Answer:
x+7 ≤ 20
Just take it step by step:
seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.
it then says it's equal to at most 20.
This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
x+7≤ 20
≤ -this symbol means less than or equal to
Step-by-step explanation:
Answer:
x>8 and x<6
Step-by-step explanation:
well first the values of x-7 have to be greater than 1 or, less than -1
because if x-7=-2 then |-2|=2>1 satisfying the equation
so we have
![x-7>1\\\\x-7+7>1+7\\\\x>8](https://tex.z-dn.net/?f=x-7%3E1%5C%5C%5C%5Cx-7%2B7%3E1%2B7%5C%5C%5C%5Cx%3E8)
and we have
![x-7](https://tex.z-dn.net/?f=x-7%3C-1%5C%5C%5C%5Cx-7%2B7%3C-1%2B7%5C%5C%5C%5Cx%3C6)
to graph it it goes from (-∞,6)∪(8,∞)

and then mutupy them together
Answer:
2x^2-2x
Step by Step Explanation:
The 2 x^2 come together to form 2x^2 and since there is no other number that has x but no ^2 -2x stays the same.
D=25m+50
D=(25)(8)+50
D=200+50
D=250
There will be $250 after 8 months.
