Simultaneous linear equations
Talja [164]
<span>1) 3x + y = 23
6x + y = 44

Subtract 1st from 2nd, 
3x = 21
x = 7
Then, y = 23 - 3(7) = 2

In short, Your Answer would be: (7, 2)

2) </span><span>4x - 3y = 21
2x + 3y = 33

Add the equations, 
6x = 54
x = 9
Then, 2(9) + 3y = 33
3y = 33 - 18
y = 15/3
y = 5

In short, Your Answer would be: (9, 5)

3) </span><span>5x + 2y = 13
6y + 5x = 29
Subtract 1st from 2nd equation, 

4y = 16
y = 4
Then, 5x  = 13 - 2(4)
x = 5/5 = 1

In short, Your Answer would be: (1, 4)

4)  </span><span>5x - 4y = 2
10x - 4y = 32
Subtract 1st from 2nd equation, 
5x = 30
x = 6

Then, 5(6) - 2 = 4y
y = 28/4 = 7

In short, Your Answer would be: (6, 7)

5) </span><span>2x + 7y = 48
x + 3y = 21

Here, x = 21-3y
Substitute in in 1st equation, 
2(21-3y) + 7y = 48
42 - 6y + 7y = 48
y = 6

Then, x = 21 - 3(6) = 3

In short, Your Answer would be: (3, 6)

6) </span><span>8x - 3y = 44
2y - 4x = -20

Multiply 2nd equation by 2 
-8x + 4y = -40
Now, add it to 1st equation, 
y = 4

Then, 2(4) - 4x = -20
4x = 8 + 20
x = 28/4 = 7

In short, Your Answer would be: (7, 4)

Hope this helps!</span>

Plz solve this question mhanifa
IrinaK [193]

Answer:

  • Option D

Step-by-step explanation:

<u>Given:</u>

  • f(x) = 1/ (x - 3)
  • g(x) = \sqrt{x+5}

<u>The composite function f · g(x) is:</u>

  • f(g(x)) = 1 / ( \sqrt{x+5}  - 3)

<u>Restrictions are:</u>

  • x + 5 ≥ 0 ⇒ x ≥ - 5

and

  • \sqrt{x+5} ≠ 3 ⇒ x + 5 ≠ 9 ⇒ x ≠ 4

<u>Combination of the above gives us the domain:</u>

  • x ∈ [ - 5, 4) ∪ (4, +∞)

Correct choice is D

What x-value makes the set of ratios equivalent? 2 : 3 = 6 : x 4 : 7 = x : 42 2x : 48 = 3 : 12 12 : 15 = x : 20
Oliga [24]

Answer:

2 : 3 = 6 : x (9)

3 : 12 = 2x : 48 (6)

12 : 15 = x : 20 (16)

4 : 7 = x : 42 (24)
