Yes，y＝2x＋7 is a function
because x is argument，and it has x and y，it is a primary function
If the shoes cost 95 dollars and are at a 30% discount then we know that the shoes cost 70% of its original price. we would write this as 95 x .7 which is 66.50 dollars. The tax would up the price. To do this we need to add a 1 to whatever the tax percentage is. this would then be written as 1.07 x 66.50 and the answer is 71.155. since you can’t pay that amount you have to round up to the near test hundredth. Since the number in the thousandth spot is 5, we round up making your final price 71.16 dollars.
The coefficients are 7, 3, and 5. Coefficient just means the number before the variable
