How do you find the y- intercept of a line? please explain by using the example above.

Answer:

Step-by-step explanation:

(2x - 6) + 4(x - 3)         use the distributive property a(b + c) = ab + ac

= 2x - 6 + (4)(x) + (4)(-3)

= 2x - 6 + 4x - 12        combine like terms

= (2x + 4x) + (-6 - 12)

= 6x - 18

9÷3=3

Answer:

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

Step-by-step explanation:

Let [tex]AB[/tex] a line segment in which [tex]M[/tex] is the midpoint. If both [tex]A[/tex] and [tex]M[/tex] are given, then we determine the location of [tex]B[/tex] from definition of midpoint. That is:

[tex]\frac{1}{2}\cdot \vec A + \frac{1}{2}\cdot \vec B = \vec M[/tex] (Eq. 1)

Where:

[tex]\vec A[/tex], [tex]\vec B[/tex] - Endpoints with respect to origin, dimensionless.

[tex]\vec M[/tex] - Midpoint with respect to origin, dimensionless.

[tex]\vec A + \vec B = 2\cdot \vec M[/tex]

[tex]\vec B = 2\cdot \vec M - \vec A[/tex]

If we know that [tex]A(x, y) = \left(x+6,\frac{1}{3}\cdot y \right)[/tex] and [tex]M(x, y) = (2,-5)[/tex], then the coordinates of [tex]\vec B[/tex] are:

[tex]\vec B = 2\cdot (2,-5)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = (4,-10)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex]

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

Complete question :

A reporter determines a baseball player's batting average, which is a ratio of number of hits to the number of times at bats. The result shown on a calculator as 0.2121....

How many hits would the player be expected to get in 200 at bats? Explain

Answer:

42

Step-by-step explanation:

Given that:

Batting average = number of hits / number of time at bats

Batting average obtained = 0.2121...

If at bats of the player = 200

Hence, number of hits ;

Batting average = number of hits / number of time at bats

0.2121 = number of hits / 200

Number of hits = 0.2121 * 200

Number of hits = 42.42..

= 42 ( approx)

The trigonometric function gives the ratio of different sides of a triangle. The option that is not an example of trigonometric reciprocals of sine, cosine, and tangent is theorem.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

The trigonometric reciprocal of sine, cosine, and tangent are cosecant, secant, and cotangent, respectively. Therefore, the option that is not an example of trigonometric reciprocals of sine, cosine, and tangent is theorem.

Answer:

a. (0,-6) and (8,0)

b. [tex]m = 3/4[/tex]

c. [tex]y = 3x/4 - 6[/tex]

Step-by-step explanation:

Given

[tex]3x - 4y = 24[/tex]

Solving (a): Two solutions

To determine the solutions of the equation, we assume values for x and y.

First: Let, x = 0

Substitute 0 for x in the equation

[tex]3x - 4y = 24[/tex]

[tex]3(0) - 4y = 24[/tex]

[tex]- 4y = 24[/tex]

Divide  both sides by -4

[tex]y = 24/-4[/tex]

[tex]y = -6[/tex]

So, one solution is (0,-6)

To determine another solution, we assume that y = 0

Substitute 0 for y in the equation

[tex]3x - 4y = 24[/tex]

[tex]3x -4(0) = 24[/tex]

[tex]3x = 24[/tex]

Divide both sides by 3

[tex]x = 24/3[/tex]

[tex]x = 8[/tex]

So, another solution is (8,0)

Solving (b): The slope of the equation

We have to get the equation in the form: [tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

[tex]3x - 4y = 24[/tex]

Subtract 3x from both sides

[tex]3x - 3x - 4y = 24 - 3x[/tex]

[tex]- 4y = 24 - 3x[/tex]

Divide both sides by -4

[tex]y = 24/-4 - 3x/-4[/tex]

[tex]y = -6 + 3x/4[/tex]

[tex]y = 3x/4 - 6[/tex]

By comparison,

[tex]m = 3/4[/tex]

Hence:

[tex]Slope = 3/4[/tex]

Solving (c): Slope intercept form

This has been solved in (b) above

[tex]y = 3x/4 - 6[/tex]

Answer:

m<A=76

m<BCD=105

Step-by-step explanation:

in a triangle, all of the angles add up to 180. so m<a=76 degrees

BCA and BCD are supplementary angles which means they add up to 180, so m<BCD=105 degrees

Answer:

human skin is thicker than sand , hope this helps

It will take 5 grains of sand to match the thickness of a human's skin.

Comparing numbers in maths defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, Human skin has a thickness of about 5×10⁻³ meter. A grain of sand has a thickness of about 1×10⁻³ meter.

As we can see the that the measurement of sand grain is greater than that of human skin's measurement, the skin is about  5×10⁻³ meter and sand grain is about 1×10⁻³ meter.

We can say,

5×10⁻³ > 1×10⁻³

The human skin's thickness is 5 times greater than the thickness of a sand grain.

Hence, we have to multiply by 5 to measure of the thickness of a sand grain to make it equal to human skin's measurement,

Hence, It will take 5 grains of sand to match the thickness of a human's skin.

Answer:

(x² - 9)(x² - 1)

Step-by-step explanation:

Using Quadratic trinomials

Factor x⁴ - 10x² + 9

Step 1: Find the two integers whose product of 9 and whose sum of -10

Product

-9 × -1 = 9

Sum

-9 + -1 = -10

Step 2: Use -1 and -9 to complete the factors

x⁴ - 10x² + 9 = (x² - 9)(x² - 1)

Step 3: Use the foil method to check the factors

(x² - 9)(x² - 1) = x⁴ - 1x² - 9x² + 9 = x⁴ - 10x² + 9
