Determine if the given ordered triple is a solution of the system.

Mathematics

Orlov [11]1 year ago
8 0

Answer:

It is.

Step-by-step explanation:

(x, y, z) => (4, -5, -4)

substitute 4 in x, -5 in y & -4 in z for all the equations in the system.

4x + 2y + z = 2

4(4) + 2(-5) - 4 = 2

2 = 2

5x - 4y - z = 44

5(4) - 4(-5) - (-4) = 44

44 = 44

3x + y + 4z = -9

3(4) + (-5) + 4(-4) = -9

-9 = -9

All equations therefore agree with the ordered triple.

Fill in the table with the next four terms of the sequence a1=4 and an=3an – 1, if n≥2.
Alexeev081 [22]

Answer:

12, 36, 108, 324

Step-by-step explanation:

using the recursive formula and a₁ = 4 , then

a₂ = 3a₁ = 3 × 4 = 12

a₃ = 3a₂ = 3 × 12 = 36

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324

If f(x)=3x +10 and g(x)= 2x-4 fjnd (f-g)(x)
lina2011 [118]

The value of (f-g)(x) is x + 14.

<h3>What is Function?</h3>

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.

Here, given function;

f(x) = 3x + 10  and  g(x) = 2x - 4

Now,

  (f - g)(x) = f(x) - g(x)

                = (3x + 10) - (2x - 4)

                = 3x + 10 - 2x + 4

                = (3x - 2x) + (10 + 4)

  (f - g)(x) = x + 14

Thus, the value of (f-g)(x) is x + 14.
