What is the difference of 12-5i and -3 + 4i

Given problem:

 What is 9*5;

 The formula P*Q  = P x Q  - 7;

To  find 9*5, simply make P = 9 and Q = 5

Input into the equation and solve;

   P*Q  = P x Q  - 7    =   9 x 5 - 7

                                 = 45 - 7

                                 = 38

The solution to this problem is 38.

Given:

Four equations are

[tex] 7 x + 1 = 7 x+ 1[/tex]

[tex]3 x + 2 = 3 x-2[/tex]

[tex]4 x + 1 = 3 x + 8[/tex]

[tex]-2x-1 = -2 x-1[/tex]

To find:

Without solving which equation has no solution.

Solution:

We know that, in an equation

1. No solution : When variable terms are same but constants are different.

2. Unique solution : When variable terms are different.

3. infinitely many solution : When variable terms and constants are same.

In first and fourth equations, terms on left sides are equal to the terms on the right side. So, LHS = RHS for any value of x.

Therefore, these two equations (first and fourth) have infinitely many solutions.

In second equation, variable terms are same on both sides, but the constants are difference. So, LHS ≠ RHS for any value of x.

Therefore, the second has no solutions.

In third equation, coefficient of x are difference on both sides.

So, this equation has unique solution.

Therefore, Jubal's equations [tex]3 x + 2 = 3 x-2[/tex] has no solution. Hence, the correct option is B.

Answer:

D

Step-by-step explanation:

Step-by-step explanation:

Let's make the number we're finding to be [tex]a[/tex]. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be [tex]\frac{a}{4} +12\\[/tex]. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be [tex]\frac{a}{3} -5\\[/tex]. Since they are the same, we have the equation below.

[tex]\frac{a}{4} +12 = \frac{a}{3} -5\\[/tex]

All we have to do now is to find [tex]a[/tex].

[tex]\frac{a}{4} +12 = \frac{a}{3} -5 \\ \frac{a +48}{4} = \frac{a -15}{3} \\ (3)(a +48) = (a - 15)(4) \\ 3a +144 = 4a -60 \\ (60 -3a) + 3a +144 = 4a -60 +(60 -3a) \\ a = 204[/tex]

Our number must be [tex]204[/tex]. I think

the answer is 3/5

if that's not right I apologize

Answer:

3/5

Step-by-step explanation:

When dividing fractions, you change the division sign to multiplication and also flip the fraction that you are multiplying with.

So: 2/4 would become 4/2

3/10 x 4/2

12/20

Highest common factor between 12 and 20 is 4.

Divide both sided by 4:

Answer:

Larger number = 11

Smaller number = 6

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x - y = 5

3y + 4 = 2x       Subtract 2x

-2x + 3y + 4 = 0

===========

Multiply  the first equation by 2. Write the second equation underneath

2x - 2y = 10

-2x + 3y + 4 = 0

add

y + 4 = 10  

Subtract from both sides

y = 10 - 4

y = 6

==========

x - y = 5

x - 6 = 5                Add 6 to both sides

x = 5 + 6

x = 11

Answer:

Step-by-step explanation:

x       ← the smaller number

x+5    ←  five more than the smaller number - the larger number

3x    ← three times the  smaller number

3x+4   ← four more than three times the  smaller number

2(x+5)   ← twice the larger number

3x + 4 = 2(x + 5)

3x + 4 = 2x + 10

   -4         -4

     3x = 2x + 6

  -2x       -2x

      x  =  6

x+5 = 6 + 5 = 11

Check:   3•6 + 4 = 22;  22:2 = 11

Step-by-step explanation:

10x - 15 = 25

Answer:

y-9=-1(x+3)

Step-by-step explanation:

The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation

Answer:

7.alternate interior

x=64

8. same side interior

x=12

same side exterior

x=12

Answer:

Step-by-step explanation:

7. alternate angle or opposite angle are equal

   128 = 2x

    x = 128 / 2

    x = 64

8.  interior angles = 180

    180 = 72 + (7x + 24)

    180 - 72 - 24 = 7x

     x = 84 / 7

     x = 12

9.   same side angle = 180

     180 = 65 + (11x - 17)

     180 - 65 + 17 = 11x

     x = 132 / 11

     x = 12

Answer:

You can't solve this unless you have the amount of the other alloy.

Step-by-step explanation:

For example, the question should be something like:

A jeweler is using 10 pounds of alloy that is 2% platinum. He has another alloy that is 5% platinum. He wishes to combine these mixtures to form a mixture that is 3% platinum. How many pounds of the second alloy should be added to the first to get a mixture that is 3% platinum?

The line with slope m that contains the point (x1, y1) can be described by the equation

y − y1 = m(x − x1). In a real-world linear situation, you may have information that represents two points on the line. You can write an equation in point-slope form that represents the situation and use that equation to solve a problem.

Let x represent the number of days since the ship left port and y represent the number of gallons of water.

Two points on the line are (8,3240) and (1, 3555).

m =  

3555 − 3240

1 − 8

 =  

315

−7

 = −45

y − y1 = m(x − x1) Point-slope form.

y − 3555 = −45(x − 1) or y − 3240 = −45(x − 8)

y − 3555 = −45(60 − 1) Substitute for x.

y − 3555 = −2655 Simplify the right side.

y = 900 Solve for y.

900 gallons of water will be left after 60 days.

Hope this helped! (I didn't do it sooner cause I just did the quiz lol)

The equation of the function, in point-slope form, is given by:

[tex]y - 3555 = -45(x - 1)[/tex]

The amount of water left in the ship after 60 days is of 900 cubic units.

A line, in point-slope form, is represented by the following equation:

[tex]y - y_0 = m(x - x_0)[/tex]

In which:

We have two points: (1, 3555) and (8,3240).

[tex]m = \frac{3240 - 3555}{8 - 1} = -45[/tex]

Then

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 3555 = -45(x - 1)[/tex]

The amount after 60 days is y when x = 60, thus:

[tex]y - 3555 = -45(60 - 1)[/tex]

[tex]y = 900[/tex]

The amount of water left in the ship after 60 days is of 900 cubic units.

Answer:

I believe its 8.8.

Step-by-step explanation:

What I did was divide 53 by 6.

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.

Answer:

thirteen hundredths=13/100

one hundred thirty thousandths=130/1000

cancelling by 10 this is =13/100

hence the question

Step-by-step explanation:

13/100 is equivalent to 130/1000 because if you simplify 130/1000 it becomes 13/100.

You simplify 130/1000 by dividing both sides by 10. 130 divided by 10 is 13, and 1000 divided by 10 is 100.
