What is the answer to..2/3 y + 3 = 29 ? I really don't understand this...please help.

Firstly, you bring over the the +3 to the opposite side so it is 2/3y = 29-3 So 2/3y = 26 So for fractions 2\3y =26/1 y= 2/3 divided by 26/1 so first you flip the equation so 26/1 times 3/2 so 26 x 3 = 78 and 1x2=2, so 78/2= 39 y=39

2/3y +3=29 so if you don't like fraction find a GCF which is three so multiply everything by three and you get 2y+9=87 subtract 9 on both side so 2y=78 and then divide by 2 on both side and y=39

How would the domain and range of the function y = one-fourth x minus 6 be determined? Explain.

Liono4ka [1.6K]

Answer:

Domain = ( -∞ , ∞ )

Range = ( ∞ , ∞ )

Step-by-step explanation:

A function is given to us and we need to find the domain and range of the given function .

The function :-

$\rm \implies y = \dfrac{1}{4}x - 6$

Definitions :-

Range :- The range is the set of all valid y values .
Domain :- All real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-

Domain :-

$\rm Domain = ( -\infty , \infty )$

$\rm Domain = \{ x | x \in \mathbb{R} \}$

Range :-

$\rm Range = ( -\infty , \infty )$

$\rm Range = \{ y | y \in \mathbb{R}\}$

Linda has d dollars in an account that pays 1.4% interest, compounded weekly. She withdraws w dollars. Express her first week’s

Fittoniya [83]

Answer:

If the 1.4% rate of interest is the weekly rate of interest, Then, total first week interest = 1.4(d - w)/100 = 0.014(d - w)

But if the 1.4% rate of interest is a yearly rate of interest compounded weekly, then her total first week interest = 7(d - w)/2600 = 0.00269 (d - w)

Step-by-step explanation:

The interest, I = PRT

P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)

R = rate of interest = 1.4% = 0.014/week

T = time = 1 week

If the 1.4% rate of interest is the weekly rate of interest

I = PRT = (d - w) × 0.014 × 1 = 0.014(d - w)

But if the 1.4% rate of interest is a yearly rate if interest compounded weekly,

P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)

R = rate of interest = 1.4% = 0.014/year

T = time = 1 week = (1/52) years

I = PRT = (d - w) × 0.014 × (1/52) = 7(d - w)/2600 = 0.00269 (d - w)

Hope this Helps!!!
