In the diagram, BC is a radius of C. Determine whether AB is tangent to C. Explain your reasoning.
Whitepunk [10]

Answer:

No, AB is not tangent to C.

If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.

3²+6²=7²

9+36=49

45=49  Since this is false, it's not a right angle, and AB is not tangent.

Step-by-step explanation:

No, AB is not tangent to C.

If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.

3²+6²=7²

9+36=49

45=49  Since this is false, it's not a right angle, and AB is not tangent.

Evaluate 3 - (-1) + (-1) - 3.
lara [203]

Answer:

0

Step-by-step explanation:

3 <em><u>-</u></em> (<u><em>-</em></u>1) + (-1) -3 =

Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 <u><em>+</em></u> (<u><em>-</em></u>1) - 3 =

Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: <em><u>3 + 1 </u></em>- 1 - 3 =

Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: <em><u>4 - 1</u></em> - 3 =

Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: <em><u>3 - 3</u></em> =

Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0.

So the answer would be 0!

Write the equation of the line in fully simplified slope-intercept form.
iren2701 [21]
Y=Mx+b

Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)

Slope is -1/2
Yint = -8

So the equation is y=(-1/2)x - 8
