2/3x - 12, x=18 (show work)
Answers
Answer:
0
Step-by-step explanation:
Since we know x=18, we need to find 2/3 of 18.
Let's make 2/3 so that the denominator(bottom part of a fraction) is 18.
18 divided by three is six so we needs to times the top number, 2, by 6.
The fraction would now be 12/18. Now we needs to subtracts 12 which would become 0/18. This equals 0.
reduce 36/-24 to the standard form
Answers
Least form of =
Step-by-step explanation:
Reducing in standard form :
/* Finding HCF of 36 and 24 , we get
36 = 2×2×3×3
24 = 2×2×2×3
HCF (36,24) = 2×2×3 = 12
Now ,
Divide numerator and denominator by 12 , we get
-36/12/24/12
Therefore,
Least form of =-36/24= -3/2

If $(2x+5)(x-3)=14$, find the sum of the possible values of $x$.
Answers
Answer:
x = 1/4 ± 1/4√233
Step-by-step explanation:
(2x + 5)(x - 3) = 14
~Use FOIL on the left side
2x² - 6x + 5x - 15 = 14
~Combine like terms
2x² - x - 15 = 14
~Subtract 14 to both sides
2x² - x - 29 = 0
~Use the quadratic formula and simplify
x = 1/4 ± 1/4√233

Greta uses 2 ounces of pasta to make 2/9 of a serving of pasta. How many ounces of pasta are there per serving?
Answers
Answer:9 ounces
Step-by-step explanation:
So first you want to start off with what you know
2/9 of a swerving is 2 ounces of pasta
Which aslo lets you know 1/9 of a serving = 1 ounce of pasta
Since 1/9 of a serving is 1 ounce you want to times that by 9 to get a whole serving
1 * 9 = 9
So you know that 1 serving is 9 ounces of pasta

(graph, table, equation) = (1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)
Step-by-step explanation:
The graphs have the following (slope, intercept), so can be easily matched with the corresponding equation.
(1/2, 1), (2, -1), (1, 2), (1/2, -1), (-2, -1)
We can look at the points in the tables to see which graph they appear on.
Table 1, (-2, 3) is on graph 5
Table 2, (-3, -1) is on graph 3
Table 3, (-1, -3) is on graph 2
Table 4, (-2, -2) is on graph 4
Table 5, (4, 3) is on graph 1
__
Then our triples of graph, table, equation are ...
(1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)

Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 28, the sum of the squares is 65, and the sum of the cubes of the numbers is 407.
Answers
Answer:
Step-by-step explanation:
1) f(x) = x+y , xy = 49 --> f(x) = x+49/x
f '(x) = 1-49/x2 , x = ±√49 , choose x = +7
y = 49/x = 7
smaller = 7
larger = 7
2) Vertical Distance is difference between the two functions
V(x) = x+56 - x2, V '(x) = 1 -2x --> x = 1/2 --> V(1/2) = 56.25 <---Max Vertical distance
Boundary at -7 and 8 are less
3) I googled the equation, it is really y(n) = kn/(49+n2)
y '(n) = (k(49+n2) - 2kn2)/(49+n2) , Setting to zero, k(49+n2) -2kn2 = 0 , n = 7
4) Let x and y be the sides of the rectangle. A = xy = 37.5 Million or y = 37.5/x
The length of the fences is f(x) = 2x + 3y = 2x+112.5/x
f '(x) = 2-112.5/x2 --> x = √56.5 = 7.5 and y = 37.5/7.5 = 5 then scale by √Million
smaller = 5000 ft and larger = 7500 ft
this took me ages to work out so hopefully it helped
Answer:
x + y = 11
Step-by-step explanation:
xy = 28
x² + y² = 65
x³ + y³ = 407
(x + y)(x² - xy + y²) = x³ + y³
(x + y)(x² + y² - xy) = x³ + y³
(x + y)(65 - 28) = 407
37(x + y) = 407
x + y = 407÷37
x + y = 11
