Sam is trying to lose weight and george is trying to gain weight. sams weight in pounds can be represented by the function f(x)=240-2x, where x is the number of weeks since sam started losing weight. george's weight since sam started losing weight. george's weight in pounds can be represented by the function g(x)=180+4x, where x is the number of weeks since george starting gaining weight. what is the x value when f(x)=g(x)?

x=10

Step-by-step explanation:

Given : Sams weight in pounds can be represented by the function , where x is the number of weeks since Sam started losing weight.

George's weight in pounds can be represented by the function  , where x is the number of weeks since George starting gaining weight.

When

To find x, first we add 2x on both sides , we get

Subtract 180 from both sides , we get

Divide both sides by 6, we get

or

Hence, the required value of x=10.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
