Hey there!

In this problem, we're looking for x's relation to y. We want to know what we multiply, divide, or do any other operation to on x to get y.

And that, is why we have algebra.

We take our x value, and we put a variable, z, after it. That allows us to solve for z and see what we are doing to x to get y.

Let's try one:

We have 2, and when it goes through our function, we get 16. We have:

2z = 16
z = 8

Next one:

3z = 24
z = 8

Finally:

4z = 32
z = 8

We see a common pattern. Y is just x multiplied by 8.

Therefore, your answer is B, y = 8x

Hope this helps!

Can you please help me answer this question what's a+3

Inessa [10]

Answer:

a+3

Step-by-step explanation:

You cannot go any further in answering this question. These two terms are not like terms so they cannot be combined. Therefore, the answer is just a+3 itself.

FIND THE AREA...!!!!!

I think C I’m not sure but if you want me to explain I multiplied 12 x 10 and 20 x 6 and they both equal 120. So then I added 120 + 120 and got 240. Then u just added 8 because 8 was never use. Which will now look like 240 + 8 and that equal 248. :)

In ΔUVW, the measure of ∠W=90°, VW = 32 feet, and WU = 78 feet. Find the measure of ∠V to the nearest degree.

DanielleElmas [232]

Answer: $67.68^{\circ}$

Step-by-step explanation:

Given

$\angle W=90^{\circ}$

$VW=32\ ft$

$WU=78\ ft$

from the figure, we can write

$\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}$

2 x 2√3 please! Thank you.

IceJOKER [234]

2 x 2 √ 3

You can multiple 2 by 2 because they both are outside numbers . But you can't multiple √3 because it is inside the radical.

So.. the answer is 4√3
