28=8k+12-7k I HAVE 1 minute to answer this and show work QUICK PLEASE

k=16

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

28=8k+12−7k

28=8k+12+−7k

28=(8k+−7k)+(12)(Combine Like Terms)

28=k+12

28=k+12

Step 2: Flip the equation.

k+12=28

Step 3: Subtract 12 from both sides.

k+12−12=28−12

k=16

answer: 45

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)
