Answer:

450 - 30x

Step-by-step explanation:

Lourdes reads 30 pages in one day

Total pages in book = 450

The number of days is x.

Lourdes reads in x days = number of pages read in one day x number of days

                                        = 30 x

Number of pages left after x days = 450 - 30x

Thus, the number of pages left after x days is 450 - 30 x .

They read 30 pages a day, so you need to multiple 30 by the number of days they read, which would be 30x.

You would then need to subtract that total from the total number of pages in the book.

Let Y be the number of pages they have left to read.

The equation would become y = 450 - 30x

A halloween assorted bag of candy contains 4 Snickers, 2 packages of M&M's, & 3 Butterfingers. What is the probability o
a_sh-v [17]

Answer:

2/27

Step-by-step explanation:

In the question we have:

4 snickers

2 packages of M&M's

3 Butterfingers.

Total number of candies in the Halloween bag = 9

Probability of selecting some M&M's and putting them back = 2/9

Probability of selecting a Butter finger = 3/9

Therefore, the probability of selecting some M&M's, putting them back, and then selecting a Butterfinger =

Probability of selecting some M&M's and putting them back × Probability of selecting a Butter finger

2/9 × 3/9

= 6/ 81

= 2/27

What are the approximate values of the non-integral roots of the polynomial equation?
irga5000 [103]

Answer:

-4, -2, -3-2i, -3+2i

Step-by-step explanation:

The of the polynomial equation are those values of x, for which f(x)=0.

Consider equation

f(x)=0\\ \\(x^2+6x+8)(x^2+6x+13)=0

By zero product property,

x^2+6x+8=0\ \text{or}\ x^2+6x+13=0

Solve each equation:

1. x^2+6x+8=0

D=6^2-4\cdot 8=36-32=4\\ \\x_{1,2}=\dfrac{-6\pm \sqrt{4}}{2}=\dfrac{-6\pm 2}{2}=-4,\ -2

2. x^2+6x+13=0

D=6^2-4\cdot 13=36-52=-16=16i^2\\ \\x_{1,2}=\dfrac{-6\pm \sqrt{16i^2}}{2}=\dfrac{-6\pm 4i}{2}=-3-2i,\ -3+2i

In the function ƒ(x) = x2 + x + 1, which of the following represents the output value? Select one or more: A. f(x) B. x2 C. x D.
kakasveta [241]

Answer:

The correct answer is f(x)

Step-by-step explanation:

The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:

Let be x= 2

Then f(2)= 4+2+1=7

Therefore the output is f(2) which is equal to 7.
