The number of calories k needed each day by a moderately active woman who weighs w pounds, is h inches tall, and is a years old can be estimated by the formula given below. upper k equals 917 plus 6 left parenthesis w plus h minus a right parenthesisk=917+6(w+h−a) julie is moderately active, weighs 119119 lb, and is 2121 years old. if julie needs 19371937 calories per day to maintain her weight, how tall is she?

72 inches

Step-by-step explanation:

Given : The number of calories k needed each day by a moderately active woman who weighs w pounds, is h inches tall, and is a years old can be estimated by the formula given below.

When w= 119 lb , a = 21 years ,  and k = 1937 calories, then we substitute all these values in the above function , we get:-

Hence, he is 72 inches tall.

expression #3 is not equivalent. the others are.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
