Question

If y is propotional to 4x + 1 and y=3 when x= 2 find: a) an equation connecting x and y b) the value of y when x= 5 c) the value of x when y = 11
please ans the question i will mark you as brainliest

Answer 1

Answer:

Step-by-step explanation:

We know that,

y∝4x+1

So, when y=3

x=2

a) y = k(4x+1)

b) If x=5 then y = ?

y ∝ 4x+1

when y = 3 then x = 2

3 = k (9)

y = k(21)

so,

21*3 = y*9

7 = y

c) y=11

so,

3(4x+1) = 11*9

=>12x+3 = 99

=> 12x = 96

=> x = 8
