Answer:

OPTION C: h(x) = x - 3

Step-by-step explanation:

To find the inverse of the function y = x + 3.

Swap 'x' and 'y'.

We get x = y + 3.

Solve for 'y' now.

We get y = x - 3

Therefore, the inverse function becomes h(x) = x - 3.

Answer:

7/897 or .0078

Step-by-step explanation:

897/7

897 cannot fit into 7 so move the decimal place over 3 times.

897/7000

897 can go into 7,000 7 times

897/7000

-6279

________

721

Then since 897 cannot go into 721 you drop down a zero and make it 7,210.

897/70000

-6279

________

7210

897 can go into 7,210 8 times.

.0078 is your final answer.

The length of a rectangle is the sum of the width and 4. The area of the rectangle is 32

Sauron [17]

Answer:

The width of rectangle w = 4 units

Step-by-step explanation:

We are given:

Width of rectangle = w

Length of rectangle = w+ 4

Area of rectangle = 32 units

We need to find width of the rectangle

The formula used is: $Area\:of\:rectangle=Length\times Width$

Putting values and finding width of rectangle

$Area\:of\:rectangle=Length\times Width\\32=(w+4)\times w\\32=w^2+4w\\w^2+4w-32=0$

We need to solve this quadratic equation to find width (w)

We will use factorisation and break the middle term.

$w^2+4w-32=0\\w^2+8w-4w-32=0\\w(w+8)-4(w+8)=0\\(w-4)(w+8)=0\\w-4=0\:or\:w+8=0\\w=4\:or\:w=-8$

Since width of rectangle can't be negative, so rejecting w=-8

Therefore, the width of rectangle w = 4 units

Help me please with math

Let's make a table of differences

0 3 8 15 24

3 5 7 9

2 2 2

Constant second difference means a quadratic polynomial,

f(n)=an² + bn +c

f(1)=0, f(2)=3, f(3)=8

0 = a+b+c

3 = 4a + 2b + c

8 = 9a + 3b + c

Subtracting pairs

3 = 3a+b

5 = 5a + b

Subtracting,

2 = 2a

a = 1

b = 5 - 5a = 0

c = -a-b = -1

f(n)=n² -1

Duh, shoulda noticed that at the beginning.

f(17)=17²-1 = 288

a₁ =5

aₙ = aₙ₋₁ - 7

aₙ = a₁ + d(n-1)

aₙ = 5 - 7(n-1)

a₇ = 5 - 7(6) = -37

Answer: -37

How to solve -13 - ¼h = 7

Svetlanka [38]

Answer h=-80
vvv STEP BY STEP vvv
Multiply both sides of the equation by
52-h=28

Move constant to the right-hand side and change its sign
-h=28+52

Add the numbers
-h=80

Change the signs on both sides of the equation
h=-80
