The system of equation 3(-y + 7) = 3(y + 5) + 6 has,

B. The equation has one solution.

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

The given system of equation is 3(-y + 7) = 3(y + 5) + 6.

- 3y + 21 = 3y + 15 + 6.

- 3y + 21 = 3y + 21.

Now,

b₁/b₂ ≠ a₁/a₂, So the system of the equation has a unique solution which is at  (0, 21).

The value of (f.g)(x) is x³/2 + x².

What is multiplication?

Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product.

Here, we have

Given

f(x) =x²+2x and g(x)= 1/2x.

We have to find the value of (f⋅g)(x).

We apply multiplication and get

(f.g)(x) = (x²+2x)1/2x

(f.g)(x) = x²×1/2x + 2x×1/2x

(f.g)(x) = x³/2 + x²

Hence, the value of (f.g)(x) is x³/2 + x².

Answer:

16.1 cm (nearest tenth)

Step-by-step explanation:

Pythagoras’ Theorem

\(a^2+b^2=c^2\)

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

Substitute the given values into the formula and solve for c:

\(\implies 16^2+2^2=c^2\)

\(\implies 256+4=c^2\)

\(\implies c^2=260\)

\(\implies c=\sqrt{260}\)

\(\implies c=2\sqrt{65}\)

\(\implies c=16.1 \sf \: cm\:(nearest\:tenth)\)

16.1 is rounded to the nearest tenth

The table that correctly shows these ratios in a three-column table is shown below:

Classroom Brown      Green

1                     10         18

2                     12         23

3                          15        35

4                          32         64

The correct three-column table would be:

Classroom    Brown            Green

1                        5                  9

2                     12/2              23/2

3                       3/7                 5/7

4                       1/2                   1/2

To create the table, we can simplify each ratio by dividing both the numerator and denominator by their greatest common factor. For example, in Classroom 1, the greatest common factor of 10 and 18 is 2, so we can divide both by 2 to get the simplified ratio of 5:9.

Similarly, for Classroom 2, we divide both the numerator and denominator by 2 to get 6:23/2 or 12:23. We can simplify the remaining ratios in the same way.

Answer:

50 degrees

Step-by-step explanation:

Triangle = 180

180 - 90 = 90

? = 50 degrees

Answer:

(a) Because the expression is not an equation

(b) Because the expression is an equation

Step-by-step explanation:

Solving (a): a + 2

The above expression can assume any value for a because it is not an equation.

Take for instance:

a = 2;

\(a + 2 \to 2 + 2 = 4\)

\(a =-4\)

\(a + 2 \to -4 + 2 = -2\)

The reason for this is because the expression is not an equation

Solving (b): \(b + 2 = 5\)

The above expression can assume only value for b, and the value is:

\(b + 2 = 5\)

\(b = 5-2\)

\(b =3\)

This means that only \(b =3\) will make the equation true.

The reason for this is because the expression is an equation

Answer:

12x+7<−11       x < - 1.5

5x−8≥40        x ≥ 9.6

Step-by-step explanation:

12x+7<−11    First, move the constant to the right. 12x < -11 - 7 Then, we can get the total value and then divide everything by 12. 12x < -18    ->   x < - 1.5

5x−8≥40    Move the constant to the right. 5x ≥ 40+8 Then, after we add the constants, we can divide both sides by 5. 5x ≥ 48     ->       x ≥ 9.6

The number of points gained overall by Julia playing the game is 30 point

From the question, we have the following parameters that can be used in our computation:

Tax paid for a new quest = 2.5 points

Total points gained playing the game = 75 points

The above parameters can be represented as

The number of points gained overall = Total points gained playing the game/Tax paid for a new quest

Substitute the known values in the above equation, so, we have the following representation

The number of points gained overall = 75/2.5

Express as a correct fraction

So, we have the following representation

The number of points gained overall = 750/25

Evaluate the quotients

So, we have the following representation

The number of points gained overall = 30

Hence, the number of points gained overall =is30

Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?

Number of yards bought = 3/8

Cost of a yard = Phone 72.00

Cost of number of yards bought = Number of yards bought × Cost of a yard

= 3/8 × Php 72.00

= Php 27.00

She gave Php 1000.00 to the cashier.

How much change will she?

= Amount given to the cashier - cost of yards bought

When 'x' is 5, the Algebraic  expression 3x - 4 evaluates to 11.

To find the algebraic expression for "4 less than the product of 3 and some number," let's break it down step by step.

First, let's define the unknown number as 'x.' Since the problem states "the product of 3 and some number," we can express this as 3 * x or simply 3x.

Next, we want to subtract 4 from this product. The phrase "4 less than" indicates subtraction, so we subtract 4 from 3x. This can be represented as 3x - 4.

In summary, the algebraic expression for "4 less than the product of 3 and some number" is 3x - 4, where 'x' represents the unknown number.

To calculate the value of this expression for a specific value of 'x,' you substitute that value into the expression and simplify. For example, if 'x' is 5, you would substitute 5 into the expression:

3(5) - 4

This simplifies to:

15 - 4 = 11

So, when 'x' is 5, the expression 3x - 4 evaluates to 11.

In general, the algebraic expression allows us to represent a mathematical relationship between quantities using symbols and operations. By substituting specific values into the expression, we can calculate the corresponding results.

The solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11). The system has exactly one solution.

Let's solve the system of linear equations correctly.

The given system of linear equations is:

x = y + 3z = 6

x - 2y = 5

2x - 2y + 5z = 9

To determine the number of solutions, we can analyze the system using the method of elimination or substitution. Let's use the method of elimination:

From equation 1, we have:

x = y + 3z

Substituting this value of x in equation 2:

(y + 3z) - 2y = 5

y + 3z - 2y = 5

-z + 3z = 5 - y

2z = 5 - y

Now, let's substitute the value of x in equation 3:

2(y + 3z) - 2y + 5z = 9

2y + 6z - 2y + 5z = 9

11z = 9

Simplifying the equation, we find:

z = 9/11

Now, substituting this value of z back into the equation 2z = 5 - y, we get:

2(9/11) = 5 - y

18/11 = 5 - y

18/11 - 5 = -y

18/11 - 55/11 = -y

-37/11 = -y

y = 37/11

Finally, we can substitute the values of y and z into equation 1 to find the value of x:

x = y + 3z

x = 37/11 + 3(9/11)

x = 37/11 + 27/11

x = 64/11

Therefore, the solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11).

The system has exactly one solution.
