Answer:
−12≤p≤12
Step-by-step explanation:
Absolute value so the positive and negative of p.
p ≤ 12
-p≤12
divide by -1 (switch sign)
p≥- 12
P is greater than or equal to -12 but less than or equal to 12:
−12≤p≤12

y=kx and y=
are two equations of constant of proportionality
Step-by-step explanation:
There are two equations for the constant of proportionality. That is
(i) Direct proportion
(ii) Inverse proportion
In direct proportion y=kx, Now
if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.
In Inverse proportion y=
, Now
if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.
In direct proportion, we put y=1 and x=2, So k=
.
So, the equations y=kx and y=
are two equations of constant of proportionality.
Answer:
She has 3 $10 bills, 5 $5 bills and 8 $1
3 times 10= $30
5 times 5 = $25
8 times 1 = $8
$30 + $25 + $8 = $63
