{\tt{x =  \frac{ -b± \sqrt{ {b}^{2} - 4ac } }{2a} }}

{\tt{ x =  \frac{ - 5±\sqrt{{5}^{2}  - 4 \times 1 \times ( - 3)} }{2 \times 1} }}

{\tt{x =  \frac{ - 5±\sqrt{25 + 12} }{2} }}

{\tt{x =  \frac{ - 5 ±\sqrt{37}  }{2} }}

\:  \:

{\tt{x =  \frac{ - 5 +  \sqrt{37} }{2} }}

{\tt{x =  \frac{ - 5 -  \sqrt{37} }{2} }}

Hello from MrBillDoesMath!

Answer:

x = 0, 7

Discussion:

f(g(x)) =

f ( x^2-7x) =

1/ ( x^2 - 7x)


The points NOT in the domain are those where the denominator,  x^2 - 7x = 0.

x^2 - 7x   = 0       =>       factor x from each term

x(x-7) = 0            =>        one or both terms must each 0

x = 0 or x =7


Thank you,

MrB

In the diagram, AITP - ANGO. Find the values of<br> x and y.<br><br> y =<br> X=
Zepler [3.9K]

Answer:

x = 25, y = 9

Step-by-step explanation:

Since the triangles are congruent then corresponding angles and sides are congruent, thus

∠ O = ∠ P , substitute values

6y - 14 = 40 ( add 14 to both sides )

6y = 54 ( divide both sides by 6 )

y = 9

and

NG = IT , that is

x - 2y = 7 ( substitute y = 9 into the equation )

x - 2(9) = 7

x - 18 = 7 ( add 18 to both sides )

x = 25
