Please help with a math problem :/ Please show steps... x^2 -13x = -36

Mathematics

X^2 -  13 x = -36 
add 36 to both sides

x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}

Find the equation of a line that is perpendicular line to y = 10x - 45 and goes through (1, 1).
Airida [17]

The line y = 10x - 45 is already written in the y = mx+q form. This means that m is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.

So, our perpendicular line has a slope of -\frac{1}{10}

Finally, we want a line passing through (1,1) with slope -\frac{1}{10}:

y-1 = -\dfrac{1}{10}(x-1) \iff y = -\dfrac{x}{10} + \dfrac{1}{10}+1 = -\dfrac{x}{10} + \dfrac{11}{10}
