Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112

Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!

Prove or disprove that the circle with equation x^2-4x+y^2=-3 intersects the y axis
wel
The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.

Use completing the square method:

x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1

the center of the circle is (2,0) and r = 1

To check if it intersects the y axis, find the value of the x-intercept.

Match each as either linear or non-linear. HELP​
Virty [35]

Answer:

<u>Linear</u>

y=-x

y  =  \frac{x}{9}

-  \frac{2}{3}x + 3y = 1

<u>Non linear</u>

y =  \frac{4}{x}

\frac{2}{y}  = x

{x}^{2}  +  {y}^{2}  = 1

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

y =  \frac{x}{9}  \: is \: also \: linear.

y =  \frac{4}{x}  \implies \: xy = 4

The degree of this equation is 2.

It is non-linear

-  \frac{2}{3}x + 3y = 1

is also linear.

\frac{2}{y}  = x \implies \: xy = 2....non - linear

{x}^{2}  +  {y}^{2}  = 1.....non - linear
