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:
$4.20
Step-by-step explanation:
y = .05x (using stat on calculator)
y = .05(84)
$4.20
X = number of years
78 + 7x = 111 + 4x
-78 from both sides
7x = 33 + 4x
Subtract 4x from both sides
3x = 33
Divid both sides by 3
X= 11
In 11 years both trees will be the same height.
Answer:
Original price=$12
Step-by-step explanation:
First set that up as an equation
9/a=75/100
Now cross multiply
75a=900
Then divide 75 from both sides for original price
75a/75=900/75
a=12
There's your answer
Hope this helped :)
12 - 2x - 3y5
12 - (2 * 4) - (3 * -4) 5
12 - 4 + 12 * 5
12 - 4 + 60
8 + 60
68
