Answer:
4.2360679775
Step-by-step explanation:
Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

Answer:
The correct answer is x = -6.
Step-by-step explanation:
To solve this problem, we first must use the distributive property on the right side of the equation. This means that we can take the coefficient (the number located on the outside of the parentheses) and multiply it by the terms inside the parentheses. If performed correctly, we get the following:
-20 = -2(4 -x)
-20 = -2(4) - (-2)(x)
-20 = -8 + 2x
Next, we must begin to isolate the variable x on the right side of the equation. To do this, we should begin by adding 8 to both sides to cancel out the -8 on the right side of the equation.
-20 + 8 = -8 + 8 + 2x
-12 = 2x
Finally, we should divide both sides by 2 to get rid of the coefficient of x on the right side of the equation.
-12/2 = 2x/2
x = -6
Therefore, your answer is x = -6.
To check this answer, you could substitute this value back into the original equation and make sure that it produces a true statement.

Answer:
–√(7) must also be a root of f(x)
Step-by-step explanation:
Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:
f(x) = (x – 3)(x² – 7)
This is because we are dealing with √(7) and what brought about √(7) was x² = 7.
If this is the case, we know that x² = 7 will give
x = ±√(7)
Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).
Answer:
y = -5/3x - 3
Assuming this is a linear function
Step-by-step explanation:
1. Use (y2-y1)/(x2-x1) to find the slope of the equation, assuming it is a linear function.
(-3-2)/(0+3) = -5/3 <--- slope
2. The y-intercept is going to be the (0, -3) point, since the point is directly on the y-axis.
3. Put both of those values into the new equation
y = -5/3x - 3
