The graph shows the function f(x)=4x+21 and g(x)=−(1/3)^x+4 +6 . what are the solutions of the equation 4x+21=−(1/3)^x+4 +6 ? x=−6 and x=−4 x=−6 and x=−5.75 x=−6 and x = 3 x = 3 and x=−5

x=−6 and x=−4

Step-by-step explanation:

The solutions to the equations are the coordinate points where the two functions intersect.

(-6,3) and (-4,-5)

The x values are -6 and -4.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

do you mean add both of the equations together

because if you do the answer is 10x-5
