Answer:

Question 1:

(3)

x     3  5  7  9  

f(x)  2  4  2  4

Question 2:

(2) whole numbers

Step-by-step explanation:

1.

In a function, each x-value must only have 1 y-value, but a y-value can have multiple x-values.

2.

A whole number is any positive number that is not a fraction. You cannot have negative devices nor a fraction of a device.

Solve 4a = 20
olya-2409 [2.1K]

Here's the solutions :

1. solve for a :

  • 4a = 20

  • a =  \dfrac{20}{4}

  • a = 5

2. solve for y :

  • 3y + 9 = 24

  • 3y = 24 - 9

  • 3y = 15

  • y =  \dfrac{15}{3}

  • y = 5

3. solve for y :

  • \dfrac{y}{3}  - 5 = 4

  • \dfrac{y}{3}  = 5 + 4

  • \dfrac{y}{3}  = 9

  • y = 9 \times 3

  • y = 27

4. solve for k :

  • 3 = 9 -  4k

  • 3 - 9 =  -4 k

  • - 6 =  - 4 k

  • k =  \dfrac{ - 6}{ - 4}

  • k =  \dfrac{3}{2}  \:  \:  \: or \:  \: 1.5

5. there's something wrong with this question.

6. solve for x :

  • 3x + 8 = 2

  • 3x = 2 - 8

  • 3x =  - 6

  • x =  \dfrac{ - 6}{3}

  • x =  - 2

i hope it helped...

Looking at this problem in terms of geometry makes it easier than trying to think of it algebraically.

If you want the largest possible x+y, it's equivalent to finding a rectangle with width x and length y that has the largest perimeter.

If you want the smallest possible x+y, it's equivalent to finding the rectangle with the smallest perimeter.

However, the area x*y must be constant and = 100.

We know that a square has the smallest perimeter to area ratio. This means that the smallest perimeter rectangle with area 100 is a square with side length 10. For this square, x+y = 20.

We also know that the further the rectangle stretches, the larger its perimeter to area ratio becomes. This means that a rectangle with side lengths 100 and 1 with an area of 100 has the largest perimeter. For this rectangle, x+y = 101.

So, the difference between the max and min values of x+y = 101 - 20 = 81.

For the first 80 miles of her road trip, Lina travels 10 miles/hour slower than she did for the remaining 50 miles of her trip.
Contact [7]

The expressions represent the total time of her trip in hours is\rm \dfrac{80}{s} + \dfrac{50}{s+10}.

Given that,

For the first 80 miles of her road trip, Lina travels 10 miles/hour slower than she did for the remaining 50 miles of her trip.

It represents Lina's  speed during the first part of her trip.

We have to determine,

Which expressions represent the total time of her trip in hours?

According to the question,

Let the speed traveled during the first part of the trip be "s".

The formula for calculating the distance is expressed as:

\rm Distance = Speed \times Time

For the first part of the journey:

Distance = 80 miles

Time = \rm t_1

And Speed = s

Substitute all the values in the formula,

\rm Distance = Speed \times Time\\\\80 = s \times t_1\\\\ t_1= \dfrac{80}{s}

For the second part of the trip;

Distance traveled = 50 miles

Speed = s + 10 (10miles/hour faster than the first part of the trip)

time = \rm t_2

Substitute all the values in the formula,

\rm Distance = Speed \times Time\\\\50 = (s+10) \times t_2\\\\ t_2 = \dfrac{50}{s+10}

Therefore,

Adding both the time to represent the total time of her trip in hours,

\rm = t_1 +t_2 \\\\ = \dfrac{80}{s} + \dfrac{50}{s+10}

Hence, The required expressions represent the total time of her trip in hours is\rm \dfrac{80}{s} + \dfrac{50}{s+10}.
