Step-by-step explanation:
3+√5+3√5+5
=6√5+5
=6√10
Second one
1/16
3/8 divided by 1/6=1/16
Step-by-step answer:
Given an enlargement from preimage (ABC) to image (A'B'C').
Need to find scale factor.
Solution:
Scale factor = linear size of image / linear size of preimage.
From the accompanying diagram, we see that
L(preimage) = AC = 4 units
L(image) = A'C' = 12 units
Therefore
Scale factor = L(image) / L(preimage) = 12 / 4 = 3
Y=mx+b b is the y intercept which is 4
m is the slope which is rise over run which is -4/2 which is -2
Linear y=-2x+4
