What are the coordinates of the image of triangle TUV following a dilation with the scale factor of 2 centered at the origin ( Please help it would mean a lot to me !!
a 4/6 = 9/12 not proportional
step-by-step explanation:
to find which are not proportional, we can use cross products
if it is true, they are proportional. if it is not true, they are not proportional.
a 4/6 = 9/12
4* 12 = 6*9
48 = 54
not this is not proportional
b 2/3 = 12/18
2* 18 = 3 * 12
36 = 36
this is proportional
c 5/4 = 10/8
5*8 = 4*10
40 = 40
this is proportional
d 7/5 = 35/25
7*25 = 5 * 35
175 = 175
is proportional
7/2
(decimal: 3.5)
welcome ; )
step-by-step explanation:
constant of proportionality = 3 and the equation is c = 3p.
step-by-step explanation:
c = kp where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.
substituting the values given:
24 = 8k
k = 3.
the same value of k will be obtained if we substitute the other given values.
