5%
Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in price = (1.2/1) - 1 = 20%
Percentage change in quantity demanded = 450/500 - 1 = 10%
Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have

we have

The leading coefficient is negative, that means the parabola open downward
The zeros of the function are

Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
ASSUMPTION: Since we are talking about fractions it looks like you have to simplify it. Again, its still a guess so Id assume..
16/12 = 4/3.. So It should be <em>h = 2 </em>
Answer:
1 solution
no solution
infinitely many
1 solution
Step-by-step explanation:
1. 2.3x-7=-7
2.3x=0
x=0
2. 3x=5+3x
0x=5
x=5/0
That’s undefined
3. 40-4x=4(10-x)
40-4x=40-4x
They both are equal no matter what. So, infinitrly many
4. -7+x=-(x+7)
-7+x=-x-7
2x=0
x=0
1 solution I.e 0
