4x+16y=32,4x+y=17 solve this inquestions​

Mathematics
1 answer:
diamong [38]3 years ago
6 0

answer:

x = ( -y + 49 )/ 8

step-by-step explanation:

good morning!

lets start off by adding both equations

4x + 16y = 32

4x + y = 17

+ ____________

8x + y = 49 <--------- our new starting equation

first we need to move the variable ( y ) to the other side of the equation, in other words separate them

8x = 49 + y

then lets rearrange the expression

8x = −y + 49

we need to still divide both sides by 8 to get ( x ) by itself

8x/ 8 = ( −y + 49 )/ 8

turning this equation into your new answer!

x = ( -y + 49 )/ 8   <-------------- our answer!

i hope this helps you! and if i read the question/ or made it a little confusing then please let me know, i hope you have a good rest of you day :)

The current (I) varies directly as the voltage (V) in an electric circuit. If the current is 4 amperes when the voltage is 100 v

Create an example of a situation where there is a negative cash flow.
dimaraw [331]

Answer:

when say your expenses are $400 a month but your income is only $350 a month that is -$50 every month so in that case you aren't getting a positive cash flow (which would be making more money than your expenses) So you must be getting a negative cash flow in which you are losing money and going into debt.

Hope this Helps :)
