Which of the following best describes the expression 3x + 2y + 8z?
Gwar [14]
The expression above is composed of 3 terms which are: 3x, 2y, and 8z. All of the terms are the product of two items. The first term is a product of 3 and x. The second is a product of 2 and y. Lastly, the third is a product of 8 and z. 

<span>Thus, the expression is a sum of three products and there are only three terms. This answer is the second among the four choices.

hope this helps    :    )

Please help! Have had 10 attempts and still haven't got it!
adell [148]

Answer:

28

Step-by-step explanation:

To find the area of the shaded region, you have to start off with the area of the whole triangle. To find that, you multiply the height and length. length=10 height=8 (10x8=80). Then, since it's a triangle, you have to divide it by two (80/2=40). So, 40 is the area of the whole triangle. Then, you find the area of the white region, which is 12 (3x4=12). Finally, you take the area of the white square and subtract it from the area of the whole triangle (80-12=28). You would get 28.

What equation best models this data? (Use y to represent the population in millions, and t to represent the year, assuming that
lapo4ka [179]

Answer:

y = 2.31x + 309.35

Step-by-step explanation:

Whenever you are checking for a best fitting equation you want to check if it has a constant slope.  If it does then the relation is linear and super easy.

So, since the t values are increasing by the same amount you want to see if the y values are  too.  And they are, each population entry is increasing by 2.31, this is the slope.  

Also, keep in mind you can caluclate slope with the equation \frac{y_2-y_1}{x_2-x_1}  here x is replaced by t though.

Now, since we know it's linear and we know the slope we can find the equation with the formula  y - y1 = m(x - x1) where again, x is replaced by t and m is the slope 2.31

I am just going to use the first point.  so x1 = t1 = 0

y - 309.35 = 2.31(x-0)

y = 2.31x + 309.35

Let me know if there was something you didn't understand.
