how would I solve the system x + 2y = 13, -x + y = 5 when using elimination

Answers

Answer:

x + 2y = 13}(add the both eqns)

-x + y = 5}

x +(-x) = 0

2y + y = 3y

13 + 5 = 18

then,

3y = 18

y = 6

from

x + 2y = 13

x = 13 - 2(6)

x = 1

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please

Answers

Answer:

Constant of variation: 1/4

Slope of the line: 1/4

Step-by-step explanation:

The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

finding the x- and y- intercepts of 50x-5y =25

Answers

Answer:

y = 5.00000

x = 0.50000

x - intercept is the value of x when y equals zero

50x - 5y = 25
50x - 5(0)= 25
50x = 25
x = 0.5

y - intercept is the value of y when x equals zero

50x - 5y = 25
50(0)- 5y = 25
- 5y = 25
y = -5

What is the total cost for x months?c.Graph the cost of the cell phone plan over a period of two years using month as the units of time be sure to label your axes and scale them by labeling each grid line with a number.d.Is there a portions relationship between time and the cost of the cell phone plan.e. Draw a line a parallel to the line you graphed that goes through the point(0,350) suppose that this line represents the pricing plan for another company.What is the startup fee and monthly cost for this plan?

Answers

Answer:

a. $250

b. The total cost for x month is $200 + $50 × x

c. Please see the attached graph

d. Yes, there is a proportional relationship between time and the cost of the cell phone plan

e. $350

Step-by-step explanation:

The given parameters are;

The costs to start on the cell phone cell = $200

The charge each month = $50

a. The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge = $200 + $50 = $250

b. The total cost for x month, c = $200 + $50 × x

c. Please see the attached graph

d. Yes, there is a proportional relationship between time and the cost of the cell phone plan

e. The line parallel to the line graphed that goes to the point (0, 350), is given as follows;

y = m·x + c

Where;

m = 50

y - 350 = 50 × (x - 0)

y = 50·x + 350

The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;

c = 50 × 0 + 350 = 350

The startup fee for the pricing plan = $350.

The startup fee and monthly cost for this plan according to the question is :

Part a:

The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge

Total Cost = $200 + $50 Total Cost = $250 The total cost to use the cell phone plan for 1 month is $250.

Part b:

The total cost for x month, c = $200 + $50 × x The total cost for x month is $200 + $50 × x c.

Please see the attached graph

Part c:

Yes, there is a proportional relationship between time and the cost of the cell phone plan .

Part e:

The line parallel to the line graphed that goes to the point (0, 350), is given as follows;

y = m·x + c

Where;

m = 50 y - 350 = 50 × (x - 0) y = 50·x + 350

The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;

c = 50 × 0 + 350 = 350

Yes, there is a proportional relationship between time and the cost of the cell phone plan e. $350

The given parameters are; The costs to start on the cell phone cell = $200 The charge each month = $50

The startup fee for the pricing plan = $350.

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.

Answers

Answer:

the answer is 0.204

Step-by-step explanation:

The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

How to determine the probability?

The probability that a tire is defect is given as:

p = 5%

The required probability is then calculated using:

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Where:

n = 5 --- number of tires

x = 1 ---number of tires with defect

So, we have:'

[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]

This gives

[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]

Evaluate the product

P(1) = 0.204

Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

What is 35a + 14 = 1

Answers

Answer:

a = -13/35

Step-by-step explanation:

35a + 14 = 1

(given)

_________

35a + 14 = 1

- 14 -14

(subtraction property of equality)

(subtract 14 from both sides to isolate the 35a term)

_________

35a = -13

÷35 ÷35

(division property of equality)

(divide by 35 on both sides to remove the coefficient of 35 in 35a)

_________

a = -13/35

35a+14=1

35a+14 - 14 = 1 - 14

35a= -13

35a = -13

35 35

Answers

Answer:

A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla

entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100

en mi primera ecuación seria: 4X + 3Y = 14.100

ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla

en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:

primera ecuación: 4X + 3Y = 14.100

segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1

al sumarlas obtengo como resultado: -5X = -12

resolviendo esa ecuacion obtengo que X=

X=2.4

luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100

reemplazando seria: 4 x (2.4) + 3Y =14.100

9.6 + 3Y = 14.1000

3Y= 14.100 - 9.6

Y=1.5

entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $
