The train engine is <u>15 centimeters</u> long.
Step-by-step explanation:
The train car length doesn't matter. All you need to do is subtract 32 cm from the total length, 47 cm.

The train engine is 15cm long.
Answer:
Step-by-step explanation:
The y-intercept is super easy. The y-intercept exists when x = 0; therefore, the point given where x = 0 is found in (0, -15). That means that the y-intercept is -15. Easy enough. Now, the slope.
Since all these points are on the same line, using any 2 of them in the slope formula will get us the slope. I picked the first 2 points (1, -19) and (-4, 1):
![m=\frac{1-(-19)}{-4-1}=\frac{1+19}{-5}=\frac{20}{-5}= -4](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1-%28-19%29%7D%7B-4-1%7D%3D%5Cfrac%7B1%2B19%7D%7B-5%7D%3D%5Cfrac%7B20%7D%7B-5%7D%3D%20%20%20-4)
The y-intercept is -15 and the slope is -4
Answer:
y - 7 = -4 (x + 2)
Step-by-step explanation:
y - 7 = -4 (x + 2)
Well 3 times 52 weeks in a year. Equals 156. He will not have enough money by the end of the year.
3*52=156
The third one, divide 17 by 125
