When you have -(-2) it equals +2 and the same goes for any other number. When you have +(-2) it equals -2 and the same goes for any other number. Hope this helps!
Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
Answer:
z = - 170
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 19
m = 
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (- 6, z)
m = 
= 
= 19 ( multiply both sides by - 9 )
z- 1 = - 171 ( add 1 to both sides )
z = - 170
The two equations are above. It is better to go to Ice Plex for skates under five hours and Skate World for skates over five hours.
Answer:
Susie must be willing to pay $35 for it to be efficient for government to produce the third unit
Step-by-step explanation:
We have given marginal cost MC = $100
For government it is efficient to provide public good when Marginal benefit from good = MC of good.
MC = $ 100 so MB from all people must be equal to 100
MB = 40 + 25 + x
MC = MB
100 = 40 + 25 + x
x = 35
So Susie must be willing to pay $35 for it to be efficient for government to produce the third unit
So option (a) is correct answer
