Y=-2.9x+120
Step-by-step explanation:
The most simple way to solve is plug any x value into each equation and see if it works
Answer:
15
Step-by-step explanation:
If you replace each answer choice with the varibale, (x) then 15 would be the only choice that fits properly.
Equation:
20-x = 35-(2x)
when replacing 15 with x this is your new equation...
20-15 = 35-(2x15)
5 = 35-30
5=5

Answer:
rational
Step-by-step explanation:
Answer: 1/(4a^2) + 1/(3a) + 1/9
Step-by-step explanation:
= (1/2a + 1/3)(1/2a + 1/3)
= 1/(4a^2) + 1/(6a) + 1/(6a) + 1/9
= 1/(4a^2) + 2/(6a) + 1/9
= 1/(4a^2) + 1/(3a) + 1/9
