Answer:

negative infinity

Step-by-step explanation:

f(x) = 3 x^7

As x approaches - infinity we do not care about the 3 since it is positive

f(-inf) = (- inf)^7

We can take the negative out since it is to a negative power

f(-inf) = - (inf)^7

inf raised to a power is still infinity

F(-inf) = - inf

It will approach negative infinity

the area of a desktop is represented by x^2 - 49. find the dimensions of the desktop in terms of x. show work please.

Levart [38]

Answer:

The dimensions of the desktop are (x+7) units by (x-7) units

Step-by-step explanation:

we know that

The difference of squares is equal to

$a^2-b^2=(a+b)(a-b)$

we have

$x^2-49$

Remember that

$49=7^2$

substitute

$x^2-7^2$

Applying difference of squares

$x^2-7^2=(x+7)(x-7)$

therefore

The dimensions of the desktop are (x+7) units by (x-7) units

Solve the following system of equations using matrices (row operations).

Stells [14]

Answer:

(6,3,0)

Step-by-step explanation:

Given,

x - y + 0z = 3

6x - 0y - 2z = 36

0x + 6y + 2z = 18

You have the following augmented matrix:

(1) 1 -1 0 3

(2) 6 0 -2 36

(3) 0 6 2 18

Let's (3) add to (2) and divide by 6

(1) 1 -1 0 3

(2) 1 1 0 9

(3) 0 6 2 18

Now, let's (2) add to (1) and divide by 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 6 2 18

Let's (3) ÷ 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 3 1 9

Let's (1) subtract from (2)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 3 1 9

Finally, let's (2) multiply by 3 and subtract from (3)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 0 1 0

Thus,

x = 6, y = 3 and z = 0

The answer is (6, 3, 0)

We have to verify the answer

6 - 3 = 3 ⇒⇒ 3 = 3

6*6 - 5*0 = 36 ⇒⇒ 36 = 36

6*3 + 2*0 = 18 ⇒⇒ 18 = 18
