A student usually saves $ 20 $20 a month. He would like to reach a goal of saving $ 350 $350 in 12 12 months. The student writes the equation 350 = 12 ( x + 20 ) 350=12(x+20) to represent this situation. Solve the equation for x x. ​ • Show your work or explain your answer. ​• Write your answer as a sentence that describes what the variable x x represents. ​ Enter your answers and your work or explanation in the box provided.

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.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
