Answer:
-10%
Step-by-step explanation:
price elasticity of demand = % change in demand / % change in price
Here, the "price" changes from 15 to 45, so its percent change is ...
((new value)/(old value) -1) × 100%
= (45/15 -1) × 100%
= 200%
The % change in demand is given as -20%, so the price elasticity is ...
price elasticity of demand = (-20%)/(200%) = -0.10 = -10%
When you divide or multiply by a neg. number you must flip the sign, therefore t>-12 (the 3rd option)
Answer:
x = 1
y = -24
Step-by-step explanation:
8x + y = -16
-3x + y = -5
Subtract equation one from equation two
8x - -3x + y - y = -16 - - 5
8x + 3x = -16 + 5
11x = 11
Divide both sides by 11
11x/11 = 11/11
x = 1
Now substitute 1 for x in either of the equations to get y.
Using equation one, we have
8x + y = -16
8 x 1 + y = -16
8 + y = -16
Subtract 8 from both sides
8 - 8 + y = -16 - 8
y = -24
x = 1
y = -24
The answer would be yes. It takes 10 milliliters to make 1 centiliter.
Answer:
the answer is 12
Step-by-step explanation: x= -3 and y= - 4 x 3 is 12 - 3 + 3
