Answer:
Linear Equation 1 — 3xyz
Linear Equation 2 — x = 4 and y = 2
Linear Equation 3 — x = 1 and y = (-1)
Step-by-step explanation:
(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.
The required result must be 3xyz.
(Linear Equation 2)
2x − y = 6 ....(1)
x − y = 2 ....(2)
Equation(2)−Equation(1) we get
x − y − 2x + by = 2 − 6
(−x) = (−4)
x = 4
Substitute x = 4 in (1) we get
2x − y = 6
2*4 − y = 6
8 − y = 6
(−y) = 6 − 8
y=2
(Linear Equation 3)
ax + by = a − b .......... (1)
bx − ay = a + b .......... (2)
Multiply equation (1) with a and equation (2) with b ,
a²x + aby = a² − ab ..........(3)
b²x − aby = ab + b² ......... (4)
Adding (3) and (4), we get,
(a² + b²)x = a² + b²
x = 1
Now, from (1),
ax + by = a − b
a + by = a − b
by = (−b)
y = (−1)
Hope my answer helps you ✌️

If you invest $550.00 at a 4% interest rate, what will be the interest?
rite an addition equation to show how you decomposed
7/6
.
Answer:
For the fraction model, fill the whole left bar, and only 1 in the right bar.
The addition equation is:
⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ = 7/6
Explanation:
Since the bar is divided into sixths (1/6 each), just count by 1/6 each time you fill each one and use the equation to represent the process.

Step-by-step explanation:
The felt costs 9¢ per square inch. She will only pay for the felt used to cover the box, even if there is waste or extra. How much money did Hazel spend on the felt? (1 point)
a
$18.18
b
$27.72
c
$36.36
d
$45.54
Answer:
C. $36.36
Step-by-step explanation:
You need to find the surface area of the box. Then, calculate how much it will cost.
SA = 2(wl + hl + hw)
SA = 2([11*8] + [6*8] + [6*11])
SA = 2(88 + 48 + 66)
SA = 2(202)
SA = 404 inches
9 cents per inch
0.09*404 = 36.36

There are many cylinders with a height of 18 meters. Let r
Represent the radius in meters and v represent the volume in cubic meters.
Complete he equation that represents the volume v as a function of the radius r.
Complete the table:
Answer: 18, 72, 288
Step-by-step explanation:
The formula for cylinder volume is V=π r^2 h
Substitute: radius =1 and height =18
V= 18 pi
radius=2
V=72 pi
radius=4
V= 288 pi
Of course, pi appears to already be written there for you :)
Hope this helps!

Solve each function for the given value.
Equation Given Value
Solution
a.) y = 15x - 50
when x = 7
b.) y = 1/2x + 20
when x = 50
c.) y = (3x)2 - 36
when x = 3
d.) y = 2.5x + 3.8
when x = 0.66
Answer:
a) y = 55
b) y = 45
c) y = -18
d) y = 5.45
Step-by-step explanation:
y = 15x - 50 when x = 7
y = 15(7) - 50
y = 105 - 50
y = 55
y = 1/2x + 20 when x = 50
y = 1/2(50) + 20
y = 25 + 20
y = 45
y = (3x)2 - 36 when x = 3
y = (3(3))(2) - 36
y = 9(2) - 36
y = 18 - 36
y = -18
y = 2.5x + 3.8 when x = 0.66
y = 2.5(0.66) + 3.8
y = 1.65 + 3.8
y = 5.45

.
∠1 and ∠2 are supplementary.
m∠1=124°
m∠2=(2x+4)°
What is the value of x?
Options:
13
26
40
36
41
Answer:26
Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.
On this note;
Sum of 1 and 2 is;
180 = 124 + (2x + 4)°
(2x + 4)° = 180 -124
2x = 56 -4
2x = 52
x = 26°.

I don't really understand this question.
Answer:
a) 3/2 or 1 1/2
b) 5/3 or 1 2/3
Step-by-step explanation:
1/2 + 1/2 + 1/2 =
3 x 1/2 =
3/2 or 1 1/2
1/3 + 1/3 + 1/3 + 1/3 + 1/3 =
5 x 1/3 =
5/3 or 1 2/3
Answer: (a) 1 1/2 and (b) 1 2/3
Step-by-step explanation: (a) 1/2 + 1/2 + 1/2 = 1/2 x 3
= 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).
Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)
(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
= 5/3
mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me
Answer:
75°
Step-by-step explanation:
Even if a triangle is translated, the original shape stays the same.
So, to get the answer, first add the first two angles of the triangle:
60 + 45 = 105
Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:
180 - 105 = 75.
So, you get 75°.
