Which equations represent functions? 2x+3y=10. 4x=16. 2x - 3 =14. 3y=18. 14.6=2x

Vlad [161]

2x + 3y = 10 -> y = -2/3x + 10/3 it's a function

4x = 16 -> x =4 it's not a function

2x - 3 = 14 -> x = 8.5 it's not a function

3y = 18 -> y = 6 it's a function

2x = 6 -> x = 3 it's not a function

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48. The height of the model train is 102 millil

alekssr [168]

Answer: The actual height of train = 4.896 meters.

Step-by-step explanation:

Since we have given that

Lina has a scale model of a modern train

Model is created at a scale is given by

1:48

Height of the model train = 102 millimeters

We need to find the actual height of the train.

Since there is direct variation between model and actual height of the train.

According to question,

$\frac{1}{48}=\frac{102}{x}\\\\x=102\times 48\\\\x=4896\ millimeters\\\\x=4.896\ m$

Hence, the actual height of train = 4.896 meters.
