Answer:
There are infinitely many solutions to the system because the equations represent the same line.
Step-by-step explanation:
Rearrange the 2nd equation
-36a-24b-16c
divide the whole thing by 4 and you'll get
-9a-6b-4c
you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7
multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28
so the answer you want is -28
Answer:
d(x) = 175 - |175 - 25x|
Step-by-step explanation:
Suppose I plan to ride your bicycle from Portland Oregon to Seattle Washington and back to Portland.
Portland and Seattle are 175 miles apart. I plan to travel 25 miles every day.
If we consider the starting point i.e. Portland as the zero distance i.e. reference, then we can model the distance from Portland d(x) as
d(x) = 175 - |175 - 25x|
where x is the number of days into the ride. (Answer)
450÷50=9
Your answer would be 9inches because all you have to do is divide 450 by 50 and you get the number of inches
The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
