Mikayla put $212 in a savings account at the beginning of the year. At the end of each month, she withdrew $12 from her account. Matthew put $30 in his savings account at the beginning of the
year. At the end of each month, he deposited $14 in his account. Let x represent the number of
months which have passed and y represent the amount in each savings account.
a. Write an equation to represent the amount in Mikayla's savings account.
b. Write an equation to represent the amount in Matthew's savings account.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

the answer would be  

a.

3: 1

step-by-step explanation:

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
