Please help I'm struggling so bad right now
Over [174]

Answer:

y = m x + b     is the standard form of a straight line

m = (y2 - y1) / (x2 - x1) = (10 - (-8)) / (-3 - 0) = 18 / -3 = -6

When x = 0 y = b from the equation for a line

y = - 8

So our equation is  

y = -6 x - 8

As a check let x = -2 then

y = (-6 * -2) - 8 = 12 - 8 = 4

Check on the graph to verify that this equation holds

Solve for X-4 1/6 = 9 1/3
Gala2k [10]

Answer:

  13 1/2

Step-by-step explanation:

X-4 1/6 = 9 1/3

Add 4 1/6 to each side

X-4 1/6+ 4 1/6 = 9 1/3 + 4 1/6

x = 9 1/3 + 4 1/6

  = 9 2/6 + 4 1/6

   13 3/6

    13 1/2

Explain how you would round the numbers 33 and 89 ti estimate their sum
Anna11 [10]
 Depending on what numbers I'm rounding to, hundreds, tens, ones etc

If the ones place is 4 and lower, I would round to 30. If the ones place is 5 and higher, you would round to the next tens place. That would make 89 to 90.


Hope This Helps!
