The difference between the solutions to the equation x2 =a is 30 what is a ?
Mademuasel [1]
Given equation is x^2 = a

In general solution of x^2 = b is x = + \sqrt{b} and x = -  \sqrt{b}

So the solution of given equation is x = + \sqrt{a} and x = -  \sqrt{a}

Now difference between them is 30.
So we can write
\sqrt{a} - (- \sqrt{a}) = 30
\sqrt{a} +  \sqrt{a} = 30
2 \sqrt{a} = 30
\sqrt{a} = 15

On squaring both side
( \sqrt{a})^2 = (15)^2
a = 225

slamgirl [31]

Answer:

B'(-5,-6)

Step-by-step explanation:

The mapping for 180° clockwise rotation about the origin is:

(x,y)\to (-x,-y)

The find the image of B(5,6), we plug in x=5 and y=6 into the rule.

(5,6)\to (-5,-6)
