Nikaese was 57 cm long at birth. He is 7 years old now and is 1.42 m tall. How much has he grown in height in the past 7 years? Express your answer in metres.

0.85m grown in 7 years

Step-by-step explanation:

cm - > m

57 cm -> 0.57m

1.42 - 0.57 = 0.85m grown in 7 years

He has grown 85 cm. Or 0.85 meters

Step-by-step explanation:

If you multiply the 1.42 meters by 100, change the unit to centimeters. SO thats 142 cm. Then you subtract it from the 57 centimeters he was at birth you get... 85 centimeters or 0.85 meters.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
