Answer:
10x + 30=140. Kegan has to mow his neighbors lawn 11 times.
Answer:
1. 0.333 No
2. 0.3 or 0.300 Yes
3. 0.667 No
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.
Answer:
321 R 3
Step-by-step explanation:
the quotient is 321 with a remainder of 3
you can check your work by doing 321 * 24 + 3 = 7,707
Answer:
Parallel lines
Step-by-step explanation:
Line BC:

Line AD:

Adding both equations, in this case, gives us the point at which the lines intersect:

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
