Answer:
This above options makes the expression true.
- The negatives above can be distributed up as well, which happened in A.
- In E, when the negatives inside the bracket cancels out, the negative outside the brackets multiplies and makes the expression true.
- In B the expression turns positive, thus false same happens with C and D
Answer:
Below
Step-by-step explanation:
2x + 5 > -1
Treat the equality sign (ex. < >) as the costumary equal sign (=).
2x + 5 + (-5) > -1 + (-5) ---- -5 will cancel out the 5 on the left
2x/2 > -6/2 ------ divide by 2 to single out the x
x > -3
Remember to draw an open dot. Draw an arrow from -3 to the extreme right.
72 people stayed, because 96 ÷ 4 = 24, and 24 * 3 is 72.
Solve
-1(x-6)(x+8)
-1(x^2+8x-6x-48)
-1(x^2+2x-48)
-x^2-2x+48
Hope this helps :-)
