Answer:

$y=-55x+570$

Step-by-step explanation:

The correct question is

Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.

Let y represent the number of pages left to read after x hours.

Complete the equation for the relationship between the number of pages left and number of hours.

Let

x -----> the time in hours

y ----> the number of pages left to read

we know that

The linear equation in point-slope form is equal to

$y-y1=m(x-x1)$

In this problem we have

$m=-55\frac{pages}{hour}$ ----> is negative because the linear function is decreasing

$point\ (4,350)$

substitute

$y-350=-55(x-4)$

$y-350=-55x+220$

$y=-55x+220+350$

$y=-55x+570$

Fuaad solved an absolute value inequality and expressed the solution as . What is another way to show Fuaad’s solution? For all

Ira Lisetskai [31]

Answer:

{x I - 12 < x < 7}

Step-by-step explanation:

Fuaad solved an absolute value inequality and expressed the solution as - 12 < x < 7.

So, the value of x lies between - 12 and 7 but not including - 12 and 7.

Option C will give another way to show Fuaad's solution.

It is {x I - 12 < x < 7}, which means x is a variable which belongs with in the interval (- 12, 7). (Answer)

What is 4 3/4 + 7/8 showing all work

Mekhanik [1.2K]

$4 \frac{3}{4} + \frac{7}{8}$

Convert mixed numbers to improper fractions

$= \frac{19}{4} + \frac{7}{8}$

Find de LCD for 4 and 8 :

Factor each denominator into its primes:

$4 = 2^2
$

$8 = 2^3$

Find the least common denominator $2^3 = 8$

Adjust fractions based on the LCD :

$\frac{19*2}{8} + \frac{7}{8}$

Since the denominators are equal , combine the fractions:

$\frac{2*19+7}{8}$

$\frac{38+7}{8}$

$= \frac{45}{8}$

Therefore:

Convert improper fractions to mixed numbers

$= 5 \frac{5}{8}$

hope this helps!

Simplify and solve for d. 1/6d+2/3=1/4(d-2)

Dvinal [7]

1/6d + 2/3 = 1/4(d - 2)
1/6d + 2/3 = 1/4d -1/2
2/12d + 4/6 = 3/12d -3/6
4/6 = 1/12d - 3/6
7/6 = 1/12d
7/6 x 12/1 = d
84/6 = d
14 = d

So d = 14.

Hope I helped.. ^^
