Y = -2x -1 and x = -2

Simply plug in -2 for x in our given equation :)

y = -2(-2) - 1 

Simplify.

y = 4 - 1

Simplify.

So, y =3

x = -2, y = 3

To check our work, simply plug -2 in for x, and 3 in for y.

y = -2x - 1

(3) = -2(-2) - 1

Simplify.

3 = 4 - 1

3 = 3

Therefore, x = -2, y = 3

~Hope I helped!~

Answer:

  A'(-4, -2), B'(4, -7), C'(5, -1)

Step-by-step explanation:

Reflection in the x-axis changes the sign of each y-coordinate.

  (x, y) ⇒ (x, -y)

  A(-4, 2) ⇒ A'(-4, -2)

  B(4, 7) ⇒ B'(4, -7)

  C(5, 1) ⇒ C'(5, -1)

Mandarinka [93]

Answer:

e. the labor cost for a drone assembled at overtime would be $75.33.

Step-by-step explanation:

From given data

income of a single PAT member is $22,000+$800+$3,200=$26,000

The annual income of 4 PAT members is 4*($26,000) = $1,04,000 --------->(1)

and also a PAT is paid a $6 assembly quality incentive per UAV drone assembled that is equally divided among 4 PAT members.

And the Quality incentive per UAV drone for 4 PAT members = $6, and as the PAT's productivity is 1500 drones per year.

The total Annual Quality incentive for 4 PAT members = 1500*($6) = $9,000 --------->(2)

Hence, the Company invests a total labor cost of $1,04,000 + $9,000 [From, (1)+(2)], for 1500 drones

Thus, the Company invests a total labor cost of $1,13,000 for 1500 drones

Thus, for each drone the investment for the labor cost becomes ($1,13,000) / 1500 = $75.33

Hence, the labor cost for a drone assembled is $75.33

e. the labor cost for a drone assembled at overtime would be $75.33 is the answer

Given: AB tangent at D, AD = OD = 4 Find: Area of the shaded region
MrMuchimi

Answer:

1.72

Step-by-step explanation:

AB tangent at D, AD = OD = 4

so triangle OAD is right angle with side of 4 and 4.

area of OAD = 1/2 * 4 * 4 = 8

Angle AOD = DAO = 45 deg.

so circular sector OCD area = area of circle O * 45/360

= pi * 4 * 4 * 45/360

= 2pi

Shade area ACD = trigangle OAD - circular sector OCD

= 8 - 2pi

= 1.72
