Assume body weight and height are related by the formula W=2H+13, where W represents weight in pounds and H represents height in

yulyashka [42]

Given the equqation
W = 2H + 13
where
W is the weight in lb
H is the height in inches

If the height of a person is 5 ft 6 in, we must first convert it to inches. So,
H = 5(12) + 6
H = 66 in

The body weight then is,
W = 2(66) + 13
W = 145 lbs

If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5

Tema [17]

Answer:

$y=-30$

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

$y=kx$

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

$6=k(-1)$

so, we get

$k=-6$

now, we can plug it back

$y=-6x$

now, we can plug x=5

and we get

$y=-6\times 5$

$y=-30$
