Help me solve this problem please

Answers

Answer: (2, -2)

x=2, y=-2

Answer:

(2, -2)

Step-by-step explanation:

4x + y = 6

x - 2y = 6

x = 2y + 6

4(2y + 6) + y = 6

8y + 24 + y = 6

9y + 24 = 6

9y = 6 - 24

9y = -18

y = -18 ÷ 9

y = -2

4x + (-2) = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = 8 ÷ 4

x = 2

Confirm:

4x + y = 6

4(2) - 2 = 6

8 - 2 = 6

6 = 6 (Correct)

One morning, Muhammad's deli shop sells 15 sandwiches in 10 minutes. If the shop continues to sell sandwiches at the same rate, about how many sandwiches will the shop sell in 3/4 of an hour?

Answers

Answer:

68 sandwiches

Step-by-step explanation:

Given that,

A shop sells 15 sandwiches in 10 minutes.

10 minutes = (10/60) hour = (1/6) hour

In (1/6) hour shop sells 15 sandwiches

In 1 hour = 90 sandwiches

To find, no of sandwiches in 3/4 hours, multiply 3/4 by 90. So,

In 3/4 hour = [tex]90\times \dfrac{3}{4}=67.5[/tex] sandwiches

or

≅ 68 sandwiches

So, 68 sandwiches can be made in 3/4 hour.

Suppose sin(x) = -3/5 and cos(x) < 0. What the value of cos(2x)?

A) -16/25
B) -7/25
C) 7/25
D) 16/25

Answers

Answer:

The value of cos(2x) = 7/25

Hence, option C is true.

Step-by-step explanation:

Using the trigonometric identity

cos 2x = 1 - 2sin²x

Given

sin(x) = -3/5cos(x) < 0

so substituting the values

cos 2x = 1 - 2sin²x

           = 1 - 2 (-3/5)²

           = 1 - 2 (9/25)

           = 1 - 18/25

           = 7/25

Therefore,

The value of cos(2x) = 7/25

Hence, option C is true.
