Examine the system of equations. y = negative one-half x + 1 y = 2x + 6 Use substitution to solve for x and

x =  - 2 , y = 2

( - 2, 2)

Step-by-step explanation:

first  equation add 1/2 to both  sides

second  equation subtract  2x  from   both sides

Solve the  first  equation

subtract x/2 from  both sides

substitute    for  y in  the  other  equation

add  

to  2x

subtract  1 from  both  sides

divide  both sides  by  

 x =  - 2

substitute  the  value of  x  into  an  equation

distribute

y = 1 + 1

y = 2

x = -2, y = 2

( - 2,  2)

x=-2 y=2

Step-by-step explanation:

it is -2,2 as the other thing

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
