I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
y = \sqrt{x + 11}
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.

Find the equation of the line in slope-intercept form containing the points (4,6) and (9,16).
inna [77]

Hello!

Slope-intercept form is y = mx + b. In this form, m is the slope and y is the y-intercept.

To find the slope, we need to use the slope formula. The slope formula is: \frac{y_{2}-y_{1} }{x_{2}-x_{1}}. We can assign the point (4, 6) to x_{1} and y_{1} and (9, 16) to x_{2} and y_{2}.

Now, we can find the slope: \frac{16-6}{9-4} = \frac{10}{5} = 2

Next, we can find the y-intercept by substituting a point into the slope-intercept form with the slope as 2.

y = 2x + b (substitute a given point)

6 = 2(4) + b (simplify)

6 = 8 + b (subtract 8 from both sides)

-2 = b

Therefore, the equation of the line is y = 2x - 2.

Why do you subtract exponents when dividing powers with the same base?
enyata [817]

Because the factors in the numerator cancel with the factors in the denominator. Consider this example:

\dfrac{6^7}{6^4} = \dfrac{6\times6\times6\times6\times6\times6\times6}{6\times6\times6\times6} = 6\times6\times6 = 6^3 = 6^{7-4}

All of the 6's in the denominator canceled with the 6's in the numerator, and only 3 6's "survived". The opposite can also happen, if there are more terms in the denominator:

\dfrac{2^2}{2^4} = \dfrac{2\times 2}{2\times 2\times 2 \times 2} = \dfrac{1}{2^2} = 2^{-2} = 2^{2-4}

So, everything is coherent

When I did it I didn't get any of the answer choices so I know i'm Incorrect please help me find the correct answer
Viktor [21]

Answer:

17 units

Step-by-step explanation:

P to Q = (-2,2) to (5,2) =  is 7 units  

The Q to R  = (5,2) to (5,-5) is 7 units

Then R so S =  (5,-5) to (8,-5) is 3 units

7+7+3 = 17 units
