Cho is making a rectangular garden, where the length is x feet and the width is 4x – 1 feet. He wants to add garden stones around
the perimeter of the garden once he is done. If the garden is 4 feet
long, how many feet will Cho need to cover with garden stones?

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
