Answer:

It means two lines intersected.

C is correct

Hope this helps!

:)

If a system of linear equations has one solution, this means that the lines are intersecting lines

Intersecting lines are lines that meet at a point.

For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution

For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation

Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

Answer:

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

[tex]\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4[/tex]

Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]

Answer: 6

Step-by-step explanation: Let n represent the number of twelfths in 5/4. Expressed symbolically, this is n/12 = 2/4. The LCD is 12. Multiply numerator and denominator of 2/4 by 3, obtaining: n/12 = 6/12 then n = 6. There are 6 twelves in 2/4.  

There are 6 twelfths equal two fourths.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

We have to find twelfths equal two fourths

Let x represent the number of twelfths in 5/4.

So, the mathematical expression is

x/12 = 2/4.

Now, simplifying the fraction

x/ 12= 1/2

Now, multiply both side by 12

12 x/12 = 12/2

x= 6

Hence, there are 6 twelfths .

Answer:

(2, 3) x=2, y=3

Step-by-step explanation:

There are two ways to solve this: substitution & elimination:

Using substitution for this equation:

[tex]\left \{ {{3x+y=9} \atop {5x+4y=22}} \right.[/tex]

3x + y =9

y = 9-3x

Substitute for y:

5x + 4(9 - 3x) = 22

5x + 36 - 12x = 22

-7x = -14

x = 2

Solve for y:

3(2) + y = 9

6 + y = 9

y = 3

Step-by-step explanation:

Original amount: $4230

Interest for 1 year: 4.2%

First year;

[tex]4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66[/tex]

Second year;

The graph is a linear and straight line so option (B) will be correct.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

Given graph is ;

y = 2x - 3

The slope of any function is given by;

dy/dx

So,

d(2x - 3)/dx = -2

Since the slope is constant that it will be a straight line and the straight line curve is a linear function because it has a degree of 1.

Hence "The graph is a linear and straight line".

Answer:

Step-by-step explanation:

Use FOIL method

(3√2 +  4)(√2 - 1) = 3√2*√2 - 3√2*1 + 4 *√2 - 4*1

                           =3*√(2*2) - 3√2 + 4√2 - 4

                           = 3*2 - 3√2 + 4√2 - 4

                           = 6 - 3√2 + 4√2 - 4  {add the like terms}

                          = 6 - 4 - 3√2 + 4√2
