Your Answer:
<em>B. 1/2n-3</em>
Explanation:
<em>One way to get half a number is to multiply it by 1/2.</em>
<em>The phrase "a number less than an other number" often indicates subtraction.</em>
Answer:
D. -5 <= x < 1
Step-by-step explanation:
the values under the square-root radical must not be negative, AND
the value of the denominator must not be 0 or negative
x+5 >=0 or x >= -5
and 1-x > 0 or x < 1
So the answer is -5 <= x < 1
Answer:
x= (y+2)/5
Step-by-step explanation:
Let f(x) = y
y = 5x -2
Adding 2 on both sides
y +2= 5x
Divinding by 5 in both sides
(y+2)/5 = x = f*(x)
Therefore,
f*() = (y+2)/5
.

The right answer is Option B.
Step-by-step explanation:
Given expression is;
5x√2 - 3√2 + x√2
We can add or subtract square roots only when the values inside the square root are same and the variables are also same.
In the given expression, variable x is same with √2, therefore, adding both the roots
6x√2 - 3√2 is equivalent to 5x√2 - 3√2 + x√2.
The right answer is Option B.

Answer:
x=7
Step-by-step explanation:
Starting with (x-2)² = 25
First, square root both sides to get rid of the square on the left. You'll get:
x-2 = 5
Add 2 to both sides to get x alone. You'll get:
x=7
Check your answer by filling in 7 for x:
(7-2)² = 25
(5)² = 25
25 = 25
