The sum of two numbers is 87. The second number is 6 more than twice the first number. Find an equation that expresses this situation. You do not need to solve the equation

1/5^2 = 7.56/45

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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
