Answer:
2/5 m or 4 dm
Step-by-step explanation:
The fraction 4/10 can be reduced by removing a factor of 2 from numerator and denominator. The length could be expressed as 2/5 m.
The metric system has unit prefixes that make it easy to choose appropriate units for almost any measurement. Apparently Christina wants to use 1/10 m as her unit of measurement. That length is also called a "decimeter." So, Christina's measurement could be expressed in very simple form as 4 dm.
_____
A decimeter is not a particularly common unit in everyday use, though it is reasonably useful for many purposes.* More conventionally, lengths in that range are expressed in centimeters, so Christina's measurement could also be described as 40 cm.
____
* I like units of decimeters for volume calculations, because a cubic decimeter is 1 liter.
Answer:
I think your problem didn't copy correctly because you didn't provide a function. if you could provide it to me I would be glad to help and give you the answer.
I also do exams and quizzes if your interested
Answer:
y = +3/2x + 12
Step-by-step explanation:
get slope
get midpoint
get b
1.
(-7,8) and (-1,4)
get slope
(y₂ - y₁) / (x₂ - x₁)
slope is -2/3
perpendicular slope is the negative reciprocal :
+3/2
y=mx + b
y=+3/2x + b
get midpoint :
(x₁ + x₂)/2, (y₁ + y₂)/2
(-4,6)
get b
y=mx + b
6=+3/2(-4) + b
6= -6+ b
b = 12
y = +3/2x + 12
