Answer:

-9yъ

Step-by-step explanation:

Since they have the same variables (yъ) then you can add or subtract,

=-8yъ -yъ

= -9yъ

[tex]\text{y}=6 \ \text{and} \ \text{z}=2\\\\\dfrac{3\text{y}-\text{z}}{\text{y}+5\text{z}}=\dfrac{3\cdot6-2}{6+5\cdot2}=\dfrac{18-2}{6+10}=\dfrac{16}{16}=\huge\boxed1[/tex]

Answer: Choice B

[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]

===============================================================

Explanation:

Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is

c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)

This represents the length of the vector <-4,7>

Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.

The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

An angle that is adjacent and congruent to m ∠FTK is, m ∠HTK. So option 1 is true.

Used the concept of angle that states,

An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

T lies on both FH and GJ.

Now by the given figure;

m ∠FTK = 90 degrees

Hence, an angle that is adjacent and congruent to m ∠FTK is,

m ∠HTK = 90 degrees

Therefore, option 1 is true.

Answer:

Let's take an example.

If you put the value of x as 1, it gives one.

Even if you put 3.997654, it will give 3.997654.

But for any negative real number, it gives the same number but not with it's negative sign. Like if x =-3/7,

It will give 3/7.

Answer:

a = -0.2cx^-1 + 1.7x^-1

Step-by-step explanation:

Solving for variable a.

Add "-c" to each side of the equation.

5ax + c + -c = 8.5 + -c

5ax = 8.5 - c

Divide each side by 5x.

a = 1.7X^-1 - 0.2cx^-1

Final answer:

a = -0.2cx^-1 + 1.7x^-1

The distance the car will travel in 20 revolutions of the wheel is 1507.96 inches.

Given that :

Radius of wheel , r = 12 inches

Number of revolutions = 20

The Circumference of the wheel = 2πr

Circumference of the wheel = 2 × π × 12 = 24π

The distance the car will travel after 12 revolutions of the wheel will be :

Number of revolutions × Circumference of wheel

20 × 24π = 480π = 1507.96 inches

Step-by-step explanation:

Since we are adding 3 to the x-coordinate and subtracting 1 from the y-coordinate, (-5, 2) becomes (-2, 1).

Answer:

(-5 2) = (x + 3, y - 1) (since point p is translated using the rule (x + 3, y - 1))

Comparing each axis,

-5 = x + 3

2 = y - 1

so for x axis:

x = -5 - 3

x = -8

Also, for y axis:

y = 2 + 1

y = 3.
