Write the conjugate of the following complex
number:
-6i
Answer:
[tex]6i[/tex]
Step-by-step explanation:
We want to write the conjugate of the complex number:
[tex]-6i[/tex]
Recall that the conjugate of a complex number in the form a + bi is a - bi, and vice versa.
We can rewrite our complex number as:
[tex]\displaystyle 0 - 6i[/tex]
Hence, a = 0 and b = 6.
Then its conjugate will be:
[tex]0 + 6i = 6i[/tex]
pat has no more then 20 sweets. she counts her sweets by twos she has one sweet left. then she counts by five. she has 2 left over. how many sweets could she have
Answer:
She can either have 7 sweets or 17 sweets.
Step-by-step explanation:
Variable x = number of sweets Pat has
x < 20
Counting by 5's (5, 10, 15) that will result in 2 left over (5 + 2, 10 + 2, and 15 + 2). This leaves 3 possible options as to how many sweets Pat has: 7, 12, and 17.
Counting by 2's (2, 4, 6 . . . 18) that will result in 1 left over (6 + 1, 10 + 1, 16 + 1) This leaves 2 possible options, given the other numbers from counting by 5's were eliminated.: 7 and 17.

-6x+5y=34
-6x-10y=4
Answer: x = -4
y = 2
Step-by-step explanation:
From equation I
-6x + 5y = 34
-6x = 34-5y
-(-6x) = -(34-5y)
or, 6x = 5y-34
or, x = 5y-34/6
so
substituting the value in equation II
-6x-10y = 4
or, -6{(5y-34)/6} - 10y = 4
or, -(5y-34)-10y = 4
or, -5y + 34-10y = 4
or, -15y = -30
or, y = -30/(-15)
so, y = 30/15
so, y = 2
now
x = (5y-34)/6
= (5*2-34)/6
= (10-34)/6
= -24/6
= -4
Answer:
x=-4, y=2
Step-by-step explanation:
-6x-10y=4
-6x=4+10y
(4+10y)+5y=34
15y=30
y=2
-6x-10(2)=4
-6x=24
x=-4

Answer:
66 = ∠JKN
Step-by-step explanation:
∠JKM = 99
∠LKM = 66
KN bisects means middle point divides into two equal parts
so first lets find ∠LKN and ∠NKM
66/2 = ∠LKN and ∠NKM each
33 = ∠LKN
33 = ∠NKM
so if we add ∠JKL + ∠LKN + ∠NKM = 99
∠JKL + ∠LKN + ∠NKM = 99
∠JKL + 33 + 33 = 99
∠JKL + 66 = 99
∠JKL = 99-66
∠JKL = 33
now to find ∠JKN we must add
∠JKL + ∠LKN = ∠JKN
33 + 33 = ∠JKN
66 = ∠JKN
The perimeter of a rectangle is 36 feet. The length is 2 feet more than 3 times the width. What are the dimensions of the rectangle?
Answer:
Step-by-step explanation:
The perimeter (P) of a rectangle is equal to the sum of twice the length and twice the width.
For this problem, let x be the width.
Then because the length is 2 less than 3 times the width
The length is 3x - 2
Therefore, P = 2x + (2)(3x - 2) = 36
Solving this for x gives:
2x + 6x - 4 = 36
8x - 4 = 36
8x = 40
x = 5
Therefore, the width = x = 5 feet
And the length = 3x - 2 = (3)(5) - 2 = 13 feet
yooo cuhh's is the square root of 64 a rational or irrational . ( and is it natural or a real number
Answer:
Step-by-step explanation:
It's an integer (which includes the minus number).
It can be a natural number (if the value of an expression comes to +/- 8 and for some reason - 8 is not permitted because it's a length)
It is for certain a real number.

Andrew bought four bottles of lemonade and two bottles of water for €2.45. From the same shop Michael
bought two bottles of lemonade and four bottles of water for €2.35. What is the total cost of one bottle of
lemonade and one bottle of water?
Answer:
0.8 euro
Step-by-step explanation:
Suppose the price of bottle of lemonade is x, when the bottle of water costs y.
Four bottles of lemonade cost 4x, two bottles of water cost 2y
4x+2y=2.45
Two bottles of lemonade cost 2x, four bottles of water cost 4y
2x+4y= 2.35
These equations( 4x+2y=2.45 and 2x+4y= 2.35) are simultaneous, so
multiply the first one by -2
-8x-4y=-4.9
-8x-4y+2x+4y= -4.9+2.35
-6x=-2.55
x=0.425 euro - the cost of bottle of lemonade
y=(2.45-4*0.425)/2
y=0.375 euro - the cost of bottle of water
0.425+0.375= 0.8 euro - the total cost of one bottle of
lemonade and one bottle of water
Answer:
price of lenonade bottle is 0.425
price of water bottle is 0.375
Step-by-step explanation:
In explaination, 'x' is the value of lemonade bottle and 'y' is the value of water bottle.
All explaination is in picture below.
Half the difference of a number n and 20 is 30. What is the number?
Answer:
80Step-by-step explanation:
Half the difference of a number n and 20 ⇒ (n - 20)/2... is 30 ⇒ = 30Solve the equation for n:
(n - 20)/2 = 30n - 20 = 30*2n - 20 = 60n = 60 + 20n = 80The number is 80
Answer:
Number is 40
Step-by-step explanation:
Let the number be n
(n - 20)/2 = 30
(n - 20) = 2 × 30
n = (2 × 30) + 20
n = 60 + 20
n = 80

Is (1, 10) a solution to this system of inequalities?
y > X + 9
y > 10
Answer:
No
Step-by-step explanation:
If (1, 10) is a solution to the system then it must satisfy both inequalities.
Using x = 1 and y = 10 , then
10 > 1 + 9 , that is
10 > 10 ← False
and
10 > 10 ← False
Neither of the inequalities are satisfied by (1, 10)
Thus it is not a solution

here is the table of values for y = f(x)
x -2 , -1 , 0, 1, 2 , 3, 4 , 5, 6
f(x) 5, 6, 7, 8, 9, 10, 11, 12, 13
mark the statements that are true
A. f (-1) =6
B. f (5) = - 2
C. The domain for (x) is the set (-2, -1, 0, 1 , 2, 3, 4, 5, 6
D. the range for f(x) is all real numbers
Answer:
A and C
Step-by-step explanation:
A
From the table the value of f(x) when x = - 1 is 6
Thus f(- 1) = 6 ← is true
B
From the table the value of f(x) when x = 5 is 12
Thus f(5) = - 2 ← is false
C
The domain is the values of x from the table ( the input values )
domain is { - 2, - 1, 0, 1, 2, 3, 4, 5, 6 } ← is true
D
The range is the values of f(x) from the table ( the output values
range is { 5, 6, 7, 8, 9, 10, 11, 12, 13 }
The range for f(x) is all real values ← is false
