Make a proportion of corresponding sides
Side AU corresponds to Side AB
Side UV corresponds to Side BC
Find AB by adding AU and UB
AU = 20x + 108
UB = 273
AB = 20x + 381
Make proportion
AU/AB = UV/BC
20x + 108/ 20x + 381 = 444/ 703
Cross Multiply
(20x + 108)(703) = (20x + 381)(444)
14,060x + 75,924 = 8,880x + 169,164
Solve for x
14,060x + 75,924 = 8,880x + 169,164
I'm sure you can figure this out
The regression equation:
y = m x + b
m = ( 57 - 50 ) / ( 178 - 168 ) = 7 / 10 = 0.7
50 = 0.7 * 168 + b
50 = 117.6 + b
b = 50 - 117.6
b = - 67.6
y = 0.7 * x - 67.6The graph is in the attachment.
The weight of supermodel who is 171 cm tall:
y = 0.7 * 171 - 67.6 = 119.7 - 67.6 =
52.1 kg
Hi there!
To find f(-2), we need to plug in the value x = -2 into the equation.

Remember that multiplying a negative by a positive ends up with a positive.
