The reciprocal of a number is 1 divided by the number. 1/4=0.25.
Answer:
y = 1/3a
Step-by-step explanation:
y = ka
1 = 3k
k = 1/3
Confirm constant: (4-1)/(12-3) = 3/9 = 1/3
1 = 3(1/3) + b
1 = 1 + b
b = 0
y = 1/3x or 1/3a
B) y=2/3x + c because generally the equation of a line is y=mx + c
Answer:
No solution.
Step-by-step explanation:
−3> 7x−8 > −0.2
Split this into 2 inequalities:
7x - 8 < -3 Add 8 to both side:
7x < 5
x < 5/7.
and:
7x - 8 > -2 Add 8 to both sides:
7x > 6
x > 6/7.
But x cannot be both less than 5.7 and > 6.7, so No solution.
