What is the slope of this ?

Answer:

Rhombus I guess

Step-by-step explanation:

Because rhombus have equal interior angles which is 90° so we can bisect or divide equally

Answer:

Step-by-step explanation:

Given formula:

Solving for n:

[tex]S = 180(n - 2) \\ S = 180n - 360 \\ 180n =( S + 360) \\ n = \frac{(S+ 360)}{180} [/tex]

where, n =number of sides of polygon

S =sum of the degree measures of the interior angles of the polygon

Answer:

Option C

Step-by-step explanation:

Given expression is [tex]y^{-\frac{4}{3}}[/tex].

Exponent of this expression is [tex](-\frac{4}{3})[/tex].

Option (A)

[tex]-\frac{4}{3}y[/tex]

Since, exponents and coefficients of both the expressions are different.

They are not equivalent.

Option (B)

[tex]-(\sqrt[3]{y})^4=-(y^{\frac{1}{3}})^4[/tex]

            [tex]=-y^{\frac{4}{3}}[/tex]

Here, exponent is with positive notation [tex](+\frac{4}{3})[/tex] while in the original expression it is negative [tex](-\frac{4}{3})[/tex].

Therefore, both the expressions are not equivalent.

Option (C)

[tex]\frac{1}{(\sqrt[3]{y})^4}=(\sqrt[3]{y})^{-4}[/tex]

         [tex]=y^{-\frac{4}{3}}[/tex]

Both the expressions are equivalent.

Option (D)

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

Exponents of both the expressions are different.

Therefore, not equivalent.

Option (E)

[tex]\frac{1}{(\sqrt[4]{x})^3}=(\sqrt[4]{x})^{-3}[/tex]

         [tex]=y^{-\frac{3}{4}}[/tex]

Exponent of this expression is different from the original expression.

Therefore, not equivalent.

Option (C) will be the correct option.

Step-by-step explanation:

Pr ( A & B ) , ie Probability (Senior Student with Statistics) = 0.15

Given : Event A = Student is senior, Event B = Student takes statistics

Answer: x=68

Step-by-step explanation:

A. It’s asking what the last test must have to be (x) for all five tests to average out to an 80. This can be represent by:

(95+76+77+84+x)/5=80

The first four numbers are the existing test scores and x is the score you need. This is all divided by five so that you can find the average of all of these added together, which will equal 80, because that’s the grade you’re trying to get. Next, just solve for x:

= 95+76+77+84+x=80(5)

= 332+x=400

X=68

B. I got 74 for this one by using the same process as in part a, but I divided the left side by six and multiplied x by two: (95+76+77+84+2x)/6=80

But I’m not completely positive about this answer. A is definitely right though

B. 16p+6

Step-by-step explanation:

Answer:

B . 16p + 6

Step-by-step explanation:

12p + 9 + 4p -3

collect like terms

(12p + 4p) + (9 - 3)

16p + 6

Answer:

4x+2

Step-by-step explanation:

Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .

12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.

4x+2 = length. Hope this helps!

Answer:

No parallel lines

Lines 1 and 3 are perpendicular

Step-by-step explanation:

Given:

[tex]Line\ 1:y = -\frac{3}{4}x + 3[/tex]

[tex]Line\ 2: \frac{2}{8}x -6y = 2[/tex]

[tex]Line\ 3: 3y = 4x + 7[/tex]

Required

Determine if they are parallel, perpendicular or not

The slope intercept of a line has the form:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

First, we calculate the slope of each lines

[tex]Line\ 1:y = -\frac{3}{4}x + 3[/tex]

Compare the above to [tex]y = mx + b[/tex]

[tex]m_1 = -\frac{3}{4}[/tex]

[tex]Line\ 2: \frac{2}{8}x -6y = 2[/tex]

[tex]\frac{2}{8}x -6y = 2[/tex]

Make -6y the subject

[tex]-6y = 2 - \frac{2}{8}x[/tex]

Divide through by -6

[tex]y = -\frac{2}{6} + \frac{2}{8*6}x[/tex]

[tex]y = -\frac{1}{3} + \frac{1}{8*3}x[/tex]

[tex]y = -\frac{1}{3} + \frac{1}{24}x[/tex]

[tex]y = \frac{1}{24}x-\frac{1}{3}[/tex]

Compare the above to [tex]y = mx + b[/tex]

[tex]m_2 = \frac{1}{24}[/tex]

[tex]Line\ 3: 3y = 4x + 7[/tex]

[tex]3y = 4x + 7[/tex]

Divide through by 3

[tex]y = \frac{4}{3}x + \frac{7}{3}[/tex]

Compare the above to [tex]y = mx + b[/tex]

[tex]m_3 = \frac{4}{3}[/tex]

So, we have:

[tex]m_1 = -\frac{3}{4}[/tex]

[tex]m_2 = \frac{1}{24}[/tex]

[tex]m_3 = \frac{4}{3}[/tex]

None of the slopes are the same, so none of the lines are parallel.

However, lines 1 and 3 are perpendicular.

This is shown below

When the slope of two lines satisfy the following condition, then they are  perpendicular.

[tex]m_1 = -\frac{1}{m_3}[/tex]

This gives:

[tex]-\frac{3}{4} = -\frac{1}{4/3}[/tex]

[tex]-\frac{3}{4} = -1/\frac{4}{3}[/tex]

Convert / to *

[tex]-\frac{3}{4} = -1*\frac{3}{4}[/tex]

[tex]-\frac{3}{4} = -\frac{3}{4}[/tex]

Answer:

4y = -x + 31

Step-by-step explanation:

Given that one equation in a system of equations is y = 4x - 5 write a second equation to complete the system if the solution to the system is (3,7)

Since the solution of the system is (3, 7), that means the two lines of equations meet or intersect at point X = 3 and Y = 7

Let assume that the two equations are perpendicular to each other. Then, there slope can be expressed as

M1M2 = -1

Where M1 = 4

Find M2

4M2 = -1

M2 = -1 / 4

Using general linear equation

Y = MX + C

Let's find C by substituting Y, X and M2

7 = -1 /4( 3 ) + C

7 = -3/4 + C

C = 7 + 3/4

C = 31/4

Substitute C back into the equation

Y = -1/4X + 31/4

4y = -x + 31

Therefore, the second equation is

4y = -x + 31
