The total weight of the items Mikaila brought to the recycling center is 992.
This one is pretty simple. You have to look at the zeros given to you and you just have to plug it in for X. For the first function, (X+3(X+4), you replace the Xs so it would look something like this. (3+3)(-4+4). When you solve for both of these you will get 6 and 0. Because they both do not equal out to zero, this function does not work. If you do that to the rest of the functions, you will find that (X-3)(X+4) will equal out to 0 for both. You then know that this is the function. You can make sure that that is the correct answer by plugging the zeros into the other functions as well. If you do so, you will find that the other functions do not work.
A dilation has a scale of 4. This describes an EXPANSION type of dilation.
The scale of 4 means that the dilated image is 4 times bigger than the original image. The dilated image still retained the same proportion of the original image even though it is in a larger scale.
Just take the number of blocks there are and divide them amongst the number of people sharing the blocks.
For 5 people sharing 2 blocks:
2/5
For 6 people sharing 5 blocks:
5/6
Answer:
Step-by-step explanation:
Fie distanța totală = x
Un călător parcurge un drum în trei zile
În prima zi merge o treime din drum și încă 15 km
= 1 / 3x + 15km
A doua zi călătorește două șapte din restul
= 2 / 7x
În a treia zi
75 km
Cât de lung este drumul
= 1 / 3x + 15 + 75 + 2/7 (2 / 3x).
