Answer:
y=1/2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-7-(-1))/(-8-4)
m=(-7+1)/-12
m=-6/-12
m=1/2
y-y1=m(x-x1)
y-(-1)=1/2(x-4)
y+1=1/2x-4/2
y=1/2x-2-1
y=1/2x-3
As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
If the frame to hold the picture is 25 5/6 inches height, then the picture to put in it should be the same height: <span>25 5/6 inches
perhaps a little bit smaller for it to fit properly</span>
26 to nearest year
We require the total of the sums of ages for both groups before calculating the mean for all 16
using mean = 
Women
27 = 
( cross- multiply )
sum = 9 × 27 = 243
Men
25 = 
( cross- multiply )
sum = 7 × 25 = 175
Total sum of all 16 = 243 + 175 = 418
mean = 
= 26 ( to nearest year )
