Answer:
Add and subtract the second term to the expression and factor by grouping .
(x-1)(x+1)(x-3)(x+2)
The solution is that x = 26 and y = 9.
In order to find these, we need to note that since the two angles involving x's make a straight line, then they must equal 180 degrees. So we can add them together and set them equal to solve for x.
5x - 17 + 3x - 11 = 180 ----> combine like terms
8x - 28 = 180 ----> add 28 to both sides
8x = 208 -----> divide by 8
x = 26
Now that we have the value of x, we can find the value of the 3x - 11 term. That along with the right angle and the 2y + 5 angle combine to make another straight line. So we can solve by setting that equal to 180 as well.
3x - 11 + 90 + 2y + 5 = 180 ------> Combine like terms
3x + 2y + 84 = 180 -----> Put 26 in for x.
3(26) + 2y + 84 = 180 -----> Multiply
78 + 2y + 84 = 180 ------> Combine like terms again
2y + 162 = 180 ------> Subtract 162 from both sides
2y = 18 -----> Divide by 2
y = 9
The slope of this line is 1/2.
In order to find the slope of any equation, you can take two points and use the slope formula. For ease, we'll use the two intercepts that you can see: (0, -3) and (6, 0). The formula for slope is below.
m = (y2 - y1)/(x2 - x1)
In this equation, m is the slope and (x1, y1) is the first ordered pair and (x2, y2) is the second. So we place those values in to solve for m.
m = (y2 - y1)/(x2 - x1)
m = (0 - -3)/(6 - 0)
m = 3/6
m = 1/2
And that is your slope.
Answer:
36
Step-by-step explanation:
so 50% of 120 is just half of it. so that would be 60. Then 20% of 120 is 24 so subtract that from 60 and you get 36.
I this it would be constant correlation
