The excluded values of a rational expression are 2 and 5. Which of the following could be this expression?
LuckyWell [14K]

Answer:

You have not added the options, therefore, I cannot provide an exact answer. However, I can help you with the concept.

In any fraction, the denominator cannot be equal to zero because this would make the fraction undefined.

Excluded values are the values that would make the denominator equal to zero.

We are given that the excluded values are 2 and 5, this means that the factors of the denominator are (x-2) and (x-5)

This means that the denominator is x² - 7x + 10

Pick the fraction which has this denominator.

Hope this helps :)

A storekeeper increased the price of hats by 5%. Write an equation to calculate the increase of the total cost, c, when the pric
Naddik [55]

Answer:

c = 1.05p

Step-by-step explanation:

the price of the hat before the increase was 100%, after the increase it becomes 100 + 5% = 105%. Representing it as a decimal becomes 1.05p

Let illustrate with an example.

The price of a hat was $100, after the 5% increase. the cost of the hat becomes

100 + (0.05 x 100) = 105

To find the percentage increase

divide 105 by 100 and subtract 1

(105/100) - 1 = 1.05

Which equation of the solutions of x2 = -7x – 8
timama [110]

Answer:

x = 1, -5.56

Step-by-step explanation:

x^2 = -7x - 8

shift -7x and -8 to the other side . Remember when u shift minus changes into plus.

x^2 + 7x + 8 = 0

using quadratic equation formula

in quadratic equation one value comes positive and other comes in negative

a = 1  , b = 7 and c = 8

taking positive sign

x = (-b + \sqrt{b^2 - 4*a*c}) /2*a

x = (-7 + \sqrt{7^2 - 4*1*8} ) /2*1

x = (-7 + \sqrt{49 + 32} ) /2

x = (-7 + \sqrt{81} )/ 2

x = -7 + 9 / 2

x = 2/2

x = 1

taking negative sign

(-b - \sqrt{b^2 - 4*a*c} ) /2*a

x = (-7 - \sqrt{7^2 - 4*1*8} ) /2*1

x = (-7 - \sqrt{49 - 32} ) /2

x = -7 - \sqrt{17} / 2

x = -7 - 4.12 / 2

x = -11.12/2

x = -5.56

therefore x = 1 , - 5.56
