Answer:

  x = -9

Step-by-step explanation:

The value 13-8x apparently is the measure of the arc in degrees. That is the same as the measure of the central angle, shown as 85°. Then we have ...

  85 = 13 -8x

  72 = -8x . . . . . . subtract 13

  x = -9 . . . . . . . . divide by -8

The value of x is -9.

C. y-2 = 3(x-4)
D. Y + 2 = 3(x-4)
Please answer asap

Answers

Answer:

B

Step-by-step explanation:

point-slope formula: y-y1 = m(x-x1)

y1 = 4 ; x1 = -2 ; m (slope) = 3

plugging it in to the formula, you get y-4 = 3(x-(-2)

then you get y-4 = 3(x+2)

The question is incomplete. The complete question is :

A survey was done to determine the relationship between gender and subject preference. A total of  56 students were surveyed to determine if they liked math, English, social studies, or science as their  favorite subject. The results were then broken down based on whether the respondent was male or  female.

Which of the following is the closest to the joint relative frequency of being a male who likes social studies ?

Solution :

A two way table used in statistics and mathematics is used to show the frequencies or the relative frequencies for any two categorical variables.  One of the category is represented by the rows while the other categories by a column.

Here, in this table it is given that the total surveyed = 56 students

From the table, we know that number of males who likes social studies = 8

Therefore, the closest to the joint relative frequency for being a male who likes the subject social studies is given by :

[tex]$=\frac{8}{56}$[/tex]

[tex]$=\frac{1}{7}$[/tex]

What is the common solution for the equations y = 3x + 1 and y = x + 3? Write your answer an ordered pair!

Answers

Answer:

(1,4)

Step-by-step explanation:

Hi there!

We're given the system:

y=3x+1

y=x+3

We need to find the common solution (the point at which the lines intersect); we do this by finding the value of the variables.

Let's start with x

Since both equations equal y, we can make 3x+1 and x+3 equal to each other, because of a property known as transitivity (if a=b and b=c, then a=c)

3x+1=x+3

subtract 1 from both sides

3x=x+2

subtract x from both sides

2x=2

divide both sides by 2

x=1

we found the value of x

now we need to find the value of y

We do this by plugging x as 1 into either one of the equations to solve for y

let's use y=x+3 for example

substitute x as 1

y=1+3

add

y=4

we found the value of y.

Your question asks for the answer to be written as an ordered pair, which will be (1,4)

Hope this helps!

Answer:

(1, 4 )

Step-by-step explanation:

Given the 2 equations

y = 3x + 1 → (1)

y = x + 3 → (2)

Substitute y = 3x + 1 into (2)

3x + 1 = x + 3 ( subtract x from both sides )

2x + 1 = 3 ( subtract 1 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 1 + 3 = 4

solution is (1, 4 )

Answers

Answer:

To create function h, function f was translated 2 units right , translated 4 units up and reflected across the x axis

Step-by-step explanation:

Given

[tex]f(x) = x^3[/tex]

[tex]h(x) =-(x + 2)^3 - 4[/tex]

Required

Complete chart

First: f(x) was translated right by 2 units

The rule of right translation is [tex](x,y) \to (x + 2,y)[/tex]

So, we have:

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

[tex]f'(x) = (x + 2)^3[/tex]

Next: f'(x) was translated up by 4 units

The rule of down translation is [tex](x,y) \to (x,y+4)[/tex]

So, we have:

[tex]f"(x) = f'(x) +4[/tex]

[tex]f"(x) = (x + 2)^3 +4[/tex]

Lastly, f"(x) was reflected across the x-axis;

The rule of this reflection is: [tex](x,y) \to (x,-y)[/tex]

So, we have:

[tex]h(x) = -f"(x)[/tex]

[tex]h(x) = -[(x+2)^3 + 4][/tex]

[tex]h(x) = -(x+2)^3 - 4[/tex]

Answers

Answer:

Resultados debajo

Step-by-step explanation:

Dada la siguiente información:

Tasa de interes anual (i)= 4,8%

Inversión inicial (VP)= $1.000.000

Para calcular el valor final (VF), debemos usar la siguiente formula:

VF= VP*(1 + i)^n

Para 5 años:

VF= 1.000.000*(1,048^5)

VF= $1.264.172,72

Para 18 años:

VF= 1.000.000*(1,048^18)

VF= $2.325.429,02

LENGHT OF THE RECTANGLE IS 7 LESS THAN THE TWICE OF THE BREADTH THEN FIND ITS DIMENSIONS IF THE PERIMETER IS 40 CM

Answers

Step-by-step explanation:

Length of rectangle = 7 less than the twice the breadthPerimeter = 40 cm

Let us say the breadth as b and length as l.

→ Length = 7 less than the twice the breadth

l = 2b - 7 ...(1)

Now, according to the question,

Perimeter of rectangle = 2(l + b)

→ 40 = 2(2b - 7 + b)

→ 40 = 2(3b - 7)

→ 40 = 6b - 14

→ 40 + 14 = 6b

→ 54 = 6b

→ 54 ÷ 6 = b

9 m = Breadth

Now, finding length.

→ l = 2b - 7

→ l = 2(9) - 7 m

→ l = 18 - 7 m

Length = 11 m

The circle below has center H. suppose mIJ=84. What is mIGL

Answers

Answer:

m∠IGJ = 42°

Step-by-step explanation:

It's given in the question,

m(arc IJ) = 84°

And we have to get the measure of ∠IGJ.

By using the property of inscribed angle and the intercepted arc.

"Measure of an inscribed angle is half of the measure of intercepted arc"

m(arc IJ) = 2(m∠IGJ)

84° = 2(m∠IGJ)

m∠IGJ = 42°
