a store is having a 20% off sale. the sale price of an item with price p is p – 0.2p. what is an equivalent expression?

The equivalent expression to the sale price of an item is 0.8p, where p is the price of the item.

Solution:

Given that store is having a 20% off sale

The sale price of an item with price p is p – 0.2p

To find: Equivalent expression

Given expression is:

Sale price = p - 0.2p

Where "p" is the price of item

Let us simplify the given expression for sale price to find the equivalent expression

Sale price = p - 0.2p

Factor out p from above expression

Sale price = p( 1 - 0.2)

Sale price = p(0.8)

Thus, sale price = 0.8p

Thus the equivalent expression is 0.8p

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
