A point is set up like (x,y)
Since horizontal movement is movement in the x-axis, the x part of the point would change.
Since horizontal changes appear as the opposite inside the parentheses, 9 units right would be -9
-3-9= -12
A change up or down is a change in the y-axis. So, 10 units down would be 15-10=5
So, the new point is (-12,5)
Answer:
a = 30°
Step-by-step explanation:
We need to find the value of a.
We know that, a straight line makes an angle of 180°.
In this case,
a+3a+2a = 180
6a = 180
a = 30°
So, the value of a is equal to 30°.
Answer:
y-1=-2/3(x-5)
Step-by-step explanation: You have to use slope formula to find the slope, Then you use the first set of points because it have to be x1
Answer:
They are parallel lines
Step-by-step explanation:
Firsr you have to put both of the equations in slope intercept form which is y=mx+b and line 1 that would be 4y=3x+12 then you divide the slope and the y-intercept by 4 to get ride of the 4 in front of the y and it would equal y=3/4x+3 and for line 2 you do the same and that put into slope intercept form would be 2y=1.5x-14 so you do the same and divide the slope and the y-intercept by 2 which would equal y=0.75x-7 and 3/4 in decimal form would be 0.75. since the slopes are the same the lines would be parallel
Answer:
146°
Step-by-step explanation:
The measure of the arc EF is equal to the angle subtended at the centre.
That is EF = 146°
