Please help I am stuck on this equation

Answer:

A. Reflection over the y-axis and rotation 90° counterclockwise

Answer:

The answer is A (:

Step-by-step explanation:

To solve for m in the equation (9 – 6i) × m = 9 – 6i, both sides are divided by (9 – 6i), yielding m = 1.

The equation given is (9 – 6i) × m = 9 – 6i. To find the value of m, we can divide both sides of the equation by (9 – 6i). Doing so, we get:

m = (9 – 6i) / (9 – 6i) = 1.

Therefore, the value of m is 1.

def: -in an isosceles triangle two of its angles measure the same

- the sum of all angles in a triangle is 180°

case1: if angle a measures the same with another angle in the triangle

=>angle1=56

angle2=180-2*56=180-112=68°

from this case we extract 2 posibilities:

B=56° or B=68°

case2: if the other 2 angles beside a measure the same

angle1=angle2=(180-56)/2=62°

from this case we e extract one posibility:

B=62°

Final answer:

In an isosceles triangle ABC with angle A equal to 56 degrees, three possible values for angle B are 68 degrees if it is the vertex angle, and 56 degrees or 62 degrees if it is one of the base angles.

Explanation:

If triangle ABC is an isosceles triangle with angle A (a) equal to 56 degrees, we can work out three possible values of angle B using the properties of an isosceles triangle and the fact that the sum of angles in any triangle is 180 degrees.

Since triangle ABC is isosceles, two of its angles are equal. If angle A is one of the two equal angles, then angle B (which is the vertex angle) is given by:

If angle B is one of the two equal angles, then we have two cases:

In the first case where angle B equals angle A (56 degrees), then the other base angle (angle C) must also be 56 degrees, and the remaining vertex angle B would be 180° - 56° - 56°, which is 68 degrees.

In the second case, where B is the vertex angle:

This gives us the same value for angle B as in the first case since both result in the same configuration.

Finally, if angle B is one of the two base angles and equal to angle C, then B would be (180° - A) / 2:

So, three possible values for angle B are 68 degrees, 56 degrees (if B is one of the base angles), and 62 degrees (again, if B is a base angle).

Answer:

A.)Line P, because it is closest to most data points

Step-by-step explanation:

The line of best fit is a line which best represents the data and the data points are closely related to it.

It is also known as a trend line.

The line of best fit may pass through, some , none or all of the data points.

Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.

Hence, by looking at the scatter plot we see that all the data points lie above Line R.

Hence, the Line R will not be a line of best fit.

But all the data points lie close to the line P , hence it act as a line of best fit.

Answer:

x = 4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

To solve, we need to isolate the variable, x by getting all the numbers to one sides and the variables to the other

8x-3=3x+17

Subtract 3x from both sides

8x-3x-3=3x-3x+17

5x-3=17

Add 3 to both sides

5x-3+3=17+3

5x=20

Divide both sides by 5

5x/5=20/5

Answer: [tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

Step-by-step explanation:

We are told [tex]a-b=2[/tex] being [tex]a[/tex] and [tex]b[/tex] positive integers, hence:

[tex]a=2+b[/tex] (1)

Now we have the following expression:

[tex]\frac{4^{0.5 a}}{2^{b}}[/tex] (2)

Which can be also written as:

[tex]\frac{2^{2(0.5 a)}}{2^{b}}[/tex] (3)

Since [tex]4=2^{2}[/tex]

Then, substituting (1) in (3):

[tex]\frac{2^{2(0.5(2+b))}}{2^{b}}[/tex] (4)

Since we have exponents with the same base, we can do the following:

[tex]\frac{2^{2+b}}{2^{b}}=2^{2+b} 2^{-b}[/tex] (5)

Finally:

[tex]2^{2+b} 2^{-b}=2^{2+b-b}=2^{2}=4[/tex] (6)

Hence:

[tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

x=(3,1/4)

Step-by-step explanation:

Be sure to use the formula...

[tex]-b + or - sqrt{b^{2} - 4ac } / 2a[/tex]

- First, move all variables to one side (left) of the equation. You want one side to be equivalent to zero.

-Next, you need to find a, b, and c. This should be...

a=4

b=-13

c=3

- Knowing this, fill in these variable to go along with the formula. I cannot do this for you, as you should try it on your own. But, you should end up with the solution x= (3,1/4).

- Hope this helps! If you need a further explanation or help on any more problems please let me know, as I would be glad to help anytime.

Answer:

r=6.5c-20

Step-by-step explanation:

The raw score is given by

r=c*6-0.5(40-c)

Taking the number of correct answers as c

The incorrect answers will be 40-c

Since each incorrect answer deducts 0.5 points. Then the deducted points will be 0.5(40-c)=20-0.5c

Since correct answers, c gives 6 points each then the number of points will be 6c

Now, the raw score will be

r=6c-(20-0.5c)

Opening the brackets, the signs change hence

r=6c-20+0.5c

r=6.5c-20

The formula that describes the student's raw score based on the number of correct answers is; r = 6.5c - 20

We are told that they gain 6 points for each correct answer and lose 0.5 points for each incorrect answer. Thus, the formula for the raw score is;

The raw score is given by

r = 6c - 0.5(40 - c)

where;

c is the number of correct answers

40 - c as number of incorrect answers

We are told that each incorrect answer deducts 0.5 points.

Thus, the deducted points = 0.5(40 - c) = 20 - 0.5c

We are told that each correct answers, c gives 6 points each. Thus, the raw score will be;

r = 6c - (20 - 0.5c)

⇒ r = 6c  - 20 + 0.5c

r = 6.5c - 20

Answer and Step-by-step explanation:

A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.

The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.

Hope this helps!

Answer:

A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).

They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.

Some examples:

2x+3y=15

x-3y=3

y=x^2+1

Final answer:

To find the length of KL in ΔKLM with a 90° angle at M and a 10° angle at K, we use the sine function with the given hypotenuse length of 86 feet. Calculating sin(10°) times 86 gives approximately 14.9296 feet, which rounds to 14.9 feet.

Explanation:

To find the length of KL to the nearest tenth of a foot in ΔKLM, where ∠M equals 90°, ∠K equals 10°, and LM is 86 feet, we can use trigonometry.

Since LM is the hypotenuse and we want to find KL, which is the side opposite ∠K, we will use the sine function:

Calculating this we get:

This provides us with the length of KL in the triangle.

Answer:

Soda- 156

Hot Dogs- 52

Step-by-step explanation:

Final answer:

The vendor sold 156 sodas and 52 hot dogs at the basketball game. This was determined by setting up a system of equations using the total number of items sold and the ratio of sodas to hot dogs, then solving for each.

Explanation:

To find the number of sodas and hot dogs sold at the basketball game, we can set up a system of equations based on the information provided:

Let S represent the number of sodas sold.

Let H represent the number of hot dogs sold.

The problem states two key pieces of information:

The total number of sodas and hot dogs sold is 208: S + H = 208.

The number of sodas sold was three times the number of hot dogs sold: S = 3H.

We can substitute the second equation into the first to solve for H:

3H + H = 208

4H = 208

H = 208 / 4

H = 52

Now that we have the number of hot dogs sold (52), we can find the number of sodas sold:

S = 3H

S = 3 \\( 52 \)

S = 156

The vendor sold 156 sodas and 52 hot dogs.

The value of m is [tex]-\frac83[/tex].

Step-by-step explanation:

If two vectors [tex]\vec A[/tex] and [tex]\vec B[/tex] are perpendicular to each other then their dot product will be zero i.e [tex]\vec A.\vec B=0[/tex]

If two vectors [tex]\vec A[/tex] and [tex]\vec B[/tex] are parallel to each other then their cross product will be zero i.e [tex]\vec A\times\vec B=\vec 0[/tex]

Given vectors are a= (3,4) and b=(m,2)

The position vector of [tex]\vec a[/tex]  is =[tex]3 \hat i+4\hat j[/tex]

The position vector of [tex]\vec b[/tex]  is =[tex]m \hat i+2\hat j[/tex]

Since [tex]\vec a[/tex] and [tex]\vec b[/tex] are perpendicular.

Then,

[tex]\vec a. \vec b=0[/tex]

[tex]\Rightarrow (3\hat i+4\hat j).(m\hat i+2 \hat j)=0[/tex]
