Y=4 because y is 4 all the time
Answer:
c=1/3F
Step-by-step explanation:
Answer:
the two number are 7 and 9
Step-by-step explanation:
2*x+y=25
3x-y = 20
add the two equations
2*x+y=25
3x-y = 20
---------------
5x = 45
divide by 5
5x/5 = 45/5
x = 9
lets find y
2x+y = 25
substitute x
2*9 +y =25
18+y =25
subtract 18 from both side
y = 25-18
y =7
XW must be congruent to YZ, and WZ must be congruent to XY
In order for it to be a parallelogram, the opposite sides must be congruent.
Answer:
rom the relation for linear regression formula, Y = b·X + a, we have ;
For car 1
ΣXY = 102780
(ΣX)² = 36
ΣX = 6
ΣY = 52390
ΣX² = 14
N = 3
b = -1000
a = 19463
Y = -1000×X + 19463
For Car 2
ΣXY = 102539.8
(ΣX)² = 36
ΣX = 6
ΣY = 52346.6
ΣX² = 14
N = 3 .
b = -1076.7
a = 19602
Y = -1076.7×X + 19602
