For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed

The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a t

PIT_PIT [208]

Answer:

Large box weighs 18.25 kilograms

Small box weighs 15.25 kilograms

Step-by-step explanation:

A fruit company delivers its fruit in two types of boxes: large and small.

Let x = weight of large box.

Let y = weight of small box.

A delivery of 3 large boxes and 5 small boxes has a total weight of 131 kilograms. This means

3x + 5y = 131 - - - - - - - - - - -1

A delivery of 6 large boxes and 2 small boxes has a total weight of 140 kilograms.

This means 6x + 2y = 140 - - - - - - - 2

Solving equation 1 and equation 2 by elimination method,

Multiply equation 1 by 6 and equation 2 by 3

18x + 30y = 786

18x +6y = 420

24y = 366

y = 366/24 = 15.25

Put y = 15.25 in equation 1

3x + 5× 15.25 = 131

3x + 76.25 = 131

3x = 131 - 76.25

3x = 54.75

x = 54.75/3 = 18.25

1. What is (f⋅g)(x)?

nekit [7.7K]

Answer:

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$

Step-by-step explanation:

For the first part of the question we have two functions

$f(x) = x^4 -9$

$g(x) = x^3 + 9$

If the expression refers to the multiplication of f and g, then:

(f⋅g)(x) $= f (x)g(x)$

So we multiply the function f(x) with the function g(x)

(f⋅g)(x) $= (x^4 - 9)(x^3 + 9)$

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

For the second part we have the functions:

$f(x) = x^3 -2x^2 + 12x - 6\\\\g(x) = 4x^2 - 6x + 4$

We wish to find (f - g) (x). We know that

$(f - g)(x) = f(x) - g(x)\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 - [4x^2 - 6x + 4]\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 -4x^2 + 6x - 4$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$
