(1,2/3)(-1,-1)
slope = (-1 - 2/3) / (-1 - 1) = (-3/3 - 2/3) / (-2) = (-5/3) / -2 = -5/3 * - 1/2 = 5/6
y = mx + b
slope(m) = 5/6
(-1,-1)..x = -1 and y = -1
now we sub and find b, the y int
-1 = 5/6(-1) + b
-1 = - 5/6 + b
-1 + 5/6 = b
-6/6 + 5/6 = b
-1/6 = b
so ur equation is : y = 5/6x - 1/6
Answer:3x-4y
Step-by-step explanation:
To express the sum of (2x-5y) and (x+y),
We are going to have
2x-5y+x+y
The next thing to do is to collect the like terms;
Then we have;
2x+x-5y+y
Answer realized will now be
3x-4y
Answer:
6.2
Step-by-step explanation:
First divide 25 by 4, you get 6.25, then round up. I am not sure if this is entirely right, the question is a little confusing.
So to solve for an inequality, you must isolate the variable, in this case x, to one side.
Starting with 3.5x - 10 > -3, firstly add both sides by 10:
3.5x > 7
Next, divide both sides by 3.5 and your first half is:
x > 2
Next with 8x - 9 < 39, firstly add both sides by 9:
8x < 48
Next, divide both sides by 8 and your second half is:
x < 6
<u>Putting it together, your final answer is x > 2 and x < 6 or 2 < x < 6.</u>
