Answer:
The price dropped by $5.45.
Step-by-step explanation:
Initial price = $50.00
Less 10 % = -5.00
1st sale price = 45.00
Less 10% = -4.50
2nd sale price = 40.50
Plus 10 % = +4.05
Final price = $44.55
Change in price = final - initial
= 44.55 - 50.00
= -$5.45
The price dropped by $5.45.
First find the slope:
The slopes of perpendicular lines must multiply to -1.
-9m = -1 ----> m = 1/9
Next, use point-slope form:
y - y1 = m(x-x1) , where given point (0,5) is (x1,y1)
y - 5 = (1/9)(x - 0)
Finally, solve for y to put it in slope-intercept form:
y = (1/9)x + 5
Distance = 150 miles
Consumption of gas = 25 miles / gallon
Price = $3 / gallon
Calculation is done as follows:
Total cost = $3 / gallon (150 miles / (25 miles/gallon)) = $18
Answer:
12
Step-by-step explanation:
normally multiplying -2 and -6 would be -12 but
when || is used the negative number turn positive
so the answer is 12
