Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? determine the solution set algebraically. (–5, –80) (5, 0) (5, 0) and (–5, –80) no solutions

Given the system of equation:

         .....[1]

                ......[2]

Equate these two equations we get;

Subtract 8x to both sides we have;

Add 40 to both sides we have;

Using the identity rule:

then;

⇒

Add 5 to both sides we have;

x = 5

Substitute this value in [2] we have;

y=8(5)-40 = 40-40 = 0

therefore, the solution(s) of the system of equations is, (5, 0)

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

any options?
