What single decimal multiplier would you use to decrease by 12% followed by a 5% decrease?

The single decimal multiplier is 0.836

Step-by-step explanation:

In this question, we are concerned with using a single decimal multiplier to denote a 12% decrease followed by a 5% decrease.

Let the number we want to decrease be x

A 12%(12/100 = 0.12) decrease means x - 0.12x =  0.88x

Now, we want to follow this up by a 5% decrease(5% = 5/100 = 0.05)

5% decrese of 0.88x is 0.88x - 0.05(0.88x)

= 0.88x - 0.044x = 0.836x

Thus, the single decimal multiplier that reflects a 12% decrease followed by a 5% decrease is 0.836

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
