which set of steps shows the solution to the equation 2y = −8? y = −8 − 2; y = 6 y = −8 ÷ (−2); y = 4 y = −8 ÷ 2; y = −4 y = −8

xz_007 [3.2K]

Answer: The correct option is

(C) y = −8 ÷ 2; y = −4.

Step-by-step explanation: We are given to select the correct steps that shows the solution to the following equation :

$2y=-8~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

the solution to the equation $ax=b,~~\textup{a,b are real numbers}$ is given by

$ax=b\\\\\Rightarrow x=b\div a.$

Therefore, the solution of equation (i) is as follows :

$2y=-8\\\\\Rightarrow y=-8\div 2\\\\\Rightarrow y=\dfrac{-8}{2}\\\\\Rightarrow y=-4.$

Thus, (C) is the correct option.

Assume that MTA Sandwiches sells sandwiches for $2.85 each. The cost of each sandwich follows:

mixas84 [53]

Answer:

a. profit is lower

b. lowest price $2.29

Step-by-step explanation:

a. We have to analyze how this especial order affect the profit of the company

Profit = Revenue- Total cost = P(x) =(Px * Q)-(FC + vc*Q)

Regular production profit= $2.85 x 18,400 units -$2.60 x 18,400 units=

Regular production profit=4600

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)

P2= price of special order

Q2= quantity of special order

Q= Q1 +Q2

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)= $2.85 x 18,400 units +$1.85 x 800 units - $18,400- $1.60 x 19600=

Production with special order= 51888 +1480- $18,400- 30720

Production with special order= 4.248‬

b.Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q) =4600

=51888 +(P2 * 800)- $18,400- 30720 =4600

=(P2 * 800)= 4600- 51888 + $18,400+30720

P2=1.832/800 = 2,29

AB is a straight line workout the size of angle X

Hoochie [10]

The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.

Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.

The straight line formed a 180° angle. The resulting equation is as follows:

⇒x+42°+29°=180°

⇒x=109°

Hence, the value of the x will be 109°

The complete question is:

AB is a straight line.

Work out the size of angle x.

Not drawn accurately

42°

29°
