Answer:

a. Non proportional

b. Proportional

c. Non proportional

Step-by-step explanation:

Here, we want to determine if each situation is proportional or not

a) Non-proportional

This is because the amount y paid in a month will be;

y = 1400x + 150

Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship

b) proportional

y = 3/4x

The value of y is dependent solely on that of x, so the relationship is proportional

c) non proportional

Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional

A student was required to multiply a number by 4 and add 6 to it. Instead he added 6 to it first and then multiplied by 4. What

GalinKa [24]

Answer:

The correct answer is 18

the correct expression is $(4n+6)$

Step-by-step explanation:

let the number be n

therefore if he is required to multiply n by 4 and added to 6 we have

$(4n+6)= 0-----1$

given that he did otherwise by adding 6 to n and multiply by 4 we have

$(n+6)4= 36------2$

Firstly we need to solve for n in equation 2

$4n+24= 36\\4n= 36-24\\4n= 12\\$

Dividing both sides by 4 we have

$n= \frac{12}{4\\}\\n= 3$

In order to solve for the correct answer let us input n=3 in equation 1 we have

$=(4n+6)= 0-------1\\=(4*3+6)= 0\\=(12+6)=0\\= 18$

balandron [24]

Hello,
$u_{1}=4\\
u_{2}=4*3=12\\
u_{3}=4*3^2=36\\
u_{4}=4*3^3=108\\
...\\

\boxed{u_{n}=4*{n-1}}\\$
