The system of linear equations x - y = 7 and 0.5x + y = 5 can be solved by first rearranging into y = mx + b form and graphing. Intersecting point of the two lines is the solution. In such equations, y is the dependent variable, relying on x, the independent variable.

You've been asked to solve the system of linear equations by graphing. The pair of equations you're given are: x - y = 7, and 0.5x + y = 5. Let's start by expressing these equations in the form y = b + mx.

For x - y = 7, you can rearrange it as y = x - 7 where the slope (m) is 1 and the y-intercept (b) is -7.

For 0.5x + y = 5, you can rearrange it as y = -0.5x + 5 where the slope (m) is -0.5 and the y-intercept (b) is 5.

Now you must graph these two lines on the same graph. Where these two lines intersect, that is the solution of the system of equations.

When graphing these lines, start at the y-intercept (b) and use the slope (m) to find additional points. The slope is a ratio representing the vertical change in y for each unit of horizontal change in x.

Expressing Equations Graphically in this way can help visually solve the system of equations.

Also note that, in each equation, y is the dependent variable since its value relies on the value of x, the independent variable.

Emily Ruth's annual premium is $1058.50

Step-by-step explanation:

Emily Ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

From the given table,

For females, the age of a male 3 years younger should be used.

So, we have to check for 24 year male for 20 year endowment.

It is 42.34 for every $1000 face value.

For a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ Emily Ruth's annual premium is $1058.50

Answer:

Sides of FE = 8 units.

Step-by-step explanation:

Median of any triangle is the line segment that joins any vertex of the triangle with the mid-point of its opposite side.

In the given figure, the median from G meets the mid-point of the opposite side FE, at point T.

Since, GT is the median of ΔFGE and it bisects the side FE into two halves where FT=TE

Given: TE = 8 units.

FE = FT + TE

Since, FT = TE

FE = 2 TE = 2(8) = 16 units.

Therefore, the sides of FE = 8 units.

Answer:

Ram will get 10 chocolates

Step-by-step explanation:

It the chocolates are shared in the ratio of 1 to 3 then the total is 4

Ram : I

1:3  

1+ 3 = total

1+ 3 =4

Our total is 40, but the ratio stays the same, we just add the variable x to the 1 and the 3

1x+ 3x =40

Combine like terms.

4x = 40

Divide each side by 4

4x/4 = 40/4

x =10

So ram will get 1 * 10 = 10 and you will get 3 * 10 = 30

1. For the function f(x) = x^2 + 2x + 3:

a) f(-x) = x^2 - 2x + 3

b) -f(x) = -x^2 - 2x - 3

c) -f(-x) = -x^2 + 2x - 3

2. For the function g(x) = 55/x + 3x:

a) g(-x) = -55/x - 3x

b) -g(x) = -55/x - 3x

c) -g(-x) = 55/x + 3x

For both functions f and g, we found the values of f(-x), -f(x), -f(-x), g(-x), -g(x), and -g(-x) by substituting -x into the original functions and negating the functions where necessary.

1. For the function f defined by f(x) = x^2 + 2x + 3:

a) To find f(-x), we substitute -x into the function:

f(-x) = (-x)^2 + 2(-x) + 3 = x^2 - 2x + 3

b) To find -f(x), we negate the entire function:

-f(x) = -(x^2 + 2x + 3) = -x^2 - 2x - 3

c) To find -f(-x), we substitute -x into the negated function:

-f(-x) = -((-x)^2 + 2(-x) + 3) = -x^2 + 2x - 3

2. For the function g defined by g(x) = 55/x + 3x:

a) To find g(-x), we substitute -x into the function:

g(-x) = 55/(-x) + 3(-x) = -55/x - 3x

b) To find -g(x), we negate the entire function:

-g(x) = -(55/x + 3x) = -55/x - 3x

c) To find -g(-x), we substitute -x into the negated function:

-g(-x) = -(-(55/(-x)) + 3(-x)) = -(-55/x - 3x) = 55/x + 3x

the main difference between a square and a rectangle is that a square has all sides of equal length, while a rectangle has opposite sides of equal length and adjacent sides of different lengths.

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

• Heptagon

• Octagon

• Nonagon

Given, a polygon is a square, then all 4 angles are right. If all 4 angles of a polygon are right, then it is a rectangle.

A square is a special case of a rectangle where all four sides are of equal length. So, a square is a rectangle with all right angles and all sides of equal length.

On the other hand, a rectangle is a four-sided polygon with all four interior angles equal to 90 degrees.

However, in a rectangle, the opposite sides are parallel, and the adjacent sides are of different lengths.

In summary, the main difference between a square and a rectangle is that a square has all sides of equal length, while a rectangle has opposite sides of equal length and adjacent sides of different lengths.

Step-by-step explanation:

Note that for the "leaf" or the right side, it is only the one's place value. The left side, or the "stem" contains the tens place as well as anything greater.

124 in a stem-and-leaf plot is seen as: 12 | 4, in which 12 is your stem, and 4 is your leaf.

~

Answer:

12 is the stem

Step-by-step explanation:

The last digit ( or the ones place) is the leaf.  Everything else is the stem

So for 124, the ones digit is the leaf.   4 is the leaf

Everything else is the stem  12 is the stem

Answer:

The solution is (-5,4).

Step-by-step explanation:

We are given the equation, |x+1|=|-x-9|

Now, |x+1| = [tex]\left\{\begin{matrix}x+1 & ,x>0\\ -(x+1)& ,x<0\end{matrix}\right.[/tex]

Also, |-x-9| = [tex]\left\{\begin{matrix}-x-9 & ,x>0\\ -(-x-9)& ,x<0\end{matrix}\right.[/tex]

So, equating these two functions gives the value of x = -5. After substituting this value in any of the function term say y = x+1, we get y = 4.

Moreover, from the graph below we see that, after equating these functions, the solution is given by the points at which they intersect.

Hence, the solution is (x,y) = (-5,4).

Answer:

$2.14

Step-by-step explanation:

First, set up a proportion.

x over 3.29 equals 35 over 100.

You are trying to find what out of 3.29 is 35 percent.

Cross multiply and divide.

3.29 times 35 = 115.15

115.15 divided by 100 = 1.1515

Round to the nearest hundredth because you are dealing with money.

$1.15

Because you are looking for the sale price, you must add or subtract $1,15 from the original amount which is $3.29.

In this case, you must subtract because it is a markdown. You are taking an amount off of the original price.

$3.29 - $1.15 = $2.14

The final price is 2 dollars and 14 cents

Answer:

Step-by-step explanation:

For shirt :

Original cost = $54

New cost = $18

Change amount = 54 - 18 = $36

% INC/DEC = (36 /54) * 100 = 2 * 100 / 3 = 66.66%

For PS4 :

Original cost =$400

New cost = $250

Change in amount = 400- 250 =$150

% INC/DEC = (150/400) * 100 = 37.5%

For Coffee maker:

Original cost = $30

New cost = $20

Change in amount = 30 - 20 = $10

% INC/DEC = (10/30)*100 = 33.33 %

For Luggage:

Original cost = $180

New cost = $50

Change in amount = 180 - 50 = $130

% INC/DEC = (130/180)*100 = 72.22 %

Answer:

x and y do not show direct variation.  

Step-by-step explanation:

The formula for direct variation is

y = kx     Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y do not show direct variation.

Answer:x and y do not show direct variation.  

Step-by-step explanation:

Step-by-step explanation:

To solve 924 ÷ 4, we simply divide 924 by 4. So, 924 divided by 4 equals 231.

When we're dividing one number by another, we're essentially figuring out how many times the divisor (the number you're dividing by) fits into the dividend (the number you're dividing).

In this case, we're dividing 924 by 4. We start by asking ourselves, "How many times does 4 fit into 9?" Since 4 doesn't fit into 9 evenly, we move to the next digit and consider 92. 4 fits into 92 twenty-three times (4 x 23 = 92).

Then, we subtract 92 from 924, which leaves us with 32. Now, we bring down the next digit, which is 4, and we consider how many times 4 fits into 324. 4 fits into 32 eight times (4 x 8 = 32).

So, we've found that 4 fits into 924 exactly 231 times without any remainder. Therefore, 924÷4=231.
