Find the x−and y−intercepts. −2x − 5y = 20

Answers

Answer 1

Answer:

X=10, Y=4

Step-by-step explanation:

Along the y-axis, x = 0.

2(0) + 5y = 20

5y = 20

y = 4

Your y-intercept is at (0,4).

Along the x-axis, y = 0

2x + 5(0) = 20

2x = 20

x = 10

Your x-intercept is at (10,0).

Answer 2

Answer:

-2x-5y=20 (if x= 2 )

[tex] - 2 \times 5 - 5 \times y = 20 [/tex]

[tex] - 20 - 5 \times y = 20[/tex]

[tex] - 5 \times y = 40[/tex]

[tex]y = 8[/tex]

If the distance of P x, y from the points A (3, 6) and B −3, 4 are equal, prove that
3x + y = 5

Answers

Answer:

See Below.

Step-by-step explanation:

We are given a point P(x, y). It is equidistant from A(3, 6) and B(-3, 4).

So, let's first determine the distance from P to each point. We can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Segment PA:

We will let P(x, y) be (x₂, y₂) and A(3, 6) be (x₁, y₁). By substitution:

[tex]d=\sqrt{(x-3)^2+(y-6)^2[/tex]

This represents the distance from P to A.

Segment PB:

Again, we will let P(x, y) be (x₂, y₂) and B(-3, 4) be (x₁, y₁). By the distance formula:

[tex]d=\sqrt{(x-(-3))^2+(y-4)^2}[/tex]

We may simplify:

[tex]d=\sqrt{(x+3)^2+(y-4)^2}[/tex]

Now, we know that the two distances are equivalent. Hence:

[tex]\sqrt{(x-3)^2+(y-6)^2}=\sqrt{(x+3)^2+(y-4)^2[/tex]

Simplify. Square both sides:

[tex](x-3)^2+(y-6)^2=(x+3)^2+(y-4)^2[/tex]

Square:

[tex](x^2-6x+9)+(y^2-12x+36)=(x^2+6x+9)+(y^2-8x+16)[/tex]

Subtract all terms from the right:

[tex](x^2-6x+9)-(x^2+6x+9)+(y^2-12x+36)-(y^2-8x+16)=0[/tex]

Distribute the negative:

[tex][(x^2-6x+9)+(-x^2-6x-9)]+[(y^2-12y+36)+(-y^2+8y-16)]=0[/tex]

Rearrange:

[tex][(x^2-x^2)+(-6x-6x)+(9-9)]+[(y^2-y^2)+(-12y+8y)+(36-16)]=0[/tex]

Combine like terms;

[tex](-12x)+(-4y)+(20)=0[/tex]

We can divide both sides by -4:

[tex]3x+y-5=0[/tex]

Finally, adding 5 to both sides produces:

[tex]3x+y=5[/tex]

The function y=-0.25+1 represents the percent y (in decimal form)  A battery power remaining x hours after you turn on the laptop computer. Identify and interpret the slope.

The slope is ___. This means that the power ____ by ____ per hour

Answers

Answer:

The slope is -0.25. This means that the power reduces by 0.25 percent per hour

Step-by-step explanation:

Given

[tex]y = -0.25x + 1[/tex]

Required

Identify and interpret the slope

An equation has a general form:

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

Where

[tex]m = slope[/tex]

Compare [tex]y = mx + b[/tex] to [tex]y = -0.25x + 1[/tex]

We have:

[tex]mx = -0.25x[/tex]

Divide both sides by x

[tex]\frac{mx}{x} = \frac{-0.25x}{x}[/tex]

[tex]m = \frac{-0.25x}{x}[/tex]

[tex]m = -0.25[/tex]

Because the result of the above calculation is negative, it means that the function reduces

The given function measures the percentage of power by hour.

So, the power reduces by 0.25% per hour

24 grams of salt and 16 grams of pure water were added to 160 grams of a 35% solution. What is the percentage of salt in the new solution?

Answers

Hi I know the answer it is 67

Answer: 40%

Steps are below

Step-by-step explanation:

First, let's find the amount of salt. 160/100=1.6, then 1.6x35 is 56. So the current amount of salt before we add more salt is 56g. Now that we know the amount of salt, let's find the amount of water. The total amount of solution is 160g, 56g of that is salt, and the rest is pure water. 160-56= 104g of pure water. Let's add 24 grams of salt and 16 grams of pure water. We now have 80g of salt, and 120g of water. A common mistake is doing 80/120, WHICH IS INCORRECT. The correct formula for solution/concentration is the amount of substance/total amount of solution. So you'd do 80+120 to get 200, and then do 80/200 which gets you 40%.

66 cm cube of silver is drawn into a wire 1 mile in a diameter does length of wire will be​

Answers

Answer:

The length of the wire is 3.24451394 × 10⁻⁹ cm

Step-by-step explanation:

The volume of the wire = 66 cm³

The diameter of the wire = 1 mile

We convert the volume from cm³ into mile³  to get;

66 cm³ = 1.5834 × 10⁻¹⁴ mile³

The volume = π × D²/4 × l

Where;

D = The diameter = 1 mile

l = The length of the wire

1.5834 × 10⁻¹⁴ = π × 1²/4 × l

The length of the wire = l = 1.5834 × 10⁻¹⁴/(π × 1²/4) = 2.0160475 × 10⁻¹⁴ mile

1 mile = 160,934.4 cm

2.0160475 × 10⁻¹⁴ mile = 2.0160475 × 10⁻¹⁴ × 160,934.4 cm = 3.24451394 × 10⁻⁹ cm  

The length of the wire = 3.24451394 × 10⁻⁹ cm

Answers

Answer:

The area of one rectangle is 15 cm²

Step-by-step explanation:

The given parameters are;

The area of the square = 64 cm²

The length of the rectangles = 5 cm

The formula for the area of a square = (Side length)² = S²

Therefore, whereby the side length of the given square = S, we have;

Area of the square = 64 = S × S = S²

S = √(64 cm²) = 8 cm

The side length of the square = 8 cm

The perimeter of a square = The length of the string = Side length × 4 = 8 cm × 4 = 32 cm

∴ The perimeter of a square = The length of the string = 32 cm

The length of the string = The perimeter of the two congruent rectangle = 32 cm

Therefore;

The perimeter of each rectangle = 32/2 cm = 16 cm

Given that the length, L of the side of each rectangle is L = 5 cm, we have;

The perimeter of a rectangle = 2 × L + 2 × W

Where;

W = The width

The perimeter of the rectangle = 16 = 2 × 5 + 2 × W

2 × W = 16 - 2 × 5 = 6

W = 6/2 = 3

W = 3 cm

The width, W, of each rectangle is W = 3 cm

The area of one rectangle = W × L = 3 cm × 5 cm = 15 cm²

The area of one rectangle = 15 cm².

Some steps to construct an angle MNT congruent to angle PQR are listed below.

Step 1: Draw a segment NT.
Step 2: Use a compass to draw an arc from point Q that intersects the side PQ of angle PQR at point A and the side QR at point B.
Step 3:
Step 4: Adjust the width of the compass to AB, and draw an arc from point X such that it intersects the arc drawn from N in a point Y.
Step 5: Join points N and Y using a straightedge.

Which statement describes step 3 correctly?

Use the same width of the compass to draw an arc from point T that intersects the segment NT at a point X.
Use the same width of the compass to draw an arc from point N that intersects the segment NT at a point X.
Use the same width of the compass to draw an arc from point A that intersects the segment NT at a point X.
Use the same width of the compass to draw an arc from point B that intersects the segment NT at a point X.

Answers

From the description of the construction of the congruent angle, we have;

The statement that describes step 3 correctly is; Use the same width of the compass to draw an arc from point N that intersects the segment AN at a point X

The reason for making the above selection is as follows:

The steps to construct an angle congruent to another angle are;

Step 1: Given an angle PQR, draw a working segment NT

Step 2: Place the needle of the compass at point Q and draw an arc (Q, QA), intersecting sides PQ and QR of the angle ∠PQR at points A and B respectively

Step 3: Place the needle of the compass at point N and draw an arc with the compass width QA from above the to intersect the segment NT at a point X

Step 4: Set the compass width to the distance AB with which an arc is drawn from point X so as to intersect the arc (N, QA) above at point Y

Step 5: The points Y and N are joined with a straight line to form the congruent angle

Analysis of the steps:

Given that in step 4, we have that the the arc drawn from point X with compass width AB is meant to intersect the arc drawn from point N, at point Y, we have that in step 3 an arc was drawn from point N with compass width QA from step 2 to intersect NT at a point X

Therefore;

Step 3 is best described by the following statement;

Use the same width of the compass to draw an arc from point N that intersects the segment AN at a point X

Use the same width of the compass to draw an arc from point N that intersects the segment NT at a point X.

This option gives us the step 3.

This is because we want to have equal angles. Therefore we select an arc equal in length to arc AB which intersects NT at  point X.
