Find a negative real number such that the square of the sum of the number and 25 is equal to 36

"The square of the sum of the number and 25 is equal to 36" translates to 


Take square root of both sides:



Then subtract both sides by 25:



Hope this helps.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: the function g(x) has the greatest slope.

These are the multiples of 15 but what you are probably asking or what are the factors of 15
