Answer: The "?" would equal 1.
Step-by-step explanation: This is simply a line with a slope of 1 and a y-intercept of zero.
Answer:
Given: DB = 7.2 cm, AE = 1.8 cm and EC = 5.4 cm and DE || BC.
DB
AD
=
AC
AE
[by basic proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other two sides are divided in the same.
7.2
AD
=
5.4
1.8
AD=
5.4
7.2×1.8
AD=
10
24
⟹AD=2.4cm
_,___,___ -7 digit number
_,___,__0 - 0 in the ones place
_,_6_,__0 -6 in the ten thousands place
8,_6_,__0 -8 in the millions place
8,565,550 is your answer
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
2/3 x -4 = -2 add 4 to both sides
2/3 x -4 +4 = -2 +4
2/3 x = 2
mutliply both sides by 3/2
(3/2) * (2/3) x = (3/2) * 2
x =3
