Answer:
D
Step-by-step explanation:
ΔWXZ and ΔYZX
WZ ≅XY {Given}
ZX ≅ ZX {Reflexive property}
∠W ≅ ∠Y
But for SAS congruent the congruent angles should between congruent sides( WX & WZ should be congruent to ZY & XY respectively).
So it cannot be proved using SAS congruent
X means one. so your slope is positive one and the y intercept is -5
The slopes of perpendicular lines are negative reciprocals.
If one line has a slope of 1/6, then the negative reciprocal would be -6/1 which is simplifies as -6.
The answer is C.
Answer:-47/40
Step-by-step explanation:
The expressions x2 - 14x + 49 and (x - 7)2 are equivalent.
(x + a)^2 = (x + a)(x + a) = x^2 + 2ax + a^2
In this case 2a = -14 so a= -7 and a^2 = 49
