Answer 1

Answer:

x=2

y=0

Step-by-step explanation:

8x - 4y = 16

solve for x

8x = 4y + 16

divide 8 by all terms

x = 2 + [tex]\frac{y}{2}[/tex]

Insert x in second equation

8(2+y/2)+4y=16

solve

y=0

x=2

the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the number of pencils in stock in 650

Answers

Answer:

Number of pencils in stock = 1200

Average number of pencils sold by the manager per day = 24

Number of pencils that would be sold before reordering = 1200 - 500

                                                                                        = 700

Then

The number of days after which the manager will reorder = 700/24

                                                                                            = 29.16

So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.

a) Find the value of f(10)
b) Find g-'(x)
c) Show that ff(x) = 9x - 48​

Answers

Answer:

a) f(10) = 18

b) g-¹(x) = 5x-5

c) 3((3(x-4))

= 3((3x-12)-4))

= 3(3x-16)

= 9x-48

The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48​

What is function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given that, The functions f and g are such that f(x) = 3(x – 4) and

g(x) = x/5+1

a) f(10) = 3(10-4)

= 3(6)

= 18

b) g'(x) = d/dx(x/5+1)

= 1/5d/dx(x) = 1/5

c) ff(x) =

= 3((3(x-4))

= 3((3x-12)-4))

= 3(3x-16)

= 9x-48

Hence, The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48​

Which expression can you substitute in the indicated equation to solve the system below 5x+y =8 x+4y=2

Answers

Answer:

x = 1.58 and y = 0.105

Step-by-step explanation:

Given equations are :

5x+y =8 ...(1)

x+4y=2 ...(2)

Multiply equation (2) by 5.

5x+20y=10 ..(3)

Subtract equation (1) from (3).

5x+20y-(5x+y) = 10-8

5x+20y-5x-y = 2

19y = 2

y = 0.105

Put the value of y in equation (2).

x+4(0.105)=2

x = 2-0.42

x = 1.58

Hence, the values of x and y are 1.58 and 0.105.
