The solution of the system of equation using elimination method is x = -2, y = -4

The elimination method is a method used to solve systems of linear equations. It involves manipulating the equations in such a way that one of the variables is eliminated, resulting in an equation in one variable that can be easily solved.

-2y = 2 - 3x --- (1)

-5y = 10 - 5x ---(2)

To eliminate y, multiply (1) by -5 and multiply (2) by -2. Then subtract the result. That is:

-5 × (-2y = 2 - 3x)   =>  10y = -10 + 15x

-2 ×(-5y = 10 - 5x)    => 10y = -20 + 10x

.......................................................................

                                      0 = 10 +5x

.........................................................................

0 = 10 +5x

5x = -10

x = -10/5

x = -2

put x = -2 in (1):

-2y = 2 - 3x

-2y = 2 -3(-2)

-2y = 2 + 6

-2y = 8

y = -8/2

y = -4

Thus, x = -2, y = -4

A chocolate frog costs $0.35. The result is obtained by using elimination and substitution method.

To eliminate equations, we can either add or subtract the equations. Substitution is substituting the value of one variable in the other equation.

We have

Find the cost of a chocolate frog!

Let's say

We rewrite the problem mathematically.

A = 15 cents + B ... (equation 1)

3B + 2A = $1.30 ... (equation 2)

We know that $1 = 100 cents. Multiplied by 2, the equation 1 will be

2A = 30 cents + 2B

2A = $0.3 + 2B ... (equation 3)

We eliminate the equation 1 and 3.

3B + 2A = $1.30

2A - 2B = $0.3 _

5B = $1.0

B = $0.2

We substitute the value of B in equation 3.

2A - 2B = $0.3

2A - 2($0.2) = $0.3

2A - $0.4 = $0.3

2A = $0.7

A = $0.35

Hence, the cost of a chocolate frog is $0.35.

Answer:

Step-by-step explanation:

To find out how much the man spent per shirt, you need to divide the total cost of the shirts by the number of shirts.We know that the man spent $250 on the suit and $398 on the four shirts. To find the total cost of the shirts, you can add these two amounts:$250 + $398 = $648To find the cost per shirt, you need to divide the total cost of the shirts by the number of shirts:$648 / 4 = $162So the man spent $162 per shirt.

If f(3) = 3 - |2x - 5| is given then the value of f(0) + f(-4) would be -8.

What is the function?

A function is a mathematical relationship between a set of inputs (also known as domain) and a set of possible outputs (also known as range). The inputs are usually represented by variables, such as 'x' in the examples you provided.

To find f(3), we need to plug in x = 3 into the equation:

f(3) = 3 - |2(3) - 5| = 3 - |6 - 5| = 3 - |1| = 3 - 1 = 2

To find f(0), we need to plug in x = 0 into the equation:

f(0) = 3 - |2(0) - 5| = 3 - |-5| = 3 - 5 = -2

To find f(-4), we need to plug in x = -4 into the equation:

f(-4) = 3 - |2(-4) - 5| = 3 - |-9| = 3 - 9 = -6

Now we can add f(0) + f(-4) = -2 + (-6) = -8

Hence, if f(3) = 3 - |2x - 5| is given then the value of f(0) + f(-4) would be -8.

The description of the piecewise function y is -2x + 3.

It is necessary to optically estimate the coordinates of the points because not everything is visible (particularly for the leftmost point).

the basic function definition appears on all three segments.

y = ax + b

X is always a factor of a, which is the line function's slope.

When a point on a line moves from one end to the other, the ratio y/x shows how many units change when x moves by a specific number of units.

b represents the y-intercept, or the value of y when x = 0.

(-6, 1.5) is followed by the first part and then (-3, 3).

x is modified by +3 units (from -6 to -3).

y shifts by 1.5 or 3/2 units (from 1.5 to 3).

the line has a slope of 3/2/3, which is 3/(23) = 1/2.

supplying the initial portion

y = (1/2)x + b

When we solve for b using a single point's coordinates (for example, -3, 3), we obtain b:

6/2 + 3/2 = b

A factory produces 72 bottles of juices in one minute.

Meaning of rate:

A rate is a special ratio in which two words are expressed using different units. The price is $69 for 12 ounces of corn if a 12-ounce can costs that much. This is not a ratio of two comparable units, like shirts, for example. This is a ratio between the units of cents and ounces.

We must divide the quantity of bottles produced by the time it takes to make them in order to determine the factory's production rate in bottles per minute. The factory in this instance produced 360 bottles in 5 minutes, resulting in the following production rate:

= 360 bottles / 5 minutes

The seller ought to bring more medium-sized shirts because these are the best-selling size.

From the graph we can see that total small shirt sold = 160

Total number of sale of small shirt = 225

Now remaining shirts = Total small shirt sold/Total number of sale

Now remaining shirts = 160/225 × 100

Now remaining shirts = 71

Total medium shirt sold = 335

Total number of sale of medium shirt = 375

Now remaining shirts = Total shirt sold/Total number of sale

Now remaining shirts = 335/375 × 100

Now remaining shirts = 89

Total large shirt sold = 275

Total number of sale of large shirt = 325

Now remaining shirts = Total shirt sold/Total number of sale

Now remaining shirts = 275/325 × 100

Now remaining shirts = 85

Total X-large shirt sold = 125

Total number of sale of X-large shirt = 175

Now remaining shirts = Total shirt sold/Total number of sale

Now remaining shirts = 125/175 × 100

A classification system can be expressed mathematically using a decision boundary. This boundary is defined by a decision function that maps the input data to a discrete output. The decision boundary is determined by setting a threshold for the output of the decision function, such that if the output exceeds the threshold, the predicted class is labeled as a "positive" output and if the output is below the threshold, the predicted class is labeled as a "negative" output.

The output of a regression system is usually a continuous value, which represents the predicted result of the model. A regression system can be expressed mathematically using a linear equation which maps the input data to a continuous output. The equation is determined by fitting a line to the data, such that the line best fits the data points.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Therefore, let's solve the equation as follows:

3(2x - 7) = 3

open the bracket

3(2x - 7) = 3

6x  - 21 = 3

add 21 to both sides of the equation

6x  - 21 = 3

6x  - 21 + 21 = 3 + 21

6x = 24

divide both sides by 6

6x / 6 = 24 / 6
