Answer:

z = -4 + 6i

Step-by-step explanation:

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x+y is x−y . We can also say that x+y is a conjugate of x−y . In other words, the two binomials are conjugates of each other.

Answer:

I think the answer is either B or D

Step-by-step explanation:

Let's see

So they are Linear pairs

Option B

Answer:

-14 + 28 + 27

Step-by-step explanation:

well 42-27-28 is -14 so add -14 to 28 27 and you might get 42

Look up to their vertexes

So

[tex]\\ \rm\rightarrowtail g(x)=f(x)+k[/tex]

[tex]\\ \rm\rightarrowtail g(-3)=f(-3)+k[/tex]

[tex]\\ \rm\rightarrowtail 1=-3+k[/tex]

[tex]\\ \rm\rightarrowtail k=1+3[/tex]

[tex]\\ \rm\rightarrowtail k=4[/tex]

The required value of K for the transformation of f(x) is 4. Option C is correct.

Given that,
Graph for the transformation of f(x) in the format g(x) = f(x) + k,
To determine the k value.
Two parabolas open up with f(x) passing through (- 3, - 3)and g(x) passing through  (-3, 1).

A parabola is a cross section cut out of the cone and represented by an equation

Here,
Since equation of transformation is g(x) = f(x) + k
Now put the values of the vertex in the transformation equation,
f(x) passing through (- 3, - 3)and g(x) passing through  (-3, 1).

f(-3) = -3
g(-3) = 1
g(-3) = f(-3) + k
1 = -3 + k
k = 1 + 3

k = 4

Thus, the required value of K for the transformation of f(x) is 4. Option C is correct.

Step-by-step explanation:

A for loop basically relies on repeating the same code for a pre-set number of times. During which you can make any code repeat inside of it, including indexing through a type of list. Many times a for-loop will use the indexes in a list to calculate the number of times that the loop has to repeat. This is usually done in order to search or apply changes in an array of other types of data structures that have countless values stored in it.

Answer:

11 and 12 or -11 and -12

Step-by-step explanation:

If the side length of an equilateral triangle is 5 centimeters, the length of altitude is about 4.33 centimeters.

An equilateral triangle can be defined as a type of triangle or regular polygon that has equal side lengths and all of its interior angles are equal.

Mathematically, the length of altitude of an equilateral triangle is calculated by using this formula:

[tex]L=\frac{\sqrt{3} }{2} a[/tex]

Where:

Given the following data:

Substituting the given parameters into the formula, we have;

[tex]L=\frac{\sqrt{3} }{2} \times 5\\\\L=\frac{5\sqrt{3} }{2}[/tex]

Length = 4.33 centimeters.

Answer:

Student ticket=$10. Senior ticket=$7

Step-by-step explanation:

If we say Student ticket price = Y. and senior ticket price = X. Then we can say:

[tex]3x+5y=71\\10x+12y=190[/tex]

We can rewrite one of the equations as y equals:

[tex]10x=190-12y[/tex]

Then, we simply solve for x.

[tex]\frac{10x=190-12y}{10}=x=19-1.2y[/tex]

Then, we use the other equation and replace x with the equation we just solved

[tex]3(19-1.2y)+5y=71\\[/tex]

We simplify and it becomes:

[tex]57-3.6y+5y=71[/tex]

Then we subtract 57 from each side and get:

[tex]-3.6y+5y=-14[/tex]

Next, we combine the y and get:

[tex]1.4y=14[/tex]

Then we divide by 1.4 and get:

[tex]\frac{1.4y=14}{1.4} =y=10[/tex]

This means that the cost per student ticket is $10

Next we replace the y value in an equation with 10 and solve:

[tex]3x+5y=71\\3x+5(10)=71\\3x+50=71\\[/tex]

Then we subtract 50 from each side:

[tex]3x+50=71\\-50\\3x=21[/tex]

Finally, we divide each side by 3:

[tex]\frac{3x=21}{3} =x=7[/tex]

This means that each senior ticket costs $7

[tex]\mathrm{Simplify}[/tex]

[tex]-x=-15[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-1[/tex]

[tex]\frac{-x}{-1}=\frac{-15}{-1}[/tex]

[tex]Simplify[/tex]

[tex]x=15[/tex]

Answer:

Okay so yes the answer is 15

Step-by-step explanation:

It begins with 4X11 which is 44

So the equation becomes 44-x+4=33

Then I add 44 plus 4 which is me adding all the available terms which is 48

Then I subtracted 33 from 48 to find the value of x

And 48-33=15

So there you pretty much have it.

To be sure you can plug the answer in.

4x11=44

44-(x) which is 15 so 44-15=29

29+4=33

There ya have it!

The answer is 2000kg

Answer:

The original price is $50. The student's mistake in the equation is that he should have done 7.5/0.15

The student should not have multiplied, instead divided. He also didn't put 15 in a decimal form, which would have messed the whole equation up.

Answer:

The student should have divided the discounted amount by the percent. The percent should have been written as a decimal.
