Answer:
The cost of one unit of electricity is $0.185
Step-by-step explanation:
Amount charged = $120.99
Units of electricity used = 654
The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.
So that,
cost of one unit of electricity = 
= 0.185
cost of one unit of electricity = $0.185
This implies that the cost of electricity used is charged at $0.185 per unit.
Thus for 654 units of electricity used, the cost would be;
654 x $0.185 = $120.99
Answer:
x= √2 - 2 + √5-4√2, √2-2 - √5-4 √2
Slope intercept form is y = mx+ b
So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!
Let's do it!
- add 3x to the right side of the equation
<u>5y - 3x + 20 = 0</u>
<u>5y + 20 = 3x </u>
- move 20 to the right side
<u>5y = 3x - 20 </u>
- Divide both sides of the equation by 5
y = 3/5x - 4
This is our answer!

If it has real zeros at x=3 and 7, the factors of f(x) are:
(x-3)(x-7) so f(x) is
f(x)=x^2-10x+21
Answer: 9) K ||| 10) H
9) This is because at first the probability is 5/14 but once we take one red out we have to account for that so the probability the second time will be 4/13
10) Ming=2/5 Tyrel=5/8
If ming plays 200 they can expect to win (2/5 x 200) = 80
If tyrel plays 200 they can expect to win (5/8 x 200) = 125
To find how how many more tyrel will win than ming just do 125 - 80 = 45
Hope this helps :)
