-(-y^2-4y-8)-(-4y^2-6y+3)

Simplify: 3y^2+2y−11

Subtract: 3y^2+2y-11

2. 2x^2y^3z^2*4xy^4x^2

Simplify: 8x^5y^7z^2

Subtract: 8x^5y^7z^2

3. (x-4) (x^2-5x-6)

Simplify: x^3-9x^2+14x+24

Subtract: x^3-9x^2+14x+24
