Arectangular plot of land has the length of 4/7 mile and a width of 3/8 mile. what is the area of this plot?

3/14 of a mile

Step-by-step explanation:

It is asking for area.  The area of a rectangle is base times height

A = bh

the length can be either the base or the height.  It won't matter for this question.  Same goes for the width.  Lets use 4/7 as the base, and 3/8 as the height.  

So

A = (4/7)(3/8)

*When multiplying fractions, multiply the numerators together, and multiply the denominators together, then simplify the resulting fraction.

A = (4/7)(3/8)     becomes  

A = 12/56           which reduces to

A = 3/14          (both 12 and 56 are divisible by 4)

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
