Answer:
y = -3x + 4
Step-by-step explanation:
sorry im late
but all you have to do is isolate the y
so to do that we have to get rid of the 3x
3x + y = 4
in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y
3x + y = 4
-3x -3x
y = -3x + 4
and now y is isolated
<u>Solution-</u>
1- When rotating a figure 180 degrees around the origin (As it does not matter whether you move clockwise or counter-clockwise), we apply the rule (x, y) → (-x, -y).
Co-ordinates of the vertices,
P = (1, -1)
Q = (3, -2)
R = (3, -4)
And then calculating the co-ordinates of P', Q', R'
P' = (-1, 1)
Q' = (-3, 2)
R' = (-3, 4)
2- When reflecting a figure across X-axis, we apply the rule (x, y) → (x, -y).
Co-ordinates of the vertices,
P' = (-1, 1)
Q' = (-3, 2)
R' = (-3, 4)
And then calculating the co-ordinates of P'', Q'', R''
P'' = (-1, -1)
Q'' = (-3, -2)
R'' = (-3, -4)
Answer:
108
Step-by-step explanation:
Hey There!
So the arc is equal to its corresponding angle
We are given the angle of KL which is 30 so all we need to do is find the length of arc JK
The angles given and the missing angle are supplementary angles meaning that they will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-30-72=78
Now we just add arc JK and arc Kl
30+78=108
so arc JL is equal to 108
