We can write this as an inequality:
$1 + 3x \ \textless \ x - 5$

We can deal with this very easily:
$1 + 2x \ \textless \ -5$
$2x \ \textless \ -6$
$x \ \textless \ -3$

I solved it for you, I cannot graph due to Brainly not supporting it. Sorry, and hope this helps!

Solve this using elimination method 5x+25y=60 3x+15y=42

hoa [83]

5x + 25y = 60....multiply by -3
3x + 15y = 42....multiply by 5
-------------------
-15x - 75y = - 180 (result of multiplying by -3)
15x + 75y = 210 (result of multiplying by 5)
-------------------add
0 = 30...incorrect.....this system has no solutions

URGENT!!! 30 POINTS!!! Expand log(1/2)(3x^2/2) using properties and rules for logarithms.

Korvikt [17]

$\log_\frac{1}{2}\left(\dfrac{3x^2}{2}\right)=\log_\frac{1}{2}3x^2-\log_\frac{1}{2}2=\log_\frac{1}{2}3+\log_\frac{1}{2}x^2-\log_\frac{1}{2}2\\\\=\log_\frac{1}{2}(3)+2\log_\frac{1}{2}(x)-\log_\frac{1}{2}\left(\dfrac{1}{2}\right)^{-1}\\\\=\log_\frac{1}{2}(3)+2\log_\frac{1}{2}(x)-\left[-\log_\frac{1}{2}\left(\dfrac{1}{2}\right)\right]\\\\=\log_\frac{1}{2}(3)+2\log_\frac{1}{2}(x)+\log_\frac{1}{2}\left(\dfrac{1}{2}\right)\\\\=\boxed{\log_\frac{1}{2}(3)+2\log_\frac{1}{2}(x)+1}$

$Used:\\\\\log_a\dfrac{b}{c}=\log_ab-\log_ac\\\\\log_a(bc)=\log_ab+\log_ac\\\\\log_ab^n=n\log_ab\\\\\log_aa=1$

Adam earns $36 for every four hours of work. If he continues to be paid at the same rate. How long will it take him to earn $225

prisoha [69]

Answer:

It will take him 6.25 hours to earn $225

Step-by-step explanation:

225 ÷ 36 = 6.25

6.25 = 6 1/4

You are dividing the total amount of money needed to be earned ($225) by the amount of money he gets paid every hour ($36) to get the number of hours it will take him to earn the amount of money he wants to earn.

Hope this helps!
