Determine the type and number of solutions of 4x^2-5x+1=0.A. Two real solutions
B. One real solution
C. Two imaginary solutions

Answers

4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9

x = - b ± √Δ / 2.a
$x = (-5\± √(9) )/(2*4)$
$x = (-5\±3)/(8)$
$x' = (-5-3)/(8) = (-8)/(8) = -1$
$x' = (-5+3)/(8) = (-2)/(8) (/2) = (-1)/(4)$

A. Two real solutions (x' = -1 and x'' = -1/4)

Factoring the expression 20a^3b^3 – 24a^5b^2 + 4a^3b^2 gives a new expression of the formUa^xb^y (Wa^2 + Vb+ z), where U > 0.

What is the value of U?

What is the value of W?

What is the value of V?

What is the value of Z?

What is the value of x?

What is the value of y?

Answers

Answer:

The value of U = 4

The value of W = -6

The value of V = 5

The value of Z = 1

The value of x = 3

The value of y =2

Step-by-step explanation:

Given:

20a³b³ – 24a⁵b² + 4a³b²

Solution:

Lets first factorize this expression:

20a³b³ – 24a⁵b² + 4a³b²

= −24a⁵b² + 20a³b³ +4a³b²

Taking 4a³b² common

= 4a³b² (−6a² + 5b + 1) ___ (1)

Now you can see this expression takes the form:

Ua^xb^y (Wa^2 + Vb+ z), where U > 0.

$Ua^(x)b^(y) (Wa^(2) + Vb + z)$

Now you can clearly see from (1)

The value of U is 4

The value of W is -6

The value of V is 5

The value of Z is 1

The value of x is 3

The value of y is 2

However if we take minus common from above equation:

20a³b³ – 24a⁵b² + 4a³b²

= −24a⁵b² + 20a³b³ +4a³b²

Taking 4a³b² common

= - 4a³b² (6a² - 5b - 1) ___ (1)

In this case the value of U is - 4, W is 6 , V is -5, Z is -1 , x is 3 and b is 2

How do I evaluate x+y=10

Answers

Hi there! Evaluate means to solve so we are going to solve x+y=10. Add both sides to -y, x+y+-y=10+-y=X=-y+10. Therefore, the answer is x=-y+10

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will total $60,239
. The variable costs will be
$10.50
per book. The publisher will sell the finished product to bookstores at a price of
$25.25
per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?

Answers

so the total=60239
so 10.5 per book
but -25.25 per book (since this is a negative cost or a gain)
so lets say they sell 1 book
it cost 10.5 and they gain 25.25 so they gain 14.75 total per book

so 14.75 times x books=60239
divide both sdies by 14.75
x=60239/14.75
then divide 60239 by 14.75 and get x=4084
they will need to sell 4084 books

assume the number of books X

the cost of the books = 60.239 + (10.50 X)
the sale amount = 25.25 * X

so 60.239 + 10.5 X = 25.25 X
60.239 = (25.25 - 10.5)X
60.239 = 14.75 X
X = 60.239 / 14.75

So X = 4.084
so the publisher needs to sell 4 books

Answers

Answer:

Second option is the right choice.

Step-by-step explanation:

Divide the second equation by -5 and you'll get the equation same as first equation.

$(5x)/(-5)-(20y)/(-5)=(-5)/(-5)\:\:\:\rightarrow \:\:\:-x+4y=1$

So, it has infinite many solutions.
