Answer:

It is extremely easy. You just have to substitute the function value of variable "x" back into the original expression to directly obtain the answer for a specific "set value" for a variable of "x". Here they have asked for function of "x" and replaced the function for variable "x" to a value.

For the first one. The function of "x" is replaced by the value of "5". Substitute this value into the original functional expression to obtain the answer. So:

1)

2)

3)

The final answers are given and we can deduce the options for those three questions.

1) Option C) 14.

2) Option C) 2.

3) Option C) 9.

Hope it helps.

It is extremely easy. You just have to substitute the function value of variable "x" back into the original expression to directly obtain the answer for a specific "set value" for a variable of "x". Here they have asked for function of "x" and replaced the function for variable "x" to a value.

For the first one. The function of "x" is replaced by the value of "5". Substitute this value into the original functional expression to obtain the answer. So:

1) \mathbf{Since, \: f(x) = 4x - 6}

\mathbf{\therefore \quad f(5) = 4 \times 5 - 6}

\mathbf{f(5) = 20 - 6}

\boxed{\mathbf{\therefore \quad Final \: \: Answer, \: f(5) = 14}}


2) \mathbf{Since, \: g(x) = x - 7}

\mathbf{\therefore \quad g(5) = 5 - 7}

\boxed{\mathbf{\therefore \quad Final \: \: Answer, \: g(5) = 2}}


3) \mathbf{Since, \: g(x) = x^2}

\mathbf{\therefore \quad g(3) = 3^2}

\boxed{\mathbf{\therefore \quad Final \: \: Answer, \: g(3) = 9}}


The final answers are given and we can deduce the options for those three questions.


1) Option C) 14.

2) Option C) 2.

3) Option C) 9.

NEED HELP WITH A MATH QUESTION
Lady_Fox [76]

Answer:

\dfrac{18}{5}

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

\dfrac{18}{5}

<h3>Answer:  Choice D)  7.5 cm</h3>

==========================================================

Explanation:

We are told that quadrilateral ABCD is similar to quadrilateral EFGH.

The order of the four letter sequence is important.

  • For ABCD, we have AB as the first pair of letters.
  • For EFGH, we have EF as the first pair of letters.

Therefore, AB and EF are corresponding sides.

So AB = 10 and EF = x pair up together. We can form the ratio AB/EF which becomes 10/x.

The diagram shows that AD = 8. Notice that A and D are the first and last letters of ABCD. The first and last letters of EFGH are E and H. We can see that AD and EH correspond to one another because of this.

AD = 8 and EH = 6 forming the ratio AD/EH = 8/6

Because the quadrilaterals are similar, the corresponding ratios must be the same. Therefore, AB/EF is the same as AD/EH.

-----------------------

Let's set up a proportion to solve for x

AB/EF = AD/EH

10/x = 8/6

10*6 = x*8

60 = 8x

8x = 60

x = 60/8

x = 7.5  Answer is choice D

A garrison of 400men had food for 40days.After 10 days,200 more men joined them .How long will the food last now?(Assume that th
mestny [16]

Let x be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.

400\cdot 40\cdot x = 16000x

After 10 days, the 400 men will have consumed

400\cdot 10\cdot x = 4000x

food, impliying that the food remaining is

16000x-4000x=12000x

If 200 more men join the garrison, there are now 600 men. Each of them requires x food each day, and there are 12000x units of food remaining. They will last

\dfrac{12000x}{600}=20 days.
