Let's take as example a linear function of the form:
 y = kx.
 Where,
 k is the constant of proportionality.
 Therefore, the proportionality constant is the point:
 (x, kx)
 Generically it is always the point:
 (x, k * f (x))
 Where, f (x) is a function proportional to x.
 answer:
 The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.

Can someone please help me! I'll give brainliest to who ever answers first with a positive answer
Effectus [21]

1. 3(p+q)=p

3p+3q=p; 3p-p=3q; 2p=q so p=q/2


2. 4a=2b-7

2b=4a+7 so b=(4a+7)/2

when a=3 , b=(12+7)/2=19/2=9.5


3. d=rt; r=d/t

4.( 2x15)+(2xwidth)=90

2x width=90-30

width =60/2=30

Using mixed numbers, write a problem in which an estimate is enough to solve the problem.​
KengaRu [80]

explain:

Estimating Differences of Fractions and Mixed Numbers

Estimating Differences of Fractions and Mixed NumbersRecall that estimation is a method for finding an approximate solution to a problem. Even when you are asked to find an exact ko, estimation is a useful way to get an idea of a reasonable solution to a problem. Once you have found an exact answer, you can check your answer against the estimate.

Ishaan is 2 times as old as Christopher. 35 years ago, Ishaan was 7 times as old as Christopher. How old is Ishaan now?
MrRissso [65]
I= Ishaan's age= 2C
C= Christopher's age

35 years ago means we have to subtract 35 from their current age. Ishaan minus 35 equals 7 times Christopher minus 35 years.

CHRISTOPHER'S AGE:
I - 35= 7(C-35)
substitute I=2C in for I
multiply 7 by all in parenthesis

2C - 35= 7C - 245

add 35 to both sides
2C= 7C - 210

subtract 7C from both sides
-5C = -210

divide both sides by -5

C= 42 Christopher's age


ISHAAN'S AGE:
I= 2C
substitute C=42 to find Ishaan's age
I= 2(42)

I= 84 Ishaan's age

CHECK:
Substitute answers in original equation

I - 35= 7(C-35)
84 - 35= 7(42-35)
49= (7*42)+(7*-35)
49= 294-245
49=49

Hope this helps! :)
