Alyssa is buying a pair of jeans for $39.99. The jeans are on sale at a 20% discount and the sales tax in Alyssa's city is 7%. What is the composite function that accurately represents this situation if the function to determine cost with tax is T(x) = 1.07x and the function to determine the sale price is S(x) = 0.80x?

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step-by-step explanation:

where is the question is there is a formula or is there not one

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
