Answer:

y = 1/2x -2

Step-by-step explanation:

The given equation is in slope-intercept form, so you recognize its slope is -2. The perpendicular line will have a slope that is the opposite reciprocal of that, so is -1/-2 = 1/2.

The y-intercept can be found from ...

b = y -mx . . . . . for line of slope m through point (x, y)

b = -1 -(1/2)(2) = -1 -1 = -2

Then the slope-intercept equation of the perpendicular line is ...

y = 1/2x -2

A clerk is marking up merchandise 34%. The original price of an item is $455. What will be the retail price?

Galina-37 [17]

Take the orginal price and multiply it by 1.34.
455 * 1.34 = $609.70 in retail.

The longer way would be to take 34% of 455 and then add it to 455.

For the 9 times table, in the answer section, order the answers 9,1,2,3,4,5,6,7,8,9 and then backwards order 0,1,2,3,4,5,6,7,8. This is a very easy way to understand the 9 times table.
