Y1=4(5x-1), y2-=5x+1 and y1 is 344 more than 2 times y2

alisha [4.7K]

$y_1=4(5^x-1)$ and $y_2=5^x+1$

$y_1=344+2y_2$
$y_1=344+2(5^x+1)$
$4(5^x-1) = 344 + 2(5^x+1)$
$(4)(5^x)-4=344+2(5^x)+2$
$4(5^x)-2(5^x)=344+2+4$
$2(5^x)=350$
$5^x= \frac{350}{2}$
$5^x=175$
$log(5^x)=log(175)$
$x(log(5))=log(175)$
$x= \frac{log175}{log5}$
$x=3.21$ (rounded to two decimal places)

Solving system by substitution <br> Y=3x<br> Y=x+4

velikii [3]

So we're given Y = 3x.

We now can replace Y, for 3x in the equation:

Y = x + 4

3x = x + 4

3x - x = 4

2x = 4

x = 2

Lee watches TV for 2 hours per day. During that time, the TV consumes 150 watts per hour. Electricity costs (15 cents)/(1 kilowa

shutvik [7]

So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
