What is the solution to y = 0.7x for the replacement set x = {2}?.

Answers

The question ask to solve and compute the said problem if x = 2 and the equation is y=0.7x. In that alone, the value of y is 1.4 so it means its solution, by means of representing it coordinate, it should be (2,1.4). I hope you are satisfied with my answer and feel free to ask for more

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.a) after how many years will she have 64 rabbits?

It is geometric sequence.
Therefore:

After 4 yours she will have over 64 rabbits.

A pair of equations is shown below.3x − y = 9
y = −2x + 11

If the two equations are graphed, at what point do the lines representing the two equations intersect?
(4, 3)
(3, 4)
(9, 11)
(11, 9)

Answers

Answer:

Hence, the two equations intersect at:

(4,3)

Step-by-step explanation:

We are given:

A pair of equations:

3x − y = 9

y = −2x + 11

now, on graphing these equations.

as we can clearly see from the graph the two lines intersect at (4,3)

Hence, the two equations intersect at:

(4,3)

3x − y = 9
y = −2x + 11

3x − (−2x + 11) = 9
3x + 2x - 11 = 9
5x = 9 + 11
5x = 20
x = 4

y = −2x + 11 = -2*4+11 = 3

(4, 3)

The figure is made up of a square and a rectangle. Find the area of the shaded region.

Answers

Answer:

40 square metres

Step-by-step explanation:

The shaded region is of a triangle, whose area is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Since the left figure is a square with side lengths 10, we know that the height of the triangle is also 10 metres. The right figure is a rectangle with length 4. Since the total base length of the entire figure is 18 and the base of the square is 10, then the width of the rectangle is 18 - 10 = 8 metres.

This width is also the base of the triangle, so b = 8.

Now plug these values into the equation:

A = (1/2) * b * h

A = (1/2) * 8 * 10 = (1/2) * 80 = 40

The area is 40 square metres.

Answer:

40 m²

Step-by-step explanation:

Area of any triangle:

½ × base × height

base = 18 - 10 = 8

height = 10

Area:

½ × 8 × 10

40 m²

Which best describes the range of the function f(x) = 2/3(6)x after it has been reflected over the x-axis?A. all real numbers
B. all real numbers less than 0
C. all real numbers greater than 0
D. all real numbers less than or equal to 0

Answers

The right answer for the question that is being asked and shown above is that: "D. all real numbers less than or equal to 0." This is the statement that best describes the range of the function f(x) = 2/3(6)x after it has been reflected over the x-axis

The correct answer is:

D) all real numbers less than or equal to 0.

Explanation:

When you reflect a function across the x-axis, you negate every y-coordinate in the function.

In our original function, our y-values will all be positive. Reflecting this across the x-axis will make all of the y-values negative; this means the range, or set of y-values, will be less than or equal to 0.
