What is the distance between the two points (-2 ,1 )and (4, 3)

Solution:

Distance between two points = √(3−4)^2+(−2−3)^2

= √(−1)^2+(−5)^2

= √1+25

= √26

= 5.099

Distance between points (4, 3) and (3, -2) is 5.099.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
