Which expression is equivalent to 11(17 – x)?A.


11 • 17 – 11x


B.


17 – 11x


C.


11 • 17 – x


D.


11 + 17 – x

Answers

Answer 1
Answer: The answer is A. 11 x 17 - 11x because you would use the distributive property and multiply the number on the outside (11) by everything on the inside (17 and -x)
Answer 2
Answer: for this, they are asking you to multiply both 17 and -x by 11. B and C only multiply one term by 11, and D doesn't multiply at all. A is the only one that fits!

Find the arithmetic combination of f(x) =x+2, g(x)=x-2

Answers

Answer:

The arithmetic combinations of given functions are (f + g)(x) = 2x, (f - g)(x) = 4,  (f * g)(x) = \mathrm{x}^(2)-4 , \left((f)/(g)\right)(\mathrm{x})=(x+2)/(x-2)

Solution:  

Given, two functions are f(x) = x + 2 and g(x) = x – 2

We need to find the arithmetic combinations of given two functions.

Arithmetic functions of f(x) and g(x) are (f + g)(x), (f – g)(x), (f * g)(x), \left((f)/(g)\right)(\mathrm{x})

Now, (f + g)(x) = f(x) + g(x)

= x + 2 +x – 2

= 2x

Therefore (f + g)(x) = 2x

similarly,

(f - g)(x) = f(x) - g(x)

= x + 2 –(x – 2)

= x + 2 –x + 2

= 4

Therefore (f - g)(x) = 4

similarly,

(f * g)(x) = f(x) * g(x)

= (x + 2) * (x – 2)

= x * (x – 2) + 2 * (x -2)

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

=x^(2)-4

Therefore  (f * g)(x) = x^(2)-4

now,

\left((f)/(g)\right)(\mathrm{x})=(f(x))/(g(x))

=(x+2)/(x-2)

((f)/(g))(x) = (x+2)/(x-2)

Hence arithmetic combinations of given functions are (f + g)(x) = 2x, (f - g)(x) = 4,  (f * g)(x) = \mathrm{x}^(2)-4 , \left((f)/(g)\right)(\mathrm{x})=(x+2)/(x-2)

the gcf of two numbers is equal to the lesser of the numbers? Is this statement always, sometimes, or never true?

Answers

G.C.F is called greatest common factor.It is the  number that divides both the numbers. For example GCF of  2 ad 4 is 2.

GCF of 6 and 9 is 3.

GCF of 8 and 25 is 1. If there is no common number that divides both the numbers then in that case GCF=1.

The statement The gcf of two numbers is equal to the lesser of the numbers is not always but sometimes true.

It's actually sometimes

2. A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and
costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in
dollars, per fluid ounce between the two brands of juice?

Answers

Answers with working:

1.

Cost of a crate of floor tiles = $95.94

The crate has 6 boxes of floor tiles. This means 6 boxes of tiles cost $95.94

Now each box has 20 floor tiles.

So, total tiles in a box are : t=6*20=120 tiles

Now, cost of 6 boxes = $95.94

So, cost of 1 box (b) = b=(95.94)/(6) = $15.99

20 tiles cost $15.99

Hence, 1 tile (t) will cost = (15.99)/(20) = $0.799 ≈ $0.80

2.

Brand A contains 8 fluid ounces and  costs $1.28.

Cost of per fluid ounce = (1.28)/(8) = $0.16

Brand B contains 12 fluid ounces and costs $1.68.

Cost of per ounce = (1.68)/(12) = $0.14

Difference between both the per ounce costs = 0.16-0.14 = $0.02

1. b = $95.94 / 6
       = $15.99

    t = $15.99 / 20
      = $0.80

2. A: $1.28 / 8 = $0.16 per oz
    B: $1.68 / 12 = $0.14 per oz 

    Difference: $0.02 per oz
