Answer:
x = 7/4 = 1.75
Step-by-step explanation:
Hello - so you don't seem to have shown what the calculator screen displays, however I can assume it will show a graph of the two lines, and their intersection point. The x-co-ordinate of this intersection point is the solution to the equation.
As I can't see the calculator, I will also show you how to work out the solution for x:
3x - 1 = 6 -x
4x -1 = 6
4x = 7
x = 7/4 = 1.75
Answer:
a. vertical
b. horizontal
c. horizontal
d. vertical
Step-by-step explanation:
if the x coordinate changes it's horizontal and if the y coordinate changes it's vertical
Answer: The first answer choice
Step-by-step explanation:
In the first answer choice, the distance increases for two units, then decreases for three units. The distance then increased for 4 units, stayed level for 3 units, and then decrease slowly for 6 units. The graph exactly follows this trend.
The second answer is <em>immediately wrong</em> because it relates the distance between the car and the concert venue. <em>It never mentioned that the car moved, and the venue obviously can't move</em>.
The third answer says that after the first increase/decrease, Tyler went to go text his friends. However, <em>the graph does not show a flat area after the first increase/decrease</em>.
The fourth answer, like the second answer is immediately wrong because <em>homes and schools can't move</em>.
This is my first response, so I hope it was helpful. :D
