What is the answer to x^2-11=25 please
Westkost [7]

Hey there!

\mathsf{x^2 - 11 = 25}

\large\textsf{ADD 11 to BOTH SIDES}

\mathsf{x^2 - 11 + 11 = 25 + 11}

\large\textsf{CANCEL out: -11 + 11 because that gives you 0}

\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}

\mathsf{25 + 11 = \bf 36}

\large\textsf{NEW EQUATION: }\mathsf{x^2=36}

\large\textsf{Take the square root of the number (36)}

\mathsf{x = \pm \sqrt{36}}

\mathsf{\pm = \boxed{\bf plus-or-minus}}

\mathsf{x = \sqrt{-36}\rightarrow \bf -6}

\large\textsf{or}

\mathsf{x = \sqrt{36} = \bf 6}

\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark

\large\text{Good luck on your assignment and enjoy your day!}

Enter the slope-intercept equation of the line that has slope 12 and y-intercept<br> (0,3).
Nadya [2.5K]

Answer:

y=12x+3

Step-by-step explanation:

The slope-intercept form is y=mx+b. In the equation for slope-intercept form m=slope and b=y-intercept. You have the slope and y-intercept so all you have to do is put them in the right places. Since the slope is 12 your put the 12 where the m is and get y=12x+b. Then since you know the y-intercept is (0,3)=3 then you just need to put the 3 where the b is to get y=12x+3.

Hope this helps!!!
