Answer:

y = 3x+2

Step-by-step explanation:

Okay, so as x increases by 1, y increases by 3. If we subtract 1 from the x side and 3 from the y side, we get the y intercept, or b, as 2. This means the answer is the first option, but if you want to go further, you can find the change in y and x and determine the equation. It went from (0, 2) to (1, 5). The x changed by 1, and the y changed by 3. We know that slope is rise over run, so we can put it like 3/1, which equals 3. This means that the equation is y = 3x+2, so you are correct!

How do you find the lateral area of the prism

Lina20 [59]

Hi there!

The lateral area is the area of the figures connecting the bases. We have rectangles here. We'll need to find the area of each figure and add them together to find the lateral area.

WORK:
(2.8 x 12) + (8.1 x 12) + 2(4 x 12)
33.6 + 97.2 + 96
LA = 226.8 units^2

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

What is the value of the expression below?

timurjin [86]

Answer:

I don't see a correct answer. See below.

Step-by-step explanation:

Thanks for clarifying the question. But if 27√3 is the correct expression, I don't see an answer option that fits.

√3 = 1.732

27*(1.732) = 46.77

But all the answer options are whole numbers. The presence of√3 makes it difficult to find an expression that would result in a whole number. Expressions such as:

27/√9 = 9, or

√27/√3 = 3

would be more consistent with producing a whole number result.

I hope this helps.

A line that passes through the points (–4, 10) and (–1, 5) can be represented by the equation y = (x – 2). Which equations also

lyudmila [28]

The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line.
Let find the equation of the line:
First compute the slope using formula:
<span> </span> $\frac{y_2-y_1}{x_2-x_1}= \frac{5-10}{-1-(-4)}= \frac{-5}{3}$
So the equation is in the form:
$y=\frac{-5}{3}x+s\text{ wherein s is another parameter. }$
For x=-4 we get the equation:
$10=\frac{-5}{3}(-4)+s$
Solving the above equation for s we get:
$s= \frac{10}{3}$
The equation then is the following:
$y=\frac{-5}{3}x+\frac{10}{3}$

The correct answer then is equation 2 and equation 3.
