Answer:
one solution (-2 ; 5)
Step-by-step explanation:
hello : 2x + 3y= 11
...(*)
-x-5y=-23.....(**)
by(**) : x= -5y+23
put this value into (*) : 2(-5y+23)+3y=11
-10y+46+3y=11
-7y = -35
y=5
but x= -5y+23
so : x= -5(5)+23 =-2
Answer:
The correct answer is "decrease, 1,280 feet".
Step-by-step explanation:
The given values are:
Rate or speed,
= 320 feet per hour
1 pm to 5 pm means,
t = 5 - 1
= 4 hours
Now,
The net change in distance will be:
⇒ 
⇒ 
Thus the above is the correct approach.
The answer is irrational I believe. It’s not a decimal that just ends.
Answer:
Line A
Step-by-step explanation:
Answer: Everything except 3 * 129
Step-by-step explanation:
You can break 388 in half twice in order to find the answer.
Since 388/2 = 194, then 194 * 2 = 388
Since 388/4 = 97, then 97 * 4 = 388
Do note that 3 and 129 are both odd. Two odd factors can never make an even product. So that is out immediately.
Hope this helped a little bit, I tried to be quick with the explanation because I know how annoying those online things are. If you need anything explained more, just let me know.
