1. the expression 0.08x+(x−200) models the final price of a computer with an instant rebate in a state that charges a sales tax.

enter the expression in the box that represents the amount of tax that is paid on the computer.

2.the expression 937(1+x) gives the markup price of a computer, where x is the percent of the markup written in decimal form.

which part of the expression represents the percent, in decimal form, of the initial price that is being paid?

enter your answer in the box.

#1) 0.08x; #2) (1+x)

Step-by-step explanation:

#1) 0.08 is read as 8 hundredths.  This can also be written as 8/100.  Percent means out of 100; this means 8/100 is 8%.  This means 0.08x is taking 8% of the original amount; this would represent the sales tax that is paid.

#2) In this problem, x is the percent of markup written in decimal form.  This means that adding 1 to this number gives us 100% plus the percent of markup.  This will give us the percentage of the original price that was paid, since we are paying 100% of the original price plus the markup.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
