A line passes through the point (-8, 4) and has a slope of - 5/4.

Answer:

y-4=m(x+8)

Step-by-step explanation:

point slope form is y-y1=m(x-x1) where y1 is the y in the point the line passes through, and x1 is the x in the point the line passes through.

So, you can put in (-8,4) in as I did.

Also, since the x in the point the line passes through is a negative, and two negatives make a positive, that's why the x-x1 part changes into x+8

Hope my explanation makes sense!

Answer:

Point-slope equation is

y-y1 = m(x-x1)

m is a slope, m=5/4

y1 = -5, x1 = 8

Point-slope equation is

y+5 = 5/4(x - 8).

Step-by-step explanation:

Answer:

  C.  {-1, 5, 8}

Step-by-step explanation:

Use each of the domain values in the function to see what the corresponding range value is.

  f(-1) = 5 -3(-1) = 8

  f(0) = 5 -3(0) = 5

  f(2) = 5 -3(2) = -1

The range is the set of numbers {-1, 5, 8}.

_____

<em>Additional comment</em>

The values in a set are generally listed lowest to highest. The coefficient of x in the equation for f(x) is negative, meaning the lowest range value will correspond to the highest domain value. If you start by finding f(2) = -1, you immediately eliminate all answer choices except B and C.

Those choices differ only in the middle value, so you can tell which is correct by evaluating f(x) for the middle domain value: f(0) = 5. Only one answer choice has both -1 and 5 in the set.

(There are two answers here: how you work the problem, and how you game a multiple choice question.)

Which is equal to 8^-10/8^5 ?
makkiz [27]
8^{-10} can be converted into \frac{1}{ 8^{10} } , and applying this to 8^{-5} can see that

\frac{ \frac{1}{ 8^{10} } }{ \frac{1}{ 8^{5} } }

This gives us 

\frac{ 8^{5} }{ 8^{10} }  =  \frac{1}{ 8^{5} } = 8^{-5}
