Answer:

1/6

Step-by-step explanation:

Answer:

5/6x = -10

=> 5/6x = -10/1

by cross multiplication

=> 6x × - 10 = 5 × 1

=> 6x = 5 × 1 / -10

=> 6x = 1/-2

=> x = 1/-2 ×6

=> x = 1/-12

Hope this helps..

The solution of the equation is,

⇒ x = - 2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ 3 (4x + 6) = 9x + 12

Now,

Solve the equation as;

⇒ 3 (4x + 6) = 9x + 12

⇒ 12x + 18 = 9x + 12

⇒ 12x - 9x = 12 - 18

⇒ 3x = - 6

⇒ x = - 6/3

⇒ x = - 2

Answer:

B and D

Step-by-step explanation:

The statement  (A) Centres: Career A has greater median hourly earnings than career (B) and statement (B) Spreads: The hourly earnings for career B are more spread out are correct.

A dot plot, also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.

We have given dot plot in the picture.

As we can see from the dot plot:

Median for career A = 35

Median for career B = 25

And career B dot plot is more spread.

Thus, the statement  (A) Centres: Career A has greater median hourly earnings than career (B) and statement (B) Spreads: The hourly earnings for career B are more spread out are correct.

Answer:

1,-12

Step-by-step explanation:

The coordinates of D' after translation is (1, -12).

Option B is the correct answer.

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

Parallelogram coordinates:

A = (-3, 4)

B = (3, 4)

C = (1, -2)

D = (-5, -2)

Now,

Translation of (x, y) → (x + 6, y - 10) is applied.

This means,

Parallelogram coordinates:

A' = (-3, 4) → (-3 + 6, 4 - 10) = (3, -6)

B' = (3, 4) → (3 + 6, 4 - 10) = (9, -4)

C' = (1, -2) → (1 + 6, -2 - 10) = (7, -12)

D' = (-5, -2) → (-5 + 6, -2 - 10) = (1, -12)

Thus,

The coordinates of D' is (1, -12).

The transformation for the given function is vertical compression or stretch.

The given functions are y=3x² and y=x².

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The graph for the given functions can be determined as follows

To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Horizontal Shift: None

Vertical Shift: None

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Compressed

Therefore, the transformation for the given function is vertical compression or stretch.

Answer:

The explicit formula of the sequence is [tex]a_n=5(\frac{1}{5})^{n-1}[/tex] for [tex]n \geq 2[/tex]

Step-by-step explanation:

Sixth term in a geometric sequence =[tex]\frac{1}{625}[/tex]

Common ratio =[tex]\frac{1}{5}[/tex]

Formula of nth term =[tex]a_n=ar^{n-1}[/tex]

Substitute the values

So,[tex]\frac{1}{625}=a(\frac{1}{5})^{6-1}\\\frac{1}{625}=a(\frac{1}{5})^{5}\\\frac{1}{625} \times 5^5=a[/tex]

5=a

Substitute the value in 1

So,[tex]a_n=5(\frac{1}{5})^{n-1}[/tex]

So, Option C is true

Hence the explicit formula of the sequence is [tex]a_n=5(\frac{1}{5})^{n-1}[/tex] for [tex]n \geq 2[/tex]

Answer: m>50

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The amount charged by company A (120) must be less (<) than the fixed amount charged by company B (75), plus the product of the cost per mile driven (0.90) and the number of miles driven (m).

120 < 75+ 0.90m

Solving for m:

120-75<0.90m

45<0.90m

45/0.90 <m

50<m

Company A charges less than Company B when m > 50.

Feel free to ask for more if needed or if you did not understand something.

Answer:

Step-by-step explanation:

Well, first of all the shape needs to be a rectangle not a square. And i think you do not understand how coordinates work.

The coordinate (-1, 4). The first number -1 is the number on the x-axis, 4 is the number on the y-axis. Same thing with the other coordinate.

After you put down the two dots, you know that the Perimeter is 24 cm.

P = 2(a + b) = 24 => a+b = 12 => a = 4 => b = 8

The sides are 4 and 8 units long.

Step-by-step explanation:

Answer:

y = - x +9

Step-by-step explanation:

slope = (9-0)/(0-9) = - 1

line equation : y= mx + c

find c : 9= - 1*0 +c ....... >> c = 9

y = - x +9 ans

Answer:

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-0)/((0-9))

m=9/(0-9)

m=9/-9

m=-1

y=mx+c

y=-1*x+c

y=-x+c

plug in (9,0) into the equation

0=-1*9+c

0=-9+c

-c=-9

c=9

y=-x+9

you wrote it correctly too, but I think the problem is that it only takes -x not -1x
