Answer:
1.) 15-3-2=x
2.) He can buy 3 sodas
Step-by-step explanation:
1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)
2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3, he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.
The domain is all real numbers.
Let x = the amount of feet descended in 3 minutes (thus the total change of altitude of the balloon)
320 (feet per minute) / 1 (minute) = x (feet per minute) / 3 (minutes)
1) Divide: 320/1 = 320.
2) Multiply: 320 x 3= 960.
The balloon that descends at a rate of 320 feet/minute (so, every minute, it descends 320 feet) descends a total of 960 feet in 3 minutes.
The balloon's total change in altitude is -960<span>

Answer:
(-6,0)
Step-by-step explanation:
1) First step is to reflect across the x-axis. Since it's ON the x-axis, it's y coordinate stays the same (0).
2) Now to flip over the y-axis, which is easy to calculate. As we can see it's "6" coordinate is what we need to change to "-6".
