Factor: 25x^(2)-64y^(2)

(5x-8y)(5x+8y)

Step-by-step explanation:

25x^2 - 64y^2

= (5x)^2 - (8y)^2

= (5x-8y)(5x+8y) {a^2 - b^2 = (a-b)(a+b)}

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

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
