Find the slope of the line.
Help pleasee!!

When completing the square is carried out on the quadratic [tex]x^2+11x[/tex] we get

[tex]x^2+11x+\dfrac{121}{4}[/tex]

when expressed as a binomial squared, we get

[tex]\left(x+\dfrac{11}{2}\right)^2[/tex]

To complete the square, we need to add a term to the expression

[tex]x^2+11x[/tex]

that would make it a perfect square. Generally, given the quadratic expression

[tex]x^2+bx[/tex]

to make it a perfect square, we have to add half the square of the coefficient of [tex]x[/tex]. That is, add [tex]\left(\frac{b}{2}\right)^2[/tex], or [tex]\frac{b^2}{4}[/tex] to the quadratic expression to get

[tex]x^2+bx+\dfrac{b^2}{4}[/tex]

which, when factored into a binomial squared becomes

[tex]\left(x+\dfrac{b}{2}\right)^2[/tex]

In our case, the quadratic [tex]x^2+11x[/tex] will become

[tex]x^2+11x+\dfrac{121}{4}[/tex]

and when expressed as a binomial squared, we get

[tex]\left(x+\dfrac{11}{2}\right)^2[/tex]

Answer:

I'm pretty sure it's B.

Answer:

B. y=-4/3x+4

Step-by-step explanation:

Find the y-intercept you will always find it on the y axis (in this case it is 4)

the slope is -4/3 because you go down 4 times (Going down is negative up is positive) and right 3 times (Right is positive and left is negative)

Slope= rise/run

Answer:

Fraction of saving = 1/8

Step-by-step explanation:

Given:

Spent on bills = 3/8

Spend on food = 2/5

Spend on entertainment = 1/10

Find:

Fraction of saving

Computation:

Fraction of saving = 1 - Spent on bills - Spend on food - Spend on entertainment

Fraction of saving = 1 - 3/8 - 2/5 - 1/10

By taking LCM

Fraction of saving = [40 - 15 - 16 - 4]/40

Fraction of saving = [5]/40

Fraction of saving = 1/8

Step-by-step explanation:

−9(m+3)+14=−49

Step 1: Simplify both sides of the equation.

−9(m+3)+14=−49

(−9)(m)+(−9)(3)+14=−49(Distribute)

−9m+−27+14=−49

(−9m)+(−27+14)=−49(Combine Like Terms)

−9m+−13=−49

−9m−13=−49

Step 2: Add 13 to both sides.

−9m−13+13=−49+13

−9m=−36

Step 3: Divide both sides by -9.

Answer:

[tex]\frac{21}{100}[/tex]

Step-by-step explanation:

As you can see in the table, there are 21 people that have dogs but don't take walks. To find the probability, divide 21 by the total amount of people that attended the survey:

[tex]\frac{21}{100}[/tex]

This fraction can't be simplified.

The probability, represented as a fraction in simplest form, that a randomly selected person does not take walks but has a dog is [tex]\frac{21}{100}[/tex].

Answer:

Perimeter of rectangle is 23.34

Step-by-step explanation:

The coordinates of the vertices of a rectangle are (-4, 3), (-1, 5),(3, – 1), and (0, – 3).

What is the perimeter of the rectangle?

The formula to find perimeter of rectangle is: [tex]Perimeter=2(l+w)[/tex]

We need to find length and width first using the coordinates (-4, 3), (-1, 5),(3, – 1), and (0, – 3).

Let A=(-4, 3) B=(-1, 5) C=(3, – 1) and D=(0, – 3) according to the figure attached.

So, If we find distance of point AB it can be considered length of rectangle and distance of point AC can be considered width of rectangle

The formula used to find distance is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Finding distance AB, we have [tex]x_1=-4, y_1=3, x_2=-1, y_2=5[/tex]

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-1-(-4))^2+(5-3)^2}\\Distance=\sqrt{(-1+4)^2+(5-3)^2}\\Distance=\sqrt{(3)^2+(2)^2}\\Distance=\sqrt{9+4}\\Distance=\sqrt{13}\\Distance=3.61[/tex]

So distance between point A and B is 3.61

Finding distance AC, we have [tex]x_1=-4, y_1=3, x_2=3, y_2=-1[/tex]

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(3-(-4))^2+(-1-3)^2}\\Distance=\sqrt{(3+4)^2+(-1-3)^2} \\Distance=\sqrt{(7)^2+(-4)^2} \\Distance=\sqrt{49+16} \\Distance=\sqrt{65}\\Distance=8.06[/tex]

So, distance between point A and C is 8.06

We have length = 3.61 and width = 8.06

Using formula of perimeter

[tex]Perimeter=2(l+w)\\Perimeter=2(3.61+8.06)\\Perimeter=2(11.67)\\Perimeter=23.34[/tex]

So, Perimeter of rectangle is 23.34

Answer:

13 1/3

Step-by-step explanation:

So the question is Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.

First divide 60 by 9 to figure out the first part of the ratio. So that is 60/9 or    6 2/3.

Then multiply 2 by 6 2/3 which is 13 1/3.

Finally when rounded to the nearest foot, it will be 13.

Answer:

we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.

Step-by-step explanation:

As Misty determined the equation of linear function:

[tex]y=-2x+9[/tex]

We need to check whether she has got the correct equation or not.

As the linear equation passes through the points  [tex](1, 7)[/tex] and [tex](2, 5)[/tex].

Finding the slope:

The slope between two points  [tex](1, 7)[/tex] and [tex](2, 5)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:7\right),\:\left(x_2,\:y_2\right)=\left(2,\:5\right)[/tex]

[tex]m=\frac{5-7}{2-1}[/tex]

[tex]m=-2[/tex]

As we know the point-slope form is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

So, the equation of the line will be:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=-2\left(x-2\right)[/tex]

Add 5 to both sides

[tex]y-5+5=-2\left(x-2\right)+5[/tex]

[tex]y=-2x+9[/tex]

From the above calculation, we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
