Answer:
First, we need to know the formula when a scale factor appears:
New coordinate = (scale factor)*(old coordinate)
So using this formula we have:
1) c' = (-2,1)*2/3
c' = (-4/3,2/3)
2) r = (-5,2)*2/3
r = (-10/3,4/3)
3) a = (-6,7)*2/3
a = (-4,14/3)
4) f = (-3,9)*2/3
f = (-2,6)
5) t = (-1,6)*2/3
t = (-2/3,4)
Answer:
Step-by-step explanation
(2/3) (60/99) = (2/99)(60/3) = (2/99)(20) = 40/99 = .040404......... So.......the sum of the first 15 digits = 7(4) + 7(0) + 0 = 28.
Answer:
y=6x+3
Step-by-step explanation:
A line that is parallel to another line, has the opposite slope of the first line.
Answer:(3,0)
Explanation:To find the x substitute 0 in for y,7x+3*0=21.Next,multiply 3 and 0,and that gives you 0,7x+0=21 .After you do that you need remove 0 because when you add and subtract zero the quantity doesn’t change,7x=21.Lastly,divid both sides of the equation by 7,and that gives you x=3.
