Answer:

-2 and 4

Step-by-step explanation:

Graph it using a graphing calculator.  The solutions are the points where the graph crosses the x-axis.

I attached a photo of the graph, you can see that the graph crosses the x-axis at points -2 and 4

These are the solutions!

A circle has a radius of square root 98 units and is centered at (5.9, 6.7). Write the equation of this circle. Please help!
weqwewe [10]

<u>Given</u>:

Given that the radius of the circle is √98 units.

The circle is centered at the point (5.9, 6.7)

We need to determine the equation of the circle.

<u>Equation of the circle:</u>

The general form of the equation of the circle is given by

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius of the circle.

Substituting the center point (h,k) = (5.9, 6.7) and r = √98, we get;

(x-5.9)^2+(y-6.7)^2=(\sqrt{98})^2

Simplifying, we get;

(x-5.9)^2+(y-6.7)^2=98

Thus, the equation of the circle is (x-5.9)^2+(y-6.7)^2=98

Find the value of n and WX if W is between X and Y, WX=6n-10, XY=17, and WY=3n
Neko [114]

Answer:

n = 3

Step-by-step explanation:

It is given that W is between X and Y. It means,

WX = WY

or

XY = WX+WY

We have, WX=6n-10, XY=17, and WY=3n

So,

17= 6n-10+3n

Adding both sides 10

17+10= 6n-10+3n+10

27=9n

n = 3

Hence, the value of n is 3.
