Answer:
Option (6). HL
Step-by-step explanation:
Given:
From the right triangles ΔBAC and ΔBDC,
AC ≅ CD
∠A = ∠D = 90°
To Prove:
ΔBAC ≅ ΔBDC
Statements Reasons
1). AC ≅ DC 1). Given
2). BC ≅ BC 2). Reflexive property
3). ΔABC ≅ ΔBDC 3). By HL property of congruence of right triangles
Therefore, Option (6) HL will be the correct option.
I'd start by calculating the determinant of the coefficient matrix. That's a cubic in k. Then find the values of k that make this determinant 0.
<span>When the determinant is not 0, the system has a unique solution. </span>
<span>When the determinant is 0, the system is linearly dependent and has infinite solutions, or is inconsistent and has no solutions. Which option depends on the constants on the right. </span>
<span>So take each value of k that makes the system 0, and see whether the equations are identical or inconsistent. </span>
Step-by-step explanation:
what are the given values of x ?
there is nothing visible.
and what is the function itself ? f(x) = 7x ?
it is not clear.
