Answer:
see below
Step-by-step explanation:
<em><u>sin(a+b) = sin(a)cos(b) + cos(a)sin(b)</u></em>
sin(π+q) = sin(π)cos(q) + cos(π)sin(q)
sin(π) = 0
cos(π) = -1
therefore
sin(π+q) = 0*cos(q) -sin(q) = -sin(q)
(2,3)(4,4)
slope(m) = (4-3) / (4-2) = 1/2
y = mx + b
slope(m) = 1/2
(4,4)...x = 4 and y = 4
now we sub
4 = 1/2(4) + b
4 = 2 + b
4 - 2 = b
2 = b
equation is : y = 1/2x + 2
Answer:x=1
Step-by-step explanation:
y=y
y = -x + 10
y = 7x + 2
-x+10=7x+2
10=8x+2
8=8x
x=1
Answer:
Step-by-step explanation:
Point (-7,-2) is the center of dilation. The scale factor is 2.
If point A has coordinates (-3,-2), then its image point H has coordinates (1,-2).
If point B has coordinates (-6,2), then its image point E has coordinates (-5,6).
If point C has coordinates (-4,3), then its image point F has coordinates (-1,8).
If point D has coordinates (-1,1), then its image point G has coordinates (5,4).
