Answer:
Its because the paper clips used here are of same length (4cm long).
So the measurements of lines two and three need to be multiples of 4 to me measured accurately with the paper.
i.e Line two needs to be 6cm + 2cm = 8cm (eight is a muliple of 4)
Line three needs to be 9cm + 3cm = 12cm (twelve is a multiple of 4)
Step-by-step explanation:
Since line 1 has 3 paper clips and its 12cm in length, the size of the paper clips is 4cm.
Line 2 is 6cm long and will require two more centimeters to measured accurately by the 4cm-paper clips.
Line 3 is 9cm and will require three more centimeters to be measured accurately by the 4cm-paper clips.
A) y=kx
2 = 16k
2/16 = k
0.125 = k
Y = 0.125x
B) y= 0.125x
Y= 0.125(7)
Y= 0.875
Hope this helps
Answer: Y = 2 ; 3 ; 4
Step-by-step explanation:
Given the rule : y=1/4x + 1
X = 4, 8, 12
When x = 4
y = 1/4(4) + 1
y = 1 + 1
y = 2
When x = 8
y = 1/4(8) + 1
y = 8/4 + 1
y = 2 + 1
y = 3
When x = 12
y = 1/4(12) + 1
y = 12/4 + 1
y = 3 + 1
y = 4
Therefore ;
X - - - 4 - - - 8 - - - 12
Y - - - 2 - - - 3 - - - 4
Answer:
Step-by-step explanation:
In a rectangle, diagonals are equal and bisect each other
BE = AE
6x - 5 = 2x + 7
6x - 2x - 5 = 7
4x - 5 = 7
4x = 7 + 5
4x = 12
x = 12/4
x = 3
AE = 2x + 7
= 2*3 + 7
= 6 + 7
AE = 13
AC = 13 + 13
AC = 26
m∠EBC = 50
In rectangle, each angle is 90
m∠ABE + m∠EBC = 90
m∠ABE + 50 = 90
m∠ABE = 90 - 50
m∠ABE = 40
In rectangle, AB // DC and DB transversal
m∠ECD = m∠ABE { alternate interior angles}
m∠ECD = 40
