Answer:
A. 40.18
B. 42.80
Step-by-step explanation:
A. To find the discount price of an item multiply the price by the percentage you pay. Its discounted 20% meaning you pay 80%. Then the price of the coat is 0.8(50.22) = 40.18.
B. The sale price of a shirt is 25.68. The original price as reduced by 3/5. The original price is equal to 25.68 = 3/5x. Solve for x by multiplying by the reciprocal. 25.68 ( 5/3) = x. 42.8 = x.
Using the data below, what is the equation for the line of best fit? Remember, put your answer in y = ax + b form and round any decimals to two places.
i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.
We can thus write our values as ordered pairs
(0, 0) - This ordered pair is also referred to as the origin
(1, 2.5)
(2, 5)
(3, 7.5)
These ordered pairs can then be plotted into a graph.
