Mathematics
1 answer:
givi [52]3 years ago
8 0

Answer:

There are an infinite number of solutions to this equation. One of which would be (-2, -1)

Step-by-step explanation:

In order to find any solution, start by picking a value for x. For the purpose of this exercise, we'll select -2. Now input that in for x and solve for y. The resulting ordered pair is a solution.

4x - 7y = -1

4(-2) - 7y = -1

-8 - 7y = -1

-7y = 7

y = -1

Answer: x = 8

Step-by-step explanation:

Hello again XD.

This is a coordinate plane and all the angles on a coordinate plane add up to 360°

Divide 360 by 4 to get the measurement of the section we are working in.

360/4 = 90°

This means it is complementary and complementary angles state that both separate angles added together = 90°

therefore,

6x + 2 + 40 = 90

combine like terms:

6x + 42 = 90

now subtract 42 from both sides

6x = 48

divide 6 from both sides to get:

x = 8

Let me know if you have any more questions you want answered and I hope I explained this well.

If y varies inversely as x, and y = 10 when x = 20,<br> find x when y = 16.
Ipatiy [6.2K]

Answer:

12.5

Step-by-step explanation:

y varies inversely as x.

y = k/x

10 = k/20

200 = k

The constant proportion k is 200.

16 = 200/x

Cross multiply.

200 = 16x

200/16 = x

x = 12.5
