They are all prime numbers,because you can only multiply them by 1.
Gradient of a line times the gradient of a line that is perpendicular to it is-1
M1M2=-1
2/3 times M2=-1
M2=-1 times 3/2
The gradient is =-3/2
Option D
Function used to determine the profit the theater group earns from selling "x" tickets is f(x) = 12.50x - 150
<h3><u>
Solution:</u></h3>
Given that a theater group charges $12.50 per ticket for its opening play of the season
Also given that Production costs for the play are $150
To find: function used to determine the profit the theater group earns from selling "x" tickets
So "x" represents the number of tickets sold
Cost per ticket = $ 12.50


Production costs = 150
Then the profit the theater group earns from selling "x" tickets is:
<em>Profit earned from selling "x" tickets = cost of "x" tickets - production cost</em>
Let f(x) denotes profit earned from selling "x" tickets
f(x) = 12.50x - 150
Thus option D is correct
To find this simply do 5!, or 5×4×3×2×1. That equals 120,
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0] solving: [-14 8 0] [-3 0 5]
[42+0+70 -24+0+40 0+0+0]
[-14 8 0] * [-3 0 5] = [112 0 -30] = [112 16 0]
[112 16 0]*[6 2 1]
[112 0 -30]* [6 2 1] = [1008 114 0] [672+224+112 96+32+16 +0]
=[1008 114 0].
