Solve the system by using elementary row operations on the equations. Follow the systematic elimination procedure.

Natali5045456 [20]

Answer:

Step-by-step explanation:

The given equation is expressed as

x1 + 2x2 = -24- - - - - - - - --1

x1 + 7x2 = -11- - - - - - - --2

We would eliminate x1 by subtracting equation 2 from equation 1. It becomes

- 5x2 = - 13

Dividing both sides of the equation by - 5, it becomes

- 5x2/- 5 = - 13/- 5

x2 = 13/5

Substituting x2 = 13/5 into equation 2, it becomes

x1 + 7 × 13/5 = -11

x1 + 91/5 = - 11

x1 = - 11 - 91/5

x1 = - 146/5

On the first visit to the veterinarian's office, Cora's kitten weighted 550 grams.

tamaranim1 [39]

old (first visit): 550 grams

second visit: gained 350 grams

third visit: gained 300 grams

new: cora's kitten is now 1200 grams.

-> now, we must find the percent increase between 550 and 1200.

to find percent increase, we use this equation

new - old / old x 100

-> (1200 - 550 / 550) x 100

(650 / 550) x 100

= 1.18 x 100

percent increase: 118%

Find the maximum production level p = 100x^{0.34}y^{0.66} if the total cost of labor (at $72 per unit) and capital (at $40 per u

Anton [14]

Maximum production p=552728

Step-by-step explanation:

The equation for maximum production is : $p=100x^{0.34} y^{0.66}$

The number of units of labor is x @$72

The number of units of capital is y @$40

The total cost of labor and capital is limited to $270,000, this can be written as;

72x+40y ≤ $270,000

Graphing the inequality to find values of x and y ,from the graph;

x=3750 units

y=6750 units

Applying the expression for maximum production

$p=100*x^{0.34}* y^{0.66} \\\\p=100*3750^{0.34} *6750^{0.66} \\\\p=552727.56\\\\p=552728$
