This situation can be represented by

y = 33x + 223

y = 32x + 239

I still like substitution, so let’s plug in 33x + 223 into the second equation

33x + 223 = 32x + 239

Move the terms into appropriate sides

33x - 32x = 239 - 223

Combine like terms

x = 16

Then plug in x for any equation

y = 32(16) + 239

y = 751

Help me please??????
Natasha2012 [34]

Answer:

y=-3x-3

Step-by-step explanation:

To get a perpendicular line you take the negative reciprocal of the slope, so in this case it would equal -3. Now use point-slope form to get your equation. Point slope form says that y-y1=m(x-x1) where m is your slope and x1 and y1 are the points that the graph passes through. So in this case x1=-3, y1=6, and m=-3. This gives you the equation y-6=-3(x+3). Distribute to y-6=-3x-9, and finally add 6 to both sides to get y=-3x-3

What is $920.86 rounded to the nearest 100 dollars?
nlexa [21]

Answer:

$920.86 is rounded to $900

Step-by-step explanation:

The 9 is the hundred place, the 2 is the ten place, the 0 is the ones place, 8 is the tenth, 6 is the hundredth.

So nine-hundred and twenty is rounded to 900.

This is because any number that is 5 or below stays the same, so if the 920 is instead 960, you would round the answer to 1000.

So, 920.86 is rounded to 900.
