Answer:
x = 10/7 or x = -10/7
Step-by-step explanation:
By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides
From what we have here, the coefficient of the x term is 0
Thus, we have it that;
0 = 100 - 49x^2
We can proceed to use the difference of two squares here;
Whereby;
a^2 - b^2 = (a-b)(a + b)
0 = (10-7x)(10+7x)
10 - 7x = 0 or 10 + 7x = 0
7x = 10 or 7x = -10
x = 10/7 or x = -10/7
Answer:
Step-by-step explanation:
You have the following functions:
Therefore 
indicates that you must divide both functions, as you can see below:
Simplify it. Therefore, you obtain:
Answer:
Option A, x ≥ -2
Step-by-step explanation:
<u>Since the line is not dotted, that means that -2 is included. Also, since the darkened part is toward positive infinity, that means that it is ≥.</u>
<u />
So, it is <em>x ≥ -2</em>
Answer: Option A, x ≥ -2
Seven eighth, 7 over 8, 7/8, 0.875,
