The absolute value function can be defined using piecewise notation. A(x)=x, x≥0 A(x)=−x, x<0 Use this notation to find the following values: 1. A(10)= 2. A(0)= 3. A(−3)= 4. A(3.14159)= 5. A(x)=7; x= and x=

the answer is 5/3x+7/5y+7

a

explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
