Answer:
B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
Answer:
a) 49
b) 100 (I'm assuming that the 2 was supposed to be a square)
Step-by-step explanation:
Substitute the value in for x (the value being 7):
7² = 49
(7 + 3)² = (10)² = 100
Answer:

Step-by-step explanation:
First lets fill in the variables

Now solve
3 - 9 = -6
2 - -1 = 3
-6/3 = -2
