37-45= -8
The answer is a negative number

No problem!  since 37 is smaller than 45, then your answer will be negative,  so instead, switch the numbers around, making it 45-37.  Now, just find the answer (8), and add a negative.  So your answer is -8.

37-45=x
45-37= -x
45-37=8
47-35=-8

Evaluate i^31 please help
Nadya [2.5K]

ANSWER

{i}^{31}  =  - i

EXPLANATION

We want to evaluate

{i}^{31}

Use indices to rewrite the expression as:

=  {i}^{30}  \times i

We know that

{i}^{2}  =  - 1

So we rewrite the expression to obtain;

=  ({ {i}^{2}) }^{15}  \times i

This gives us;

=   {( - 1) }^{15}  \times i

This simplifies to

=  - 1 \times i

=  - i

For all values of x
Yuliya22 [10]

Answer:

A.) gf(x) = 3x^2 + 12x + 9

B.) g'(x) = 2

Step-by-step explanation:

A.) The two given functions are:

f(x) = (x + 2)^2 and g(x) = 3(x - 1)

Open the bracket of the two functions

f(x) = (x + 2)^2

f(x) = x^2 + 2x + 2x + 4

f(x) = x^2 + 4x + 4

and

g(x) = 3(x - 1)

g(x) = 3x - 3

To find gf(x), substitute f(x) for x in g(x)

gf(x) = 3( x^2 + 4x + 4 ) - 3

gf(x) = 3x^2 + 12x + 12 - 3

gf(x) = 3x^2 + 12x + 9

Where

a = 3, b = 12, c = 9

B.) To find g '(12), you must first find the inverse function of g(x) that is g'(x)

To find g'(x), let g(x) be equal to y. Then, interchange y and x for each other and make y the subject of formula

Y = 3x + 3

X = 3y + 3

Make y the subject of formula

3y = x - 3

Y = x/3 - 3/3

Y = x/3 - 1

Therefore, g'(x) = x/3 - 1

For g'(12), substitute 12 for x in g' (x)

g'(x) = 12/4 - 1

g'(x) = 3 - 1

g'(x) = 2.

X-Y-2Z =-11<br> X-2Y-Z = -11 <br> -X+Y+3Z = 14
Snowcat [4.5K]

9514 1404 393

Answer:

  (X, Y, Z) = (-2, 3, 3)

Step-by-step explanation:

We can subtract the second equation from the first to get ...

  Y -Z = 0

We can add the third equation to the first to get ...

  Z = 3

Then ...

  Y -3 = 0   ⇒   Y = 3

and ...

  X -3 -2(3) = -11

  X = -2 . . . . . . . . . add 9

The solution is ...

  (X, Y, Z) = (-2, 3, 3)

x + y = 16

x - y = 14     add the equations

--------------

2x = 30

x = 15

x + y = 16
