Answer:
u = 5
Step-by-step explanation:
<u>→Distribute the 3 to (-3u - 5):</u>
4u = 16u - 9u - 15
<u>→Add like terms:</u>
4u = 7u - 15
<u>→Subtract 4u from both sides:</u>
0 = 3u - 15
<u>→Add 15 to both sides:</u>
15 = 3u
<u>→Divide both sides by 3:</u>
5 = u
For (A):
well, the first step for finding the proportional relationship between the amount of wet dog food and dry dog food would be finding the unit rate. Unit rate is basically "per one".
An example would be: (I'm making up numbers)
If there are 10 dry food cups and 15 wet food cups, you would divide 10 by itself because you are trying to find unit rate (whenever trying to find unit rate, always divide the number by itself to find one) . 'Unit' means one, but since you divided by 10 on that side, you have to do the same to the other side (in a table) so you divide 15 by 10 and get your answer. that's how you would find unit rate.
[1 (dry food) and 1.5 or 1 1/2 (wet food) would be your unit rate]
In your situation, you have different numbers. For the second row, you would divide six by itself, then do the same thing you did on other side (divide by six) I recomend using a calculator because its going to be in decimals, and might be small. That would be your unit rate. You use unit rate when you try to find out (like your problem) if its proportional, multiple choice question, see if its true or false, ect. When finding out unit rate, doesn't matter what row it is because you are trying to find out if its proportional or not. (I chose second row because its easier to do than first row. Third row also works too.)
Great, now you know unit rate.
To find out if its proportional, its a bit tricky to explain. Lets use the example we used earlier, and make it onto sentence form.
'For every 1 cup of dry dog food, there is 1.5 (or 1 1/2) cups of wet dog food'
Now try to make your unit rate that you got into sentence form. (It should be the same, only the numbers change) Now that we have it in sentence form, it should be easier to understand. If you raise the pieces of dry dog food (by multiplying any number you need to) the same applies to the wet dog food. If you had to find out how many cups of wet dog food are in 9 cups of dry dog food, you would multiply your unit rate by 9 (You always multiply the side that is 'one' or 'for every' by the number that you need, or it changes your answer.) Now try to make sense of it.
"For every 6 dry dog food cups, there are 2 wet dog food cups"
Is your math the same or different? Now try to sentence out the answer you got and see if they are different or same. If your answer and the row are matching, then that means they ARE proportional. If they are not matching, that means they are NOT proportional.
Hope this helped, I know its long but I hope I was still some sort of help xd if you have any questions you can ask me
For this case we have that by definition, the total surface area of a right prism is given by:
Where:
p: Perimeter of the base
h: It's the height
B: It is the area of the base
So:
So, we have:

Step-by-step explanation:
A right triangle is defined as a triangle with sides in the ratio 3:4:5. Pythagorean Doubles are triangles whose sides have had a ratio of the whole numbers as their sides. Even if the sides are multiplied by any number, the result is still a right triangle with sides in the ratio 3:4:5. For instance, 6, 8, and 10 are all numbers.
Answer:
(-4,0) and (0,0)
X=-2
Max
(-2,4)
Step-by-step explanation:
The zeros of a function are the x-intercepts. They are found where y=0 on the x-axis. This is where the function crosses the x-axis. They are written as (x,y). Here the zeros in #1 are (-4,0) and (0,0).
The axis of symmetry is the line that divides the parabola in half for a perfect reflection. It is written as x=a. Here it is x=-2. A quadratic has a max or min. This is either the highest or lowest value of the function. Here it is a max at (-2,4). The max or min is also the vertex.
