Answer:
a^2+4b^2+2a+4b
Step-by-step explanation:
(a +2b)2 + 4b² - a²
=2a+4b+4b^2+a^2
=a^2+4b^2+2a+4b
$349.30 because u multiply the cost of 1 case times 14 the # of cases
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
From the information given, she owes her parents a total of $1854.
She will take a period of 18 months to repay the whole loan.
We first find out the how much is each installment per month.
We divide the whole amount by 18 months so 1854/18 = $103
If she pays 103 dollars per month, then at one year (12 months) she would have paid: 103 × 12 = 1,236 dollars.
She would owe 1854 - 1236 = 618
There she would still be owing her parents $ 618 after one year.
-|x+3|
its a positive 3 because you move it the opposite way im pretty sure
and it’s negative because it’s pointed down
