Start off calculating the total of the dog food Mimi and Honey eat together every day. Knowing 1/2 and 2/4 is the same it might help while adding up those numbers. That means they eat 3/4 + 2/4 = 1 1/4 can everyday. Multiply that by the total days, in this case 60, gives you 75 cans. You can only buy a 3-pack so dividing it by 3 gives you the total of packs she has to buy. That is in this case 25 packs. While every pack costs you $5 that means 25 packs will cost Chanel 25 x $5 = $125. Doing the same but for 29, 30 and 31 days instead of 60 should give you the answer to the last few questions.
Answer: y = 5x + 10
Step-by-step explanation:
y= 5x + 10
THINK ABOUT IT! if 5 is for EACH additional session and x is equal to the NUMBER OF SESSIONS...... then 5 times x will give you the cost for each additional session, but NOT INCLUDING THE 10 FOR THE FIRST SESSION. so simply just do 5x + 10 and y is the total cost so
y = 5x + 10
Given that the last term is -3x^4, the polynomila is ordered in descending order of the exponent of x. Then, the first term is that where y is with the highest exponent, that is y^4
Simplify the terms with y^4: -2y^4 + 6y^4 = 4y^4
Then the first term is 4y^4
