Is the line y=3x-7 parallel or perpendicular to 3x+9y=
9?Explain your answer

yes, perpendicular

Step-by-step explanation:

perpendicular lines on a graph has opposite reciprocal slope

3x+9y=9 ( put the equation in the  slope intercept form y=mx+b

9y=-3x+9

y=-3x/9+9

the slope of the first question is 3

the slope of the second equation is -1/3 x

yes the two lines are perpendicular

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
