Step-by-step explanation:
-7 is bigger
Answer:
no, its less
Step-by-step explanation:
because in negatives the higher the number is (ex: -10) the less the value is, so its the opposite of positive numbers
The area of the square base is S(x), where x is the length of the concrete foundation, and the area of the base of the cylindrical tank is C ( r ), r is the radius of the cylindrical tank. What does the expression S ( C ( r ) ) represent?
Answer:
C(r) is the area of the base of a cylindrical tank with radius r.
We know that this area is:
C(r) = pi*r^2
S(x) is the area of the square base where x is the side length of the base.
S(x) = x*x
Now, we have the expression:
S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)
Now, we have a problem here.
In S(x), S(x) is in units of area, and x is in units of length.
And the same for C(r), C(r) is in units of area, and r in units of length.
then we can not have x = C(r)
Then this expression does not represent anything, because the units do not match, so it has no physical sense.

If an 8MB-mp3 music file player can store 3,780 songs. How many albums can a 16MB store if there are 12 songs on each album?
Answer:
Hey there!
8MB=3780 songs
16MB=3780(2), or 7560 songs.
If there are 12 songs per album, the 16MB music file can store 7560/12, or 630 albums.

(x - 9(a/8)) = a a = 16
Answer:
x = 34
Step-by-step explanation:
(x - 9(16/8)) = 16
(x - 9(2)) = 16 Divide 16 and 8
x - 18 = 16 Multiply 9 and 2
x = 34 Add 18 to both sides

Which choice correctly explains which product is the better buy? Coffee Brand A is sold for $6.99 per pound Coffee Brand B is sold for $5.69 for 12 ounces Question 1 options: A Coffee Brand A is a better buy because its unit rate is $2.29 per ounce B Coffee Brand A is a better buy because its unit rate is $0.44 per ounce C Coffee Brand B is a better buy because its unit rate is $2.11 per ounce D Coffee Brand B is a better buy because its unit rate is $0.47 per ounce.
Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.

Hello! I can help you! I did not know what numbers you needed so I worked on problems 43- 46. For problems 43 and 44 you are going to be doing the same thing, but I can show you have to do both. So for number 43, y=-4x-2; (0,-1), you want to keep it parallel, so you are going to keep the slope ( -4) the same. You use point slope form which is y-y1=m(x-x1) and you plug it in. So I used the points that they gave at the top (0,-1) which means 0 is x and -1 is y so my new equation in point slope is y+1=-4(x-0). I did y+1 instead of y-1 because two negatives make a positive so the negative 1 makes the equation positive. After I wrote the equation, I solved it by distributing the -4 to the numbers in the parentheses (x-0). I got y+1=-4x and from there I just subtracted 1 on both sides so all that’s left is y=-4x-1 and that’s the answer for 43. You would do the same thing for number 44 but instead of getting the question in slope form you need to get there. You would just subtract 2x on both sides and get -y=-2x-4 and from there you divide a negative 1 on both sides so that y is positive ( y is always positive) and your equation will be y=2x+4 and then you do the same thing you did for question 43 with the point slope information. For the next to problems, 45 and 46, it going to be a little different but it’s not too difficult. Instead of just taking the slope and plugging it into the point slope equation you need to flip the reciprocal and make it negative. So for 45, 2/3 would turn into -3/2 and that is what you would plug into the equation. It would be y+2=-3/2(x+6) and you would solve and get y+2=-3/2x-9 from there you would subtract 2 on both sides and you would get y=-3/2-11. You would do the same for number 46, except in the beginning you need to subtract 4x from both sides to get y=4x-6 and the just flip the reciprocal and make it negative ( -1/4x). I hope that helped you understand! Good luck! :)

Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
Infinitely many solutions.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
