3x - 2y= 5, 4x + 3y= 1​

Mathematics
2 answers:
Sindrei [870]3 years ago

Answer:

(1, - 1 )

Step-by-step explanation:

Given the 2 equations

3x - 2y = 5 → (1)

4x + 3y = 1 → (2)

Multiplying (1) by 3 and (2) by 2 and adding the result will eliminate y- term

9x - 6y = 15 → (3)

8x + 6y = 2 → (4)

Add (3) and (4) term by term to eliminate y

17x + 0 = 17

17x = 17 ( divide both sides by 17 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

4(1) + 3y = 1

4 + 3y = 1 ( subtract 4 from both sides )

3y = - 3 ( divide both sides by 3 )

y = - 1

solution is (1, - 1 )

Use the given cost table for the same product from two different companies to create a linear system.
viktelen [127]

40 garments need to be dry cleaned for the two companies to have the same cost.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let f(x) represent the cost for dry cleaning at Company 1. Hence using the points:

  • (5, 115.25) and (15, 155.75)

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\&#10; \\&#10;y-115.25=\frac{155.75-115.25}{15-5}(x-5)\\&#10; \\&#10;y=4.05x+95

Let g(x) represent the cost for dry cleaning at Company 2. Hence using the points:

  • (5, 45.25) and (15, 105.75)

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\&#10; \\&#10;y-45.25=\frac{105.75-45.25}{15-5}(x-5)\\&#10; \\&#10;y=6.05x+15

For the cost to be the same:

4.05x + 95= 6.05x + 15

x = 40

40 garments need to be dry cleaned for the two companies to have the same cost.

Find the probability of rolling an even number and then rolling a 6 when a number cube is rolled twice. Enter your answer in sim
love history [14]
We could use the product rule of probabilities in solving this problem. For the first roll, the probability of getting an even number is 3 / 6 = 1/2. For the second roll, the probability of getting a 6 is 1/6. Multiplying both is 1/2 * 1/6 = 1/12.


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

storchak [24]

Answer:

the median is 6 and the mean is 8.375

Step-by-step explanation:

first you have to arrange the numbers from least to greatest the median is the middle number which in this case there are two but both of them are 6 so the median is 6 and for the mean you just average by adding it all together then divide by the total
