Answer:
It's the first one
Step-by-step explanation:
basically what the law of syllogism is is that If p equals q and if q equals r, then p equals r.
so, p=q=r
so, p=r
Answer:
c. 40°
Step-by-step explanation:
The information given has been illustrated in the figure drawn in the attachment below.
m<BAD = 50° (angle bisector theorem)
m<ADB = 90° (perpendicular bisector)
m<ABD = 180 - (m<BAD + m<ADB) (sum of angles in a triangle)
m<ABD = 180° - (90° + 50°)
= 180° - 140°
= 40°
B = 40°
Answer:
Step-by-step explanation:
A. 2x+3y+z
X = -2
Y= -3
Z= 5
2(-2)+3(-3)+5
-4-9+5
=8
B. X-Y
-2–3
-2+3
=1
C. 2(x+y/z)
2(-2-3/5)
2(-1)
=-2
D. 3x^2-2x+1
3(-2)^2-2(-2)+1
3(4)+4+1
=17
E.3y(x+x^2-y)
3(-3)(-2+-2^2-(-3))
-9(1)
=-9
F.-z^2(1-2x)/y-x
5^2(1-2(-2)/-3–2
25(5/5)
25(1)
=25
V (-1,-9)
Y=1(x+1)^2-9
If you’re talking about the value of x in the quadratic equation then it is x=-4 &x=2
