1) AB/AC = 1/2
(3x-4)/(2x+12) =1/2
2(3x-4) = 1(2x+12)
6x - 8 = 2x +12
4x = 20 And x = 5

2) Prove AC/BC 2/3 ===== (2x+12)/(7x-2) = 2/3;
Plug in x = 5:

(10+12)/(35-2) = 22/33. Simplify numerator & denominator by 11

(2)(11)/(3)(11) = 2/3

The graph shows Kelly traveling from home to her grandmother's house: A graph is shown with the title Kelly's drive. The x-axis

Luden [163]

Answer:

The correct option is: B

Step-by-step explanation:

The x-axis is labeled Time driving, and the y-axis is labeled Distance driven.

Segment B is a horizontal line from x equals 0.5 until 1.75.

So, the value of $y$ is constant in the interval $x=0.5$ to $x=1.75$ is 0.

Thus, the distance traveled in the time interval 0.5 to 1.75 will be 0, which means the car was in the same position in that time interval.

So, the interval B on the graph indicates she is stuck in a traffic jam.
