Would someone PLEASE help with this and explain how you got the answer I WILL MARK BRAINLIEST

Answer:

Yes, the number of knots is proportional to the number of rows.

Step-by-step explanation:

The number of knots is proportional to the number of rows, because whenever there is a new row then it implies that there is new knot.

Meaning, as the number of rows increases, the number or knots increases. This is a proportional relationship.

Answer:

y=15x+5

Step-by-step explanation:

Answer:

Step-by-step explanation:

use Pythagorean theorem a² + b² = c²

where a = 8

           b = 15

           c = s (which is unknown)

plugin values into the formula:

a² + b² = c²

8² + 15² = s²

s = √(64 + 225)

s = √289

s = 17

Answer: -2.5,   -5.5

Step-by-step explanation:

5x - y= -7

3x - y= -2 multiply by -1

5x - y= -7

-3x + y= +2 we add both equations

2x=-7+2,  2x=-5,   x=5/2= -2.5

5(-2.5)-y=-7

- 12.5-y= -7 we simplify and get

-y=-7+12.5,             -y=5.5,    y=-5.5

m = -3

point = (-4,6)

You need to put this in point slope form.

y - 6 = - 3( x + 4 )

distribute

y - 6 = -3x - 12

add 6 to 12

y = -3x - 6

answer : y=-3x-6

Answer:

(2x^2 + x-7)/3x+ 3

Step-by-step explanation:

Here, we want to write the following as a single fraction;

2x-1/3 - 2/x + 1

That will be;

(2x-1)(x + 1) -2(3)/3(x+ 1)

= 2x^2+ 2x-x-1-6/3(x + 1)

= (2x^2+x-7)/3(x+1)

= (2x^2 + x-7)/3x+ 3

Answer:

Ratio of flour to chocolate = 6 : 4

= 3 : 2

Step-by-step explanation:

Original recipe

Flour = 3 cups

Chocolate = 2 cups

Ratio of flour to chocolate = 3 : 2

To double the original recipe

Flour = 3 cups × 2

Chocolate = 2 cups × 2

Flour = 6 cups

Chocolate = 4 cups

Ratio of flour to chocolate = 6 : 4

= 3 : 2

Answer:

y=ax+1

Answer:

Area of triangle B is 112 cm²

Option A is correct option.

Step-by-step explanation:

The dimensions of triangle B are twice the dimensions of triangle A.

Area of triangle A = 28 cm²

We need to find area of triangle B

We know that if base = b and height = h for triangle A

The area of triangle A will be: [tex]Area_A=\frac{1}{2}\times b \times h[/tex]

The dimensions for triangle B will be:

[tex]h_B = 2 h_A\\b_B = 2 b_A[/tex]

Putting in formula we get:

[tex]Area_B=\frac{1}{2}\times b\times h \\Area_B=\frac{1}{2}\times (2b)\times 2(h)\\Area_B=4( \frac{1}{2}\times b\times h)\\Area_B=4(Area_A)[/tex]

SO, we get [tex]Area_B=4(Area_A)\\[/tex]

We have Area_A = 28 cm²

Area of triangle B Area _B is:

[tex]Area_B=4(28)\\Area_B=112\:cm^2[/tex]

So, Area of triangle B is 112 cm²

Option A is correct option.

Answer:

$8.50

Step-by-step explanation:

take 22.10 divide it by 2.6 and you will get your answer.

Hope this helps

Answer:

= − 1 9

Step-by-step explanation:

Answer: Sometimes

Step-by-step explanation:

This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

Answer:

yes c is your answer look it once

Answer:

25%

Step-by-step explanation:

Since there are two coins, it's 50%, and since there are two sides to choose from, that would mean 25%. There's a 25% chance either will lie on heads, tails, or both heads or both tails.

Answer:

25%

Step-by-step explanation: because one coin landing on heads is 50%, but since there are two coins you cut 50% in half

Answer:

-3/5

Step-by-step explanation:

Let's go from the point (5, 8) to the point (10, 5).  We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3.  Thus, the slope of the line connecting these two points is m = rise/run = -3/5.

Both of these lines have the slope -3/5, given that they are parallel lines.

Answer:

Yes, it's multiplied/divided by 3. I Don't know  what a SS AA SAS is.

Step-by-step explanation:

Answer: $1,200

Step-by-step explanation:

Since multiplying 25% would take off 25% from 300, do the opposite (aka divide .25 from 300).

300/.25 = 1,200

Answer

the answer would be

D(5,-2).

Answer:

D(-6, 1)

Step-by-step explanation:

To determine the solution we can start by calculating the slope of AB;

A(-1, 4), B(2, -5)

m = -5 - 4 / 2 - (-1) = -9 / 3  = -3

Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that  is the correct option.

Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;

C(3, 4), D(-6, 1)

m = 1 - 4/- 6 - 3  = -3/-9 = 1/3rd

Correct, as you can see

So your solution is option c

Given:

One linear function represented by the table.

Another linear function represented by the graph.

To find:

The greater unit rate and greater y-intercept.

Solution:

Formula for slope (unit rate):

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given table it is clear that the linear function passes through (0,5) and (5,15). The function intersect the y-axis at (0,15), so the y-intercept is 15.

[tex]m_1=\dfrac{15-5}{5-0}[/tex]

[tex]m_1=\dfrac{10}{5}[/tex]

[tex]m_1=2[/tex]

So, the unit rate of first function is 2.

From the given graph it is clear that the linear function passes through (0,6) and (-4,0). The function intersect the y-axis at (0,6), so the y-intercept is 6.

[tex]m_2=\dfrac{0-6}{-4-0}[/tex]

[tex]m_2=\dfrac{-6}{-4}[/tex]

[tex]m_2=\dfrac{3}{2}[/tex]

So, the unit rate of first function is [tex]\dfrac{3}{2}[/tex].

Now,

[tex]2>\dfrac{3}{2}[/tex]

[tex]m_1>m_2[/tex]

And,

[tex]15>6[/tex]

Therefore, the greater unit rate of the two functions is 2. The greater y-intercept of the two functions is 15.

Answer:

The greater unit rate of the two functions is 2.

The greater y-intercept of the two functions is 6.

Step-by-step explanation:

yay!

Answer:

x = 0, y= -16

Step-by-step explanation:

Okay, we can use elimination to do this. Add the two equations together to get rid of one of the variables. 7x and -7x cancel each other out, so we are left with y+y= -32. If y+y is -32, then y= -16. Let's plug that back one of the equations. I'll choose the first equation. 7x +(-16) = -16. We can simplify that to 7x - 16= -16. Okay, we add 16 to both sides which gets us 7x=0. From this, we can infer that x=0 because 0x7=0. Now we have the answer, x=0, and y= -16. I hope this helps!
