He will read 700 pages each day.He must be committed to reading this amount of pages each day in order to finish the book in two days.

1. There are 1400 pages in the book.

2. The book must be read in even days.

3. To find the number of pages read each day, divide 1400 by 2 (since it must be read in two days).

4. The answer is 700 pages read each day.

The book contains 1400 pages and must be read in two days. To find the answer, the number of pages must be divided by two. This means that each day, he must read 700 pages. This is the same amount each day, so he will read the same amount of pages for each day he reads it. He will have to read for two days in order to finish the book and will read 700 pages for each day. He must be committed to reading this amount of pages each day in order to finish the book in two days.

Answer:

f(-4) = -20

f(1) = 5

f(2) = 10

f(3) = 15

f(6) = 30

Step-by-step explanation:

Since the equation is f(x) = 5x, you will have to substitute the x-values into the equation to find out what f(x) equals for each one.
For example, for x = -4, f(-4) would equal -20 since 5 * -4 = -20.
The rest would be:
f(1) = 5 * 1 = 5

f(2) = 5 * 2 = 10

f(3) = 5 * 3 = 15

f(6) = 5 * 6 = 30

Therefore , the solution to the given problem of equation comes out to be $12 for a geranium and $11 for a square foot of grass.

When connecting two statements, a mathematical equation uses its equal sign (=) to denote equivalence. An equation in algebra is a claim that establishes the comparability of two equations. For instance, the formula 5x + 5 = 14 establishes a link between the two integers. The spaces seen between phrases with either front of a letter are used to form a mathematical connection. The lone variable so the only outcome are frequently the symbol. For instance, 8x - 4 = 2.

Here,

To start, you should underline and group pertinent information. Sort the products according to the individual who purchased them. We can give each of the two purchased things a constant or letter as there are only two of them:

Kim

5 feet by 2 feet (X for short) of grass

10 geraniums, designated as "Y" geraniums; total cost: $175

Matt

9 ft 2 of grass (let's call it grass X).

Four geraniums, designated as Y.

$147 in total

Now that the data has been split, you may create two equations: one for Matt and one for Kim.

Kim

5x + 10y = $175

Matt 9x plus 4y = $147

Observe how the numbers remained constant, but I eliminated the units and substituted X or Y depends on just what we assigned. We can start solving now.

I'll take the x out of Kim's equation. the following steps:

1) 5x + 10y = $175 Rewriting the equation

2) If you'd want to perform y first, 5x = $175 - 10y (again, you can still do y first as we're trying to isolate x). That's exactly how I did it.)

3) (5x)÷5 = ($175 - 10y)÷5 (divide both aspects of the equation by 5) 

4) 5x + 10y = $175

=>5x + 10($12) = $175 

5x + 10($12) = $175  

Add the value of y = $12 to Kim's equation to get 5x + $120 = $175.

5) 5x = $175 - $120

=> 5x = $55

=>  x = $11

x = $11

Therefore , the solution to the given problem of equation comes out to be $12 for a geranium and $11 for a square foot of grass.

The requried dimension of the original rectangle is given as length = 25 cm, width = 10 cm.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Let the length and width of the original rectangle be x and y,
According to the quesiton,

The perimeter of a rectangle is 70 cm.
2 [x + y] = 70
x  + y = 35 - - - -(1)

Now,
its length is decreased by 5 cm and its width is increased by 5 cm, its area will increase by 50 cm².
Area of the new rectangle = area of the original rectangle + 50
(x  - 5)(y + 5) = xy + 50

from equation 1,

(x - 5)(35 - x + 5) = x(35 - x) + 50
-x² - 200 + 40x + 5x = 35x - x² + 50
45x - 35x = 50 + 200
10x = 250
x = 25

Now,
y = 35 - 25
y = 10

Thus, the requried dimension of the original rectangle is given as length = 25 cm, width = 10 cm.

Finding the mirror image of a curve with respect to a line is a relatively straightforward task.

Mirror image is an exact reflection of an object or an image as seen in a mirror. It is an image that is flipped from left to right, with the left side of the image becoming the right side and vice versa. This type of reflection is also known as a lateral inversion. In art and photography, mirror images are often used for aesthetic purposes and to create symmetry.

Firstly, you need to determine the line of reflection. This can be identified by using the angle bisector of the two lines that form the curve. Once you have identified the line of reflection, draw a line perpendicular to it. This is the axis of symmetry.

Next, draw a line parallel to the axis of symmetry. This line will serve as the mirror line. Now, you can start plotting the points of the curve with respect to the mirror line. To do this, take the midpoint of the curve and reflect it across the mirror line. Then, take the points on either side of the midpoint, and reflect them across the mirror line as well. Repeat this process for all the points on the curve.

Finally, connect the reflected points to form the mirror image of the curve. This will give you the same curve, just flipped across the mirror line. It is important to note that the mirror image of the curve will be a mirror reflection of its original shape, but its orientation may be different.

Where f(x) is the target polynomial and q(x) are the quotient polynomial.

because f(b) = 0, So,

f(x)= (x-b) q(x)+f(b)

The slope-intercept definition of a linear function is given as follows:

In which:

For the graph that has a slope of -2/3 and a y-intercept of 2, we have that:

The y-intercept and the slope of the equation y = 0.5x - 1 is given as follows:

-1, meaning that the function passes through the point (0,-1).

When x = -2, the value of the function is given as follows:

y = 0.5(-2) - 1

y = -1 - 1

y = -2.

Hence the other point is (-2,-2).

For the relation in item 3, we have that when x increases by 3, y decays by 6, hence the slope m is given as follows:

m = -6/3

m = -2.

Hence:

y = -2x + b.

When x = 2, y = 54, hence the intercept b is given as follows:

54 = -2(2) + b
