Answer:
1 is x=12
2 is x= 1/5
Step-by-step explanation:
For equation number 1 you just add 10 and 2, which is 12.
For equation number 2 you divide 2 by 10 and simplify it to 1/5. So x = 1/5
Step-by-step explanation:
f(2)= -2×2×2+ 6×2 -7
=-8+12-7
=-3
Answer:
y>5/6
Step-by-step explanation:
5y+3>-7y+13
5y+7y>13-3
12y/12>10/12
y>5/6
This is an inequality, which shows where the variable y does or does not exist
from this we can say
y: (-infinity,5/6) (5/6, infinity]
or, y does not exist from (-infinity,5/6)
and does exist from (5/6, infinity]
