Answer:

The linear equation for the line which passes through the points given as (1,5) and (4,11), is written in the point-slope form as y=2x+3.

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (1,5) and (4,11).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 2

Determine the slope of the line.

The points through which the line passes are given as (1,5) and (4,11). Next, the formula for the slope is given as,

[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

Substitute 11&5 for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and [tex]$4 \& 1$[/tex] for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,

[tex]$$\begin{aligned}m &=\frac{11-5}{4-1} \\m &=\frac{6}{3} \\m &=2\end{aligned}$$[/tex]

Step 2 of 2

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

[tex]$$y-y_{1}=m\left(x-x_{1}\right)$$[/tex]

Substitute 2 for [tex]$m, 1$[/tex] for [tex]$x_{1}$[/tex], and 5 for [tex]$y_{1}$[/tex] in the above equation and simplify using the distributive property as follows,

[tex]$$\begin{aligned}&y-5=2(x-1) \\&y-5=2 x-2 \\&y=2 x-2+5 \\&y=2 x+3\end{aligned}$$[/tex]

This is the required linear equation.

If the distance is 45 miles and speed of both cyclist is 14 and 16 miles per hour then they will take time of 1.5 hour to meet.

Given First cyclist is riding at 14 miles per hour and second at 16 miles per hour. The distance is 45 miles.

We know that speed is the distance covered by an object in a particular period of time.

Speed=distance/time.

It is expressed as kilometers per hour or miles per hour, etc.

If both riders are riding towards each other then the speed will be 16+14 =30 miles per hour.

Distance=45 miles.

Time =distance/speed

=45/30

Answer:

w = 12

l = 18

Step-by-step explanation:

Hello!

Recall the perimeter of a rectangle is twice the sum of the length and the width of the rectangle.

Let w be the width. The length is 6 less than twice the width. That means, l is 2w - 6.

Plug it into the formula and solve, given that P is 60.

The width is 12 inches. We can plug in 12 for 2w - 6 to find the length.

The length is 18 inches.

The width is 12 inches, and the length is 18 inches.

The equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y. (Correct choice: D)

In accordance with the statement, we find that the parabola has its vertex at the origin, therefore it is horizontal and its vertex constant (C) is negative as its focus is in the negative part of the x-axis. Therefore, the equation of the parabola in standard form has the following form:

x² = C · y, for C < 0.     (1)

In consequence, the equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y.

The number is 5 if two increased by a number is a dozen. In other words, the correct answer is 5 by solving equations.

Step 1: Write the given information as an equation. "Two increased by a number" can be represented as 2 + x, where x is the unknown number.

Step 2: Translate "Two increased by a number is a dozen" into an equation. The word "a dozen" refers to the number 12.

[tex]2 + x = 12.[/tex]

Step 3: Solve the equation for x. To isolate x, subtract 2 from both sides of the equation:

[tex]2 + x - 2 = 12 - 2.[/tex]

This simplifies to x = 10.

Step 4: Verify the solution. Substitute the value of x back into the original equation:

2 + 10 = 12.

This equation is true, so x = 10 is indeed the solution.

Therefore, the number is 10.

The recursive function of a ball with a 67% rebound is a(n) = 0.67a(n-1)

The rebound is given as:

r = 67%

Express as decimal

r = 0.67

So, the recursive function is:

a(n) = Previous height * r

This gives

a(n) = a(n-1) * 0.67

Evaluate

a(n) = 0.67a(n-1)

Hence, the recursive function is a(n) = 0.67a(n-1)

Basketball

The initial height is given as:

a(1) = 54

So, we have:

a(2) = 0.67 * 54 = 36.18

a(3) = 0.67 * 36.18 = 24.24

Tennis ball

The initial height is given as:

a(1) = 58

So, we have:

a(2) = 0.67 * 58 = 38.86

a(3) = 0.67 * 38.86 = 26.04

Table-tennis ball

The initial height is given as:

a(1) = 26

So, we have:

a(2) = 0.67 * 26 = 17.42

a(3) = 0.67 * 17.42 = 11.67

Hence, the complete table is:

Your question presented was: [tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )-\frac{1}{3} (\frac{1}{2} -\frac{2}{3}x)[/tex]

Okay, lets distribute this problem and break it into two parts. We will distribute 2/5 and -1/3 to the numbers in parenthesis. This is the distributive property.

Step 1.
[tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )[/tex] when distributed is [tex]\frac{2}{15} x - \frac{30}{40}[/tex]

Please note that -1/3 can be rewritten as + -1/3. So you must distribute the negative.

Step 2.
[tex]\frac{-1}{5} + \frac{2}{9} x[/tex]
So..lets put the 2 parts of the equation together

[tex]\frac{2}{15} x - \frac{30}{40}[/tex] + [tex]\frac{-1}{5} + \frac{2}{9} x[/tex] can be simplified by getting the common denominator.

You can only add like terms, so those fractions with x can only be combined with x.
Step 3.
Lets reformat while we're at it
[tex]\frac{6}{45} x + \frac{10}{45} x -\frac{30}{40} -\frac{8}{40}[/tex]

We got 45 because the LCM (Lowest Common Multiple) of 15 and 9 was 45. We multiplied both sides of the fraction by 3 for 2/15x and we multiplied by 5 on both parts of the fraction for 2/9x.

Now we combine.
Step 4.
[tex]\frac{16}{45}x-\frac{38}{40}[/tex]. We can still simplify!
Step 5.
-38/40 can be simplified by a common factor, 2! So our final answer is
[tex]\frac{16}{45}x-\frac{19}{20}[/tex]

The coordinates of the circumcenter of triangle having coordinates of (0,0),(4,0),(4,-3) are (1,-17/6).

Given The coordinates of triangle are (0,0),(4,0),(4,-3).

Let the triangle be ABC.

Let the coordinates of the circumcenter be D(x, y).

We know that the length of circumcenter from the corner points are equal to each other.

In this way AD=BD=DC

AD=[tex]\sqrt{(x-0)^{2} +(y-0)^{2} }[/tex]

=[tex]\sqrt{x^{2} +y^{2} }[/tex]

DC=[tex]\sqrt{(4-x)^{2} +(-3-y)^{2} }[/tex]

AD=DC

[tex]\sqrt{x^{2} +y^{2} }[/tex]==[tex]\sqrt{(4-x)^{2} +(-3-y)^{2} }[/tex]

Squaring both sides we get

[tex]x^{2} +y^{2}=16+x^{2} -8x+9+3y+3y+y^{2}[/tex]

8x-6y=25--------------------1

DC=BD

[tex]\bf{x > -4 \ \ \to \ \ \ Answer}[/tex]

Answer:

{x | x > -4}

Step-by-step explanation:

{a few basic reminders:  > means greater than; < means less than; ≥ means greater than or equal to; ≤ means less than or equal to

for example: 4 < 7

                     4 ≤ 4

                     4 ≥ 3

                     4 > 3}

When we see an inequality, such as 9x > -36, we are trying to figure out what possible numbers x can be to make this statement true.

We can either use logic / words (see below), or in a much more efficient manner, we can solve this algebraically [as though it were an equation]

So, like when working with any other variable, we want to isolate x:
9x > -36

÷9    ÷9

   x > -4  

just in case none of this makes sense (it can be quite confusing at first),

here's how we can think about it logically

we know that whatever multiplies with 9 must be more than -36, and because -4 multiples with 9 to be exactly -36, any number greater than -4 also will be greater than -36

meaning that x must be more than -4, which we express as: x > -4

So, the solution set (solution set means set of possible solutions) is

{x | x > -4}

The transformed function is:

[tex]g(x) = ( (x + 1)/3 - 2)^2 + 2*( (x + 1)/3 - 2)[/tex]

The parent function is:

[tex]f(x) = x^2 + 2x[/tex]

Here the axis of symmetry is at:

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

So first we need to apply a horizontal compression by a factor of 3 with respect to the line x = -1.

Here we can, for the moment, define a new variable that is zero when x = -1, let's define:

z = x + 1.

x = z - 1

Writing our function in terms of z, we get:

[tex]f(z) = (z - 1)^2 + 2*(z - 1)[/tex]

Now we can apply a compression by a factor of 3 around the origin. Then we have:

[tex]f(z/3) = (z/3 - 1)^2 + 2*(z/3 - 1)[/tex]

Returning to the original variable, we have:

[tex]f((x+1)/3) = ( (x + 1)/3 - 1)^2 + 2*( (x + 1)/3 - 1)[/tex]

Now we want to shift it one unit to the right, then we have:

g(x) = f( (x + 1)/3 - 1)

Replacing the actual function we get:

[tex]g(x) = f((x+1)/3 - 1) = ( (x + 1)/3 - 1 - 1)^2 + 2*( (x + 1)/3 - 1 - 1)\\\\g(x) = ( (x + 1)/3 - 2)^2 + 2*( (x + 1)/3 - 2)[/tex]

Answer:

[tex]\left[ \dfrac{4}{3},4 \right][/tex]

Step-by-step explanation:

Inequality 1

[tex]3y-13\geq -9[/tex]

Add 13 to both sides:

[tex]\implies 3y-13+13\geq -9+13[/tex]

[tex]\implies 3y\geq 4[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3y}{3}\geq \dfrac{4}{3}[/tex]

[tex]\implies y \geq \dfrac{4}{3}[/tex]

Therefore, y is equal to or bigger than 4/3.

Inequality 2

[tex]3y-13\leq -1[/tex]

Add 13 to both sides:

[tex]\implies 3y-13+13\leq -1+13[/tex]

[tex]\implies 3y\leq 12[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3y}{3}\leq \dfrac{12}{3}[/tex]

[tex]\implies y\leq 4[/tex]

Therefore, y is equal to or smaller than 4.
