First, transpose the constants to the right side just like an ordinary equation, but leave the inequality sign as it is. That becomes
x - 72 > -96
x > -96 + 72
x > -24
Thus, just check among the choices which are greater than -24. The answers would be D and E.
Answer:
4) About 96% of newborn girls were the same length as Alexandria.
Step-by-step explanation:
Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
Answer:
x=12, y=4. (12, 4).
Step-by-step explanation:
x-y=8
x/y=3
--------
x=y+8
(y+8)/y=3
y+8=3y
8=3y-y
8=2y
y=8/2
y=4
x-4=8
x=8+4
x=12
The answer would be 59.
Because the first point is (0, 59) I am positive on this answer. Hope this helps!
