I think it's the first three.
-7.5 < -7
-4 < -3
-0.5 < -1
(those are the inequalities after i put each of the values for x in the original equation)
-7(x-4) = 63. Divide each side by -7.
x - 4 = -9. Add 4 to each side.
x = -5
Answer:
2x+4 or 4+2x
Step-by-step explanation:
Answer:
Step-by-step explanation
In the form ax^2+bx+c
a x c should equal two factors of b
However, in this equation
1 x 19 has no factors that = 10
so you must use the Quadratic Formula which is,
x = 
so the answer should be
x = 
x = 
x =
and x = 
Answer:
2/3
Step-by-step explanation:
2/5=0.4 and 4/7=0.571428
0.57<0.571428
---------------------------
2/3=0.6667
which is greater than or equal to 4/7
