Solve the simultaneous equation:<br> 2x - y= 2<br> 3y= 4x - 5
Ronch [10]

Answer:

x = \frac{1}{2} , y = -1

<u>Explanation</u>:

2x - y= 2

3y= 4x - 5

<u>Make y the subject:</u>

2x - y= 2

-y = 2 - 2x

y = 2x - 2  <em>.........equation 1 </em>

3y= 4x - 5

y = (4x - 5)/3<em> ........equation 2</em>

From equation 1 and 2 solve them simultaneously:

→ (4x - 5)/3 =  2x - 2

→ 4x - 5=  3(2x - 2)

→ 4x - 5 = 6x - 6

→ 6x - 4x = -5 + 6

→ 2x = 1

→ x = 1/2

  • if x is 1/2, then y: 2x - 2

                              →  2(1/2)-2

                              →  -1

Find the measure of the angle, PLEASE I NEED HELP-
mafiozo [28]

Answer: A.82

have: x + 105 + x + 89 = 180

⇔ 2x + 194 = 180

⇔ 2x = 180 - 194 = -14

⇔ x = -14/2 = -7

=>  the measure of the angle is -7 + 89 = 82

nikklg [1K]

Answer:

The statement can be expressed as

There are two different students in your class who have visited the same websites.

Step-by-step explanation:

Given that

- W(x, y) mean that student x has visited website y.

- The domain of x consists of all students in your school

- The domain of y consists of all website.

It would help to know the meaning of the symbols used, this will help understand the statement better.

- ∧ means conjuction

- ∃ means 'there exists'

- ∀ means 'for all'

- ≠ means 'different from'

- ↔ means 'if and only if'

The statement

∃x∃y∀z((x ≠ y) ∧ (W(x, z) ↔ W(y, z)))

can be expressed as:

There are two different students in your class who have visited the same websites.
