3. Which of the following can find 76 / 4
The correct answer is A. (2*38) / (2*2)
because you are factoring 76 and 4 and factoring out a 2 from both of them. You can later eliminate the 2s to divide 38 by 2 which is a lot easier.
4. is correct. Good job!
5. Which of the following equals 10
Your answer:
would not be correct because anything to the power of 0 is 1.
The correct answer is
Because anything to the power of 1 is itself.
6. What is
To add these fractions we need to have the same denominator and we do this by finding to LCD- the lowest commen denominator which is 8 in this case.
The we can easily add up these fractions
The correct answer is D. 8 1/8 ft

Answer:
y = 2x -33
Step-by-step explanation:
The line segment from the center (6, 4) to the given point (16, -1) is a radius of the circle. It is perpendicular to the tangent. Hence you need to write the equation of a line through point (16, -1) that is perpendicular to the line through that point and (6, 4).
The slope of the radius is ...
... ∆y/∆x = (-1-4)/(16-6) = -5/10 = -1/2
The slope of the tangent is the negative reciprocal of that, so is ...
... m = -1/(-1/2) = 2
In point-slope form, the tangent line through (16, -1) is
... y = m(x -h) +k
... y = 2(x -16) +(-1)
Simplifying, this is ...
... y = 2x -33
