The answer is p , merry Christmas
Answer:
450 ounces
Step-by-step explanation:
We know that the cost of the mixture 
must be the cost of the everyday moisturizing lotion 
plus the cost of the self-tanning lotion 
, which means 
.
The cost of any substance will be the cost per ounce of the substance (c), multiplied by the number of ounces (n), which means C=nc, so we have from the previous formula that we have:
But we also know that the number of ounces of the mixture must be the sum of the number of ounces of the everyday moisturizing lotion with the number of ounces of the self-tanning lotion, so we have
We want to calculate the number of ounces of the self-tanning lotion (
), so we solve for that variable:
And substitute our values in this formula, to get:
Answer:
1) $8000
2) $1000
3) 8 months, since y represents our remaining amount to be paid, we set it equal to 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.
Step-by-step explanation:
We have the equation y = -1000x + 8000 which follows the linear equation:
y = mx + b, where m is our slope and b is our y-intercept
1) The initial balance can be found with our constant "b" which in this case is 8000. You can also plot the function of y and you will find that 8000 is the intercept when x = 0, aka the start
2) We can calculate the rate of change for when the loan is repaid by looking at the slope "m", in this case it is 1000. It subtracts 1000 each month, meaning $1000 is being payed and taken out of the bank account
3) To find how many months it will take for the loan to be repaid, let's solve for x when y = 0.
0 = -1000x + 8000
-8000 = -1000x
8 = x
It will take 8 months. Why? Since y represents our remaining amount to be paid, we set it = 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.
It would be 49
10+13=23
23+13=36
36+13=49
I think this is right
Answer:
x = 3/4 or x = 0.75
Step-by-step explanation:
y=2x²-3x+4
y'=4x-3 = 0
x = 3/4 .... answer
or
x = - b/2a ...y=ax²+bx+c
x = - (-3)/(2*2) = 3/4
