First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0                                        x + 4 = 0
add 6 to both sides                      subtract 4 from both sides
x = 6                                             x = -4
The function would be undefined if x = 6 or x = -4

A farmer saved $250 in four months. Which unit rate represents the farmer's savings? $1000 per year $1000 per month $750 per yea
Furkat [3]

Answer:

$750 per year

Step-by-step explanation:

The farmer saves $250 in four months.  You need to find out how much he makes in a year.  There are 12 months in a year.  Multiply the amount he saves by 3.

$250 × 3 = $750

The farmer saves $750 per year.

HELP I NEED HELP ASAP
pickupchik [31]

Answer:

D

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = \sqrt{2080}

c = 45.61

The answer is 45.61 units.
