Christian claims he found the solution of the following equation. His work is
shown below. There is a mistake in Christian's work.
In the space below, be sure to answer all of the parts of this question.
Part A) Describe what error Christian made.
Part B) Solve the equation correctly. YOU MUST SHOW ALL OF THE
STEPS.
Part C) What is the correct solution of this equation?

X - 2(x - 6) = 3x + 12
X - 2x - 12 = 3x + 12
- 1x - 12 = 3x + 12
+ 1x
- 12 = 4x + 12
-12
- 12
-24 = 4x

answer: it is 1: 47 pm

the bottom of the spinner is not flat.

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

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)
