A quadrilateral has vertices at (1.4). (7,3), (3, -5), and (8,4). The
quadrilateral is dilated by a scale
factor of 3.5 with the origin as its
center. What are the coordinates of
the vertices of the image of the
quadrilateral?

a) (3, 12), (21, 9), (9, -15), (24, -12)

b) (3.5, 12), (24.5, 9), (10.5, -15), (28.5, -12)

c) (3.5, 14), (24.5, 10.5), (10.5, -17.5), (28, -14)

d) (3, 14), (21, 10.5), (9, -17.5), (24, -14)

please answer its 5am ive been up for hours

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

first one because it can't have a fraction in it

step-by-step explanation:

it is 570

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
