Well if you already know how to write an equation for a given set of proportions, then all you have to do is replace the unknown value with x, and then cross multiply and solve the equation. One important thing to remember is that for each proportion the numerator and the denominator have to be of the same units in the equation.

Anika [276]
Once you find your common denominator (24) you have to do the same to the numerator. So for the roses it would be 9/24 + 8/24 which is 17/24 for both roses and geraniums

Find the equation of a line tangent to the circle (x−1)^2+y^2=26 at the point (2, −5).
77julia77 [94]

Center of circle is ( 1, 0).

Slope of normal passing though ( 1, 0 ) and ( 2, -5 ) is :

m_p=\dfrac{0-(-5)}{1-2}\\\\m_p=-5

So, slope of tangent will be :

m_t=-\dfrac{1}{m_n}\\\\m_t=\dfrac{1}{5}

Equation of tangent :

y-(-5)=\dfrac{1}{5}(x-2)\\\\5y+25=x-2\\\\5y-x+27=0

Hence, this is the required solution.

shutvik [7]
You plug in the given value for x.

F(-4)=(-4)2-4
F(-4)=-8-4
F(-4)=-12

F(0)=(0)2-4
F(0)=0-4
F(0)=-4

F(3)=(3)2-4
F(3)=6-4
F(3)=2
