Answer:

Part A:

Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.

Part B:

(3 ,5 ) is the solution to the equations of lines A and B.

Step-by-step explanation:

Part A:

We are required to determine the number of solutions that the pair of equations for lines A and B have. To do this, we shall determine the slope of each line;

A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. The slope is defined as;

(change in y) / (change in x)

The slope of line A is thus;

(2 - 6)/(6 - 2) = -1

A straight line B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.

On the other hand, the slope of line B is;

(6 - 3) / (4.5 - 0) = 2/3

Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.

Part B:

What is the solution to the equations of lines A and B?

We first need to determine the equation of each line;

Line A, the slope was found to be -1 and the line passes through (2,6)

The equation of the line in slope intercept form is;

y = -x + c

6 = -2 + c

c = 8

y = -x + 8

On the other hand, the slope of line B was found to be 2/3 and the line passes through (0,3). Therefore, we have;

y = 2/3x + c

3 = 2/3 (0) + c

c= 3

y = (2/3)x + 3

The graph of these two lines is shown in the attachment below. The lines intersect at (3 ,5 ) which is the solution to the equations of lines A and B.

The graphical solution to a system of linear equations is given by the point of intersection of the two lines representing each equation.

Answer:

This is a Pythagorean triple.

Step-by-step explanation:

In order to find this, use the Pythagorean Theorem to and see if it gives a true statement.

a^2 + b^2 = c^2

15^2 + 20^2 = 25^2

225 + 400 = 625

625 = 625

Since this is a true statement, we know that this is a Pythagorean Triple.

For this case we have that the equation of a line in the slope form intersection is given by:[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut point with the y axis.

In the green graph we observe that[tex]b = 2[/tex], then its equation is [tex]y = 5x + 2[/tex]

We have the slope of the red line substituting two points:

[tex](0,2)\\(-1,0)[/tex]

[tex]m = \frac {0-2} {- 1-0} = 2[/tex]

Thus, the red line has equation[tex]y = 2x + 3[/tex]

Finally, the blue line is [tex]y = 3x + 3[/tex]

Answer:

Green line, y = 5x + 2

Red line, y = 2x + 3

Blue line, y = 3x + 3

Answer:

1 - green line: y = 5x + 2

2 - red line: y = 3x + 3

3 - blue line: y = 2x + 3

Step-by-step explanation:

1 - green line

The graph with the green line is the easiest to match with an equation.

If you look at the graph, you see that when x = 0, the y-value is 2.

There's only one of the given equations that y = 2 when x = 0, the first one.

y = 5x + 2

y = 5 (0) + 2 = 0 + 2 = 2

It's easy to spot, because in the format y = mx + b, the b is the value of Y when x = 0, as we just demonstrated.

2 - Red line

In this case, when x = 0, y = 3.  And there are 2 equations for which it's true... which is normal because the blue line (in next graph) also passes by this point.

Then to know which equation goes with the red line graph, we have two choices...

A. determine the slope (rate of change) of the red line and see if it matches one of the equations.

B. See what value of X yields a value of 0 for Y and see where it would land on the X-axis.

The second method is faster.  If you see on the graph, when y = 0, x = -1

If we take the 2nd equation (y = 3x + 3) and we set the value of y to 0, we have:

0 = 3x + 3

-3 = 3x

x = -1

Which is exactly what we wanted to find.

So, the red line is y = 3x + 3

3. blue line

Well, there's only one answer left (y = 2x + 3), so it's easy... but let's make sure by finding the slope (method A listed for the red line above), in case your teacher would be playing tricks on you.

The slope of a line is the variation of y-value (Δy) divided by the variation of x-value (Δx).

If we take the two points where the blue line crosses the axis, we have (-1.5, 0) and (0,3).

Now, let's calculate the slope:

S = (0 - 3) / (-1.5 - 0) = -3 / -1.5 = 2

And 2 is the slope of the equation y = 2x + 3

So, we're good.

Answer:

Option C.

Step-by-step explanation:

The given function is g(x) = x² - 10x + 2x which is graphed on a coordinate plane.

We have to find the coordinates of the points at which function crosses x-axis.

As we know the points at which function crosses x-axis, y-coordinates will be 0/

In other words, g(x) = 0

So x² - 10 + 24 = 0

     x - 6x - 4x + 24 = 0

     x (x-6) - 4(x - 6) = 0

     (x-4) (x-6) = 0

     x = 4 and 6

So points at x-axis will be (4, 0 ) and ( 6, 0 )

Option C is the answer.

Answer:

5x - 10 = 2 - 2x + 10(x - 3)

Opening the brackets;

5x - 10 = 2 - 2x + 10x - 30

Putting the like terms together;

10x - 5x - 2x = 30 - 10 - 2

3x = 18

x = [tex]\frac{18}{3}[/tex] = 6

Final answer:

To find the value of x in the given equation, rearrange it to standard form, combine like terms, then isolate x to solve for its value.

Explanation:

Solving the equation: 5x-10=2-2x+10(x-3)

1. Rearrange the equation to standard quadratic form: 5x - 10 = 2 - 2x + 10x - 30

2. Simplify and combine like terms: 5x - 10 = -28 + 8x

3. Bring all terms to one side to get: 3x = 18

4. Solve for x: x = 18/3 = 6

Step-by-step explanation:

Existing walkway

 l = 10 ft

w = 4 ft

A₁ = lw = 10 ft × 4 ft = 40 ft²

New walkway

Expanding a measurement by 25 % means that you multiply it by a factor of 1.25.

New length = 10 × 1.25 = 12.5 ft

New width =    4 × 1.25 =   5    ft

A₂ = lw = 12.5 ft × 5 ft = 62.5 ft²

Increase in area

A₂ - A₁ = 62.5 – 40 = 22.5 ft²

The increase in area is [tex]\boxed{\textbf{22.5 ft}^{2}}[/tex]

john because 1 yard is equal to 3 ft, 4x3=12 ft

Final answer:

Jane has more fabric than John with a difference of 24 inches.

Explanation:

To compare the amount of fabric John and Jane have, we need to convert their measurements into the same unit. Since John has 4 yards of fabric and Jane has 120 inches, we need to convert yards to inches or inches to yards.
To convert yards to inches, we know that 1 yard is equal to 36 inches. So, multiplying 4 yards by 36 inches per yard, we get 144 inches of fabric for John.
Comparing the two measurements, we can see that Jane has more fabric with 120 inches compared to John's 144 inches. The difference is 144 inches - 120 inches = 24 inches. Therefore, Jane has 24 inches more fabric than John.

To find the cost of the magazine, represent the cost of each book as 'x'. Use the given information to set up an equation and solve for 'x'.

To find the cost of the magazine, let's represent the cost of each book as 'x'. Since the magazine costs twice as much as each book, we can represent the cost of the magazine as '2x'.

According to the problem, Ryan bought 3 books and a magazine and paid $30. We can write this information as an equation:

3x + 2x = 30

Combining like terms, we get:

5x = 30

To isolate the variable 'x', we divide both sides of the equation by 5:

x = 6

Therefore, each book costs $6 and the magazine costs twice as much, which is $12.

The cost of the magazine is $10.

Let's denote the cost of each book as B and the cost of the magazine as M. According to the given information:

Now, we also know that the magazine costs twice as much as each book, so M = 2B. Substitute M with 2B in the equations:

Now that we know the cost of each book (B = 6), we can find the cost of the magazine (M) using M = 2B:

M = 2 times 5 = 10

So, the cost of the magazine is $10.

Answer:

f(x) = x² + 9x - 22

Step-by-step explanation:

Given that x = 2 and x = - 11 are zeros, then

(x - 2) and (x + 11) are factors

and f(x) equals the product of the factors

f(x) = (x - 2)(x + 11) ← expand factors

f(x) = x² + 9x - 22 ← is a possible function

The quadratic function [tex]\( f \)[/tex] with zeros at [tex]\( x = 2 \) and \( x = -11 \)[/tex] can be written in factored form as: [tex]\[ f(x) = x^2 + 9x - 22 \][/tex]

The standard form of a quadratic function is:

[tex]\[ f(x) = ax^2 + bx + c \][/tex]

To convert the factored form to standard form, we expand the factors:

[tex]\[ f(x) = a(x^2 + 11x - 2x - 22) \] \[ f(x) = a(x^2 + 9x - 22) \] \[ f(x) = ax^2 + 9ax - 22a \][/tex]

[tex]\[ b = 9a \] \[ c = -22a \][/tex]

So, the quadratic function with zeros at [tex]\( x = 2 \) and \( x = -11 \) is:[/tex]

[tex]\[ f(x) = ax^2 + 9ax - 22a \] \[ f(x) = x^2 + 9x - 22 \][/tex]

The first answer choice

A system of equations can be represented by a matrix equation. The coefficients of the equations are used to form the matrixes, which can then be solved simultaneously.

A system of equations can be represented by a matrix equation using the coefficients of the equations. Let's say you have the following system of equations, where 1. 3x + 2y is equal to 9, and 2. 4x + 5y is equal to 6.

We express this system in the form AX=B, where A is the matrix of coefficients, X is the column matrix of variables, and B is the column matrix of constants. So in this case:
A = [[3, 2], [4, 5]]
X = [x, y]
B = [9, 6].

Adding these together, we can form the matrix equation [[3, 2], [4, 5]] [x, y] = [9, 6]. This represents the given system of equations in matrix form.
