Answer:
After 4 hours
Step-by-step explanation:
4h = 2(2) + 6(h - 2)
4h = 4 + 6h - 12
4h = 6h - 8
2h = 8
h = 4
Answer:
z = 5
x = 0
x = 1
Step-by-step explanation:
(z - 5)x^2 - (z - 5)x = 0 Take out z - 5 as a common factor
(z - 5)(x^2 - x) Take out x as a common factor
(z - 5)(x)(x - 1) Any one of these could equal 0. There are 3 solutons.
z - 5 = 0 Add 5 to both sides
z - 5 + 5 = 0 + 5
z = 5
===============
x = 0
===============
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1

Answer:
2
Step-by-step explanation:
Given the system of equations:
Comparing 
with the general standard equation of a circle 
.
The first equation is an <u>equation of a circle centred</u> at (0,0) with a Radius of 3.
The second equation 9x+2y=16 is a <u>straight line equation.</u>
A straight line can only intersect a circle at a maximum of 2 points.
Therefore the greatest possible number of solutions to the equations in the system is 2.
Answer: - .35 or 13.5 depending on how the equation is written.
Step-by-step explanation:
-45 = (117+12)x
-45 = (129)x
-45/129 = x
roughly = - .35
If that's not it we can do:
-45 = 117+12(x)
-162 = 12x
x = 13.5
