17x-3y=4 2x-4y=1 the solution to the system of equations is

Burka [1]

ANSWER

$x=\frac{13}{62}$

and

$y= \frac{-9}{62}$ e have

EXPLANATION

$17x-3y=4---(1)$

$2x-4y=1$

Let us make y the subject and call it equation (2)

$2x=1+4y$

$x=\frac{1}{2}+2y--(2)$

We put equation (2) in to equation (1)

$17(\frac{1}{2}+2y)-3y=4$

$\frac{17}{2}+34y-3y=4$

$34y-3y=4- \frac{17}{2}$

Simplify to get,

$31y= \frac{8-17}{2}$

$31y= \frac{-9}{2}$

Divide both sides by 31,

$y= \frac{-9}{2} \div 31$

$y= \frac{-9}{2} \times \frac{1}{31}$

$y= \frac{-9}{62}$

We put this value in to equation (2) to get,

$x=\frac{1}{2}+2\times -\frac{9}{62}$

$x=\frac{1}{2} -\frac{18}{62}$

We collect LCM to obtain,

$x=\frac{31-18}{62}$

$x=\frac{13}{62}$

At the start of the year, the balance in a married couple’s account is $ 1 , 750 . They decide to each deposit $ 35 into the acc

Dimas [21]

Answer:

f(n) = 1750 + 70n

Step-by-step explanation:

Since, each of them are depositing 35$ each month, they are adding 35x2 = 70$ each month.

So, in n months, they will be adding 70n $ to their account.

Initially, they had 1,750$ in their account. After n months, they should have 1750+70n $ in their account.

So, the function that represents this is, f(n) = 1750 +70n
