Brainlist for correct answer and 25 points for answering! Write the equation of a line that is perpendicular to y=0.25x-7 and th
MAXImum [283]
I’m pretty sure it’s y=-4x-16

Because the standard slope equation is y=mx+b and in perpendicular lines the slope is opposite of the slope on a parallel line. 0.25 is equal to 1/4 and the opposite of 1/4 is 4/1 but you also make it negative so it’s -4. So we have y=-4x+b and you plug in the coordinates and solve [8=-4(-6)+b and -4*-6=24 so you rewrite it as 8=24+b and 8-24=-16 and -16=b] so you plug in b and the equation is y=-4x-16

Hope this helped

Model with mathematics. Hamid has read 60 pages of the book
vagabundo [1.1K]

Answer:

Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Step-by-step explanation:

Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:

375/45 = X

8.3333 = X

0.333 x 60 = 20

Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Simplify the expression.
netineya [11]

Answer:

-6m^2 *n^2

Step-by-step explanation:

formula: (m^x)/(m^y)= m^(x-y)

apply formula for (4m^2)/(2m^-3)

=(4m^(2--3)/(2)

=4m^5/2

divide 4/2

=2m^5

next part 3n^5/(-mn)^3

3n^5/(-mn)^3

expand

=3n^5/ (-m^3*n^3)

=3n^(5-3)/ -m^3

=3n^2/ -m^3

both parts:

(2m^5* 3n^2)/ -m^3

= -(2m^5* 3n^2)/ m^3

= -(2m^(5-3)* 3n^2)/ 1

= -(2m^2* 3n^2)

= -(6m^2*n^2)

= -6m^2 *n^2
