Answer:

The correct choice is option C. -7/5 + 11/5i

Step-by-step explanation:

  3 + 5i / 1 - 2i

= (3 × 1 + 5 (-2)) + (5 × 1 - 3(-2)) / 1^2 + (-2)^2

= -7 + 11i / 5

= -7/5 + 11/5i

Answer:

option C. -7/5 + 11/5i

Answer:

640/20 is 32

hope it's helpful

When the number 640 is divided by the number 20, the result is 32.

To divide 640 by 20, we perform long division or use the concept of division as the inverse of multiplication. By dividing 640 by 20, we are essentially finding how many times 20 can be evenly divided into 640.

On Dividing 640 by 20 yields a quotient of 32. This means that 20 can be divided into 640 exactly 32 times, without any remainder.

Thus, 640 divided by 20 is equal to 32. In simpler terms, if we distribute 640 items into 20 groups, each group will contain 32 items.

Sum: x + (x + 18) + 2x = 26 ↔ x = 2

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

Hi there!

[tex]-2^2(-5x+10)=100[/tex]

Solve -2^2:

[tex]-4(-5x+10)=100[/tex]

Divide both sides by -4:

[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]

Subtract 10 from both sides:

[tex]-5x+10-10=-25-10\\-5x=-35[/tex]

Divide both sides by -5:

[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]

Therefore, x = 7.

Answer:

-2 to 2

Step-by-step explanation:

see there's the sign of absolute value around x

so even if we put a negative number in place of x we'll get a positive outcome.

for example,

|x| = 4

|x| = 3

and so on

so the actual domain of |x| reduces to => 0 to 4.

as you'll get the values of |x| in between 0 and 4 throughout -4 to 4.

where the smallest value is 0 and largest is 4.

for range,

I'll just put these smallest and largest values in place of x and solve for domain

y= |0| - 2

y = -2

y = |4| - 2

y= 4 - 2

y = 2

so, the range of the function becomes -2 to 2.

Answer:

x = 3/4 n

Step-by-step explanation:

-3(x+n)=x

Distribute

-3x-3n = x

Add 3x to each side

-3x-3n+3x= x+3x

3n = 4x

Divide by 4

3/4n = 3x/3

3/4 n = x

The given parameters include;

The following algebraic equation will be set to calculate the number of days the book was late before it was returned;

[tex]0.25(4) + (x - 4)0.3 = 40\\\\[/tex]

simplify the equation as follows;

[tex]1 + 0.3x - 1.2 = 4\\\\[/tex]

collect similar terms together;

[tex]0.3x = 4.2\\\\[/tex]

divide through by 0.3

[tex]x = \frac{4.2}{0.3} \\\\x = 14 \ days[/tex]

Thus, the number of days the book was late is 14 days.

Find how many days late was her book

The total days late is 14 days

charges per day for first 4 days = $0.25

charges per day for the remaining days = $0.30

Total amount Annika paid = $4.00

let x = number of days of the remaining days

Amount paid for first 4 days = $0.25 × 4

= $1

Amount paid for remaining days = 0.30 × x

= 0.30x

Total amount paid = Amount paid for first 4 days + amount paid for remaining days

4 = 1 + 0.30x

4 - 1 = 0.30x

3 = 0.30x

x = 3/0.30

x = 10 days

Total days late = 4 days + 10 days

= 14 days

The solution for the given expression is: [tex]\frac{-1+ i*\sqrt{19} }{2}[/tex] and [tex]\frac{-1- i*\sqrt{19} }{2}[/tex].

The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

For solving a quadratic function you should find the discriminant: D=b²-4ac and after that use this variable in the formula: [tex]x=\frac{-b\pm \sqrt{D} }{2a}[/tex]

The properties of multiplication are:

Here, you should apply the distributive property for solving this expression.

x*(2x)+2*(x+5) = 2x²+2x+10

After that, you should solve the previous quadratic equation.

D=b²-4ac=4-4*2*10=4-80= -76

Then,

[tex]x_{1,2}=\frac{-2\pm \sqrt{-76} }{2*2}=\frac{-2\pm i*\sqrt{76} }{4}=\frac{-2\pm i*2\sqrt{19} }{4}=\frac{-1\pm i*\sqrt{19} }{2}[/tex]

Answer:

Range = 5

Mode = 7

Step-by-step explanation:

To find range we first need to find the highest number and the lowest number

3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8

least number = 3

highest number = 8

now substract the lowest number from the highest to get the range

= 8-3

= 5

range = 5

Mode : the most common number in the list will be our mode

7 is our mode as it came 5 time in the list
