Answer:

It is clear that both equations are identical. Hence, the solution to the system of equations would contain infinitely many solutions.

Step-by-step explanation:

Given the system of equations

y = -4x + 2

y = -4x + 2

It is clear that both equations are identical. We know that when the system of equations is identical, then the system of equations will have infinitely many solutions.

Hence the given system of equations would contain infinitely many solutions.

solving the system of equations

[tex]\begin{bmatrix}y=-4x+2\\ y=-4x+2\end{bmatrix}[/tex]

Substitute y = -4x+2

[tex]\begin{bmatrix}-4x+2=-4x+2\end{bmatrix}[/tex]

For y = -4x+2

Express y in terms of x

[tex]y=-4x+2[/tex]

Thus, the solution to the system of equations would be:

[tex]y=-4x+2,\:x=x[/tex]

It is clear that x = x is true no matter what. Hence, the solution to the system of equations would contain infinitely many solutions.

Answer:

The inequality -5 - 4w > 10 is the TRUE option.

Step-by-step explanation:

Given

w = -4

To determine

We have to determine which inequality is true

Let us substitute w = -4 one by one in all the inequalities

2 - w < -3

substitute w = -4

2 - (-4) < -3

2+4 < -3

6 < -3

FALSE!

Reason: 6 can not be less than -3

-3 - 5w < -14

substitute w = -4

-3 - 5(-4) < -14

-3 + 20 < -14

17 < -14

FALSE!

Reason: 17 can not be less than -14

1- 2w > 13

substitute w = -4

1 - 2(-4) > 13

1+8 > 13

9 > 13

FALSE!

Reason: 9 can not be greater than 13

-5 - 4w > 10

substitute w = -4

-5 - 4(-4) > 10

-5 + 16 > 10

11 > 10

TRUE!

Reason: 11 is indeed greater than 10.

Thus, the inequality -5 - 4w > 10 is the TRUE option.

isosceles right

because A light ray incident at 90° at the first face emerges at the same angle. The diagram shows five isosceles right-angled prisms. A light ray incident at 90° at the first face emerges at the same angle with the normal from the last face.

Answer:

13

Step-by-step explanation:

the top angle is 45°, and then there is the 90° angle, so the other angle must also be 45°. this makes it a right isosceles triangle, so both legs must be equal (they are both 13)

Answer:

Step-by-step explanation:

Answer:

First, let's do a fast definition of a function.

A function is a relation that maps elements from a given set (the domain, is the set of the inputs, usually represented with the variable x) into elements of another set (the range, which is the set of the outputs, usually represented with the variable y)

The functions can map each element of the domain into only one output.

Now, let's solve the problem:

For the vertical table, we can see that the values of x are:

{1, 2, 3} This is the domain.

And the values of y are:

{4, 6, 8} This is the range.

This relation represents a function.

For the horizontal table, we can see that:

The inputs are:

{4, 5}  (notice that the 4 is two times there) This is the domain.

And the outputs are:

{2, 3, 4} This is the range.

Here we can see that this relationship maps the input "4" into two different outputs, then this is not a function.

2)  We want to know if the graph represents a function.

The first thing we can see is that if we draw a vertical line in some places, the line will touch the graph at two different points. This means that one single value of x can be mapped into two different values of y.

And as we already said, a function maps each input into only one output, then the graph does not represent a function.

For x/2 to be greater than or equal to 10, you must try out a few numbers.

If x = 20...

x/2 greater than or equal to 10

= 20/2 greater than or equal to 10

= 10 greater than or equal to 10.

So the answer for x is:

x = 20 or more

The area of the circle is around 908 square centimeters, so the correct option is A.

The area of a circle of radius R is given by:

A = pi*R²

Where pi is an irrational number, and we can write it as pi = 3.14

Here we can see that the radius of the circle is 17cm, then we can replace that in the area formula to get:

A = 3.14*(17cm)² = 908 cm²

Then the corret option is A.

Answer:

1. 5

2. [tex]\sqrt{85}[/tex]

3. [tex]\sqrt{26}[/tex]

Step-by-step explanation:

1. just count the units: 5 units

2. Find the slope = rise/run = -7/6

you now have a right triangle, one side is 7 units (from the rise), and the other is 6 units (from the run)

use the pythagorean theorem to find the hypotenuse.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]7^{2} + 6^{2} = c^{2}[/tex]

49 + 36 = [tex]c^{2}[/tex]

85 = [tex]c^{2}[/tex]

[tex]\sqrt{85} = \sqrt{ c^{2}[/tex]

[tex]\sqrt{85} = c[/tex]

Simplify the radical, but [tex]\sqrt{85}[/tex] is farthest that it can go, so that is the answer.

3. same process as 2

slope = -1/5

[tex]1^{2} + 5^{2} = c^{2}[/tex]

1 + 25 = [tex]c^{2}[/tex]

26 = [tex]c^{2}[/tex]

[tex]\sqrt{26} = c[/tex]

That is the farthest it can go, so that will be the answer.

Answer:

Please check the attached graph.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the equation

[tex]y = 4x[/tex]

Here:

x represents the distance x the tortoise 'runs' in miles for y miles the hare runs.

comparing with the slope-intercept form of the line equation

The graph of the function is attached below.

As the hare runs 16 miles, so

y = 16 miles

so substitute y = 16 in the equation

y = 4x

16 = 4x

switch sides

4x = 16

divide both sides by 4

4x/4 = 16/4

x = 4

Therefore, when the hare runs 16 miles, the tortoise will run only 4 miles.

Answer:

V≈653

Step-by-step explanation:

In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)

Answer:

653in

Step-by-step explanation:

Radius = 4

Height = 13

Volume = 653

Bottom and top Surface Area = s (50 for 1) (100 is both)

Total Surface Area

= 13 + 50 + 50 = 100 + 2(100) = 100(13+4)

Answer:

1) 4.2 inches

2) 63 inches²

Step-by-step explanation:

If the base is 15 inches, we can assume that the opposite side is also 15 inches. 15 + 15 = 30. If we subtract 30 from the total perimeter, we will have the sum of the last two sides.

38.4 - 30 = 8.4

Now that we have the sum we can now find the exact length with division:

8.4/2 = 4.2 inches

To find the area, we multiply these together.

4.2 * 15 = 63

Answer:

32 pounds of almonds

Step-by-step explanation:

Let the number of pounds of almond be a while that of cashews be c

we want to make a total of 80 pounds

Thus;

a + c = 80 ••••••••(i)

Furthermore;

Let us work with the costs

Costs of a pounds of almonds will be ;

a * 2.5 = 2.5a

cost of c pounds of cashews

c * 3.25 = 3.25c

Total cost at which they sell will be 80 * 2.95 = 236

Thus;

3.25c + 2.5a = 236 •••••(ii)

From i, c = 80-a

Put this into ii

3.25(80-a) + 2.5a = 236

260-3.25a + 2.5a = 236

0.75a= 24

a = 24/0.75

a = 32

Answer:

Not parallel.

Step-by-step explanation:

It would be parallel if its slope is also 3.

Calculate slope of line AB = y2 - y1 / x2 - x1

8 - (-2) / 3 - (-1) =

8 + 2 / 3 + 1 = 10/4 = 2.5

2.5 =/= 3, it wouldn't be parallel.

The line AB passing through the points A(- 1, - 2) and B(3, 8) is not parallel to a line having a slope of 3.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, Line AB passes through the points A(-1, -2) and B(3, 8).

We know lines parallel to each other have the same slope.

Therefore, The line passes through the points  A(-1, -2) and B(3, 8).

Slope(m) = (8 + 1)/(3 + 1).

Slope(m) = 9/4.

So, The AB is not parallel to a line having a slope of 3.
