Answer:
$45.05
Step-by-step explanation:
Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50. Nya has to pay 6% sales tax on this $42.50. Thus, the final amount due is
(1.00 + 0.06)($2.50) = $45.05
To solve this, simply switch the X and y variables within one equation, and upon doing so, see and check if it equals to the other equation.
f(X) = -X + 4/5
Y = -X + 4/5
X = (-Y+4)/5
5X = -Y + 4
-Y = 5X - 4
Y = -5x + 4
Yes, by looking at the second equation it is an inverse of the first one.
A = 11, b = 7
You just needed to multiply the terms together
Answer:
Start at 80(y) go to 10:00(x)
Step-by-step explanation:
Joey's house is the same distance to his friend's house as his friend's house is to his. This means that if the travel at the same rate the rate of change (slope) will be the same. However because the friend is going the opposite direction of joey the rate of change (slope) will have the opposite sign (negative vs positive, down vs up)
