-2x + 5 < 7
-2x + 5 < 7
<u> -5 -5 </u> deduct 5 from both sides
-2x < 2
<u>÷ -2 ÷ -2 </u> divide both sides by negative 2. Because of the division
x > -1 using a negative number, the sign is then reversed.
from < it becomes >.
The value of x should be greater than -1. It can be 0, 1, 2, so on...
To check: Revert back to the original sign which is <.
x = 1
-2x + 5 < 7
-2(1) + 5 < 7
-2 + 5 < 7
3 < 7
Ok, hmm
possible ones are
starting with 8 or 9
adds to 13
8+5=13
9+4=13
thepossible numbers are 85 and 94
tens is 3 more than ones digit
8-5=3 true
9-4=5, not what we looking for
aswer is 85
You simplify the equation and then graph it duh, jk i have no clue i just need points
Circle Area = PI * radius^2
radius = 2.1
Circle Area = 3.14 * 2.1^2
Circle Area =
