Answer:

\left ( x+5 \right )^{2}+\left ( y-6 \right )^{2}= 9

Step-by-step explanation:

The power station is located 5 miles west and 6 miles north of the center of town. So if we try to locate the above points on a Cartesian plane. The co-ordinates of these points will be (-5,6).

And it is also mentioned that a power outage affected all homes and businesses within a 3 mile radius of the power station. So if we plot all the furthest points from the station affected by the power outage it will be a circle of radius 3 miles and center at  (-5,6).

The equation of a circle with center (a,b) and radius r is given by :

\left ( x-a \right )^{2}+\left ( y-b \right )^{2}= r^{2}

Hence the equation of the resulting circle will be: \left ( x+5 \right )^{2}+\left ( y-6 \right )^{2}= 3^{2}

8x + 6 - 2x = 34 x= ?
e-lub [12.9K]
8x + 6 - 2x = 34x

Simplify 8x +6 - 2x to 6x + 6:
6x + 6 = 34x

Subtract 6x from both sides:
6 = 34x- 6x

Simplify 34x - 6x to 28x:
6 = 28x

Divide both sides by 28:
\frac{6}{28} = x

Simplify \frac{6}{28} to \frac{3}{14} :
\frac{3}{14} = x

Now switch sides and the answer is:

x = \frac{3}{14}

Answer:

It is A [1st option]

Step-by-step explanation:

Use process of elimination.

The last 2 would not work since 3^0 is 1 not 0.

Then you can eliminate the 2nd option as it says 2^3^2 is 2^5 which is wrong... it would be 2^6

Therefore, it is A

HELP ASAP WILL GIVE BRAININST IF:
DiKsa [7]

Answer:

<em><u>slope is -7/8</u></em>

Step-by-step explanation:

ok

first remember these to formulas:

m= \frac{y2-y1}{x2-x1}

and

y-y1 = m(x-x1)

now insert the points:

\frac{-3-4}{3-(-5)}= -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y =  -7x/8 - 3/8

Have a nice day!

and if you have a question or if I did anything wrong please tell me.
