2. If Greg drove 135miles in 3 hours, we must divide the number of miles by the number of hours to determine how many miles per hour he traveled:
135/3= 45mph
3. If she is payed $45 for 5 hours, we must divide the amount of money by the number of hours to find how much money she made per hour:
45/5= 9 dollars per hour
4. if she payed $0.72 for 8 ounces of water, we must divide the cost by the number of ounces to find out how much they spent per ounce:
.72/8= .09 dollars per ounce or 9 cents
1. The answer will be less than one. We know this because a positive number that is multiplied by a negative number will always equal a negative number and therefore be less than one.
Answer:
The formation of the equation is odd, but I assume it's supposed to be:
4k - 10k = -8k
-6k = -8k
-6k + 8k = -8k + 8k
2k = 0
=
k = 0
Answer:
p(x - 4) = x³ - 12x² + 48x - 69
Step-by-step explanation:
To evaluate p(x - 4), substitute a = x - 4 into p(a), that is
p(x - 4) = (x - 4)³ - 5
= (x - 4)(x - 4)(x - 4) - 5 ← expand 2nd/ 3rd factors using FOIL
= (x - 4)(x² - 8x + 16) - 5 ← distribute parenthesis
= x³ - 8x² + 16x - 4x² + 32x - 64 - 5 ← collect like terms
= x³ - 12x² + 48x - 69
Answer: $225
Step-by-step explanation:
Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2
Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

Here we need to write a function that models each variation, so we know that:
We also know that z varies directly with x and inversely with the product of r² and y. In other words, we can write z as follows:
Therefore, the model is:
