Answer:hello :

let : y = f(x)

you have : y = x² + 5

calculate : x

x² =  y - 5

x  exsit for : y - 5 ≥ 0

if : x  ≥ 0    x = √( y - 5)  so the inverse functio for f is : g(x) = √( x - 5)

if : x  ≤ 0    x = - √( y - 5)  so the inverse functio for f is :h(x) = -  √( x - 5)

Describe a situation that fits each equation. Describe more than one situation for each equation, if possible.
lisabon 2012 [21]

Answer:

Step-by-step explanation:

4x − 1 = 19

solving for x, x = 5

2x − 4 = 10

x=7

2x + 2y = 48

x=24-7

y=24-x

5x + 2y = 90

x=18-2y/5

y=45-5x/2

all the situations I could find hope this helps for each equation.

Round each measurement to the nearest ten. Then estimate the area of the rectangle.
Ainat [17]

Answer:

4000 sq inches

Step-by-step explanation:

A rectangle is given with sides 82 and 46 inches

We have to round off these dimensions to the nearest 10.

82 inches ~80 inches since 2 <5, we make it 0

Similarly 46 inches ~50 inches since 6>5

Now area

= length x width

=80(50)

=4000 square inches

Option 2 4000 sq inches is correct answer.

How many license plates in Ontario were registered between the following licence plates? As the question is asking for plates be
Liono4ka [1.6K]

The number of plates is an illustration of permutation and combination

The number of plates is 2592

<h3>How to determine the number of plates</h3>

The range is given as: AVVJ 144 To: BVNP 199 (exclusive)

From the range, we have the following highlights:

  • The first letter can be either A or B (i.e. 2 letters)
  • The second letter can be only V (i.e. 1 letter)
  • The third letter can be from W to M (24 letters)
  • There are 54 numbers between 144 and 199

The number of plates (n) is then calculated as:

n = 2 * 1 * 24 * 54

Evaluate the product

n = 2592

Hence, the number of plates (n) is 2592
