Answer:

Please look at the image.

I solved this by the information of 6 pages in 12 minutes which means 0.5 or half a page per minute.

Now you know you read half a page in a minute

5 pages in 10 minutes because:

10 × 0.5 = 5

8.5 pages in 17 minutes because:

17 × 0.5 = 8.5

Mice21 [21]

Answer:

Domain of the function represented in the graph is given by he inequality $2 \leq x \leq 10$ .

Step-by-step explanation:

We are given the following information in the question:

The graph shows the plot for quantities of green and yellow paints used for each mix.
The x-axis shows the quantity of yellow paint used in millimeters.
The y-axis shows the quantity of green paint used in millimeters.

We have to find a domain for the function shown in the graph.

Domain of a function is basically the set of all values of x for which the function is defined.

If we observe the graph, particularly the x-axis, the plot starts from value 2 and goes upto 10.

So x can take values from 2 to 10.

This can be represented with the help of inequality:

$2 \leq x \leq 10$

Hence, domain of the function represented in the graph is given by he inequality $2 \leq x \leq 10$ .

What is the largest of three consecutive positive integers if the product of the two smallest is equal to 2 more than 8 times th

pogonyaev

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

n(n + 1) = 8(n + 2) + 2 ust the distributive property

n² + n = 8n + 16 + 2

n² + n = 8n + 18 subtract 8n from both sides

n² - 7n = 18 subtract 18 from both sides

n² - 7n - 18 = 0

n² - 9n + 2n - 18 = 0

n(n - 9) + 2(n - 9) = 0

(n - 9)(n + 2) = 0 ⇔ n - 9 = 0 or n + 2 =0

n - 9 = 0 add 9 to both sides

n = 9

n + 2 = 0 subtract 2 from both sides

n = -2 < 0

n + 2 = 9 + 2 = 11

A^3+a+a^2+1 2a^2+2ab+ab^2+b^3

Vikentia [17]

$\frac{a^3+a+a^2+1}{a^3+a^2+ab^2+b^2} \cdot \frac{2a^2+2ab+ab^2+b^3}{a^3+a+a^2b+b} =\frac{a(a^2+1)+1(a^2+1)}{a^2(a+1)+b^2(a+1)} \cdot \frac{2a(a+b)+b^2(a+b)}{a(a^2+1)+b(a^2+1)} =\\\\=\frac{(a^2+1)(a+1)}{(a+1)(a^2+b^2)} \cdot \frac{(a+b)(2a+b^2)}{(a^2+1)(a+b)} = \frac{2a+b^2}{a^2+b^2}$
