Answer:

collinear points

Step-by-step explanation:

A line is defined by two points and is written as shown below with an arrowhead. Two lines that meet in a point are called intersecting lines. A plane extends infinitely in two dimensions.

I've labeled where the vertex is and where the parabola should be. I recommended using this online calculator called desmos. Super useful!

Answer:  It does not lie on the line m.

Step-by-step explanation:

First using the slope and the point find an equation in slope intercept form and plot in the coordinates (82,63) to see if it fits. If it fits then it lies on line m and if doesn't then it doesn't like  on line M.

The slope intercept formula is   y = mx +b   where m is the slope and b is the y-intercept, so we need to use the coordinates (-2,1) to find the y-intercept.

Plot the coordinates and the slope into the formula to solve for b.

1 = 3/4(-2) + b

 1 = -6/4 + b    

+6/4 +6/4  

  b = 10/4  

y = 3/4x + 10/4

63  = 3/4(82) + 10/4  

63 = 64

Answer:

61/50

Step-by-step explanation:

1*a = a

1 = b/b

then:

23*25 * 1 = (23/25)(12/12) = (23*12)/(25*12) =276/300

9/30 *1 = (9/30)(10/10) = (9*10)/(30*10) = 90/300

then:

(23/25) + (9/30) = (276/300) + (90/300)

= (276+90)/300

= 366/300

= 122/100

= 61/50

The addition of the fraction 23/25 + 9/30 is equal to 61/50.

A fraction represents a part of a number or any number of equal parts.

'a/b' of a quantity means that quantity is first divided in 'b' parts, and then mutiplied by 'a', or,

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

1*a = a

1 = b/b

then:

23*25 * 1 = (23/25)(12/12)

= (23*12)/(25*12) =276/300

9/30 *1 = (9/30)(10/10)

= (9*10)/(30*10) = 90/300

Now add the terms;

(23/25) + (9/30) = (276/300) + (90/300)

= (276+90)/300

= 366/300

= 122/100

= 61/50

Therefore, the addition of the fraction 23/25 + 9/30 is equal to 61/50.

Set of ordered pairs (x, y) could represent a linear function

B= {(-1,2), (2, 1), (5,0), (8, -1)}

Option B is correct

Linear function is a function whose graph is a straight line .

Slope of a line tells us how steep the line is . Slope of a line is same at all the points.

Slope formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Lets find out slope of any two points in each option

A = {(-6,3), (-3,0), (0, -3), (3,-5)}

[tex]\frac{0-3}{-3+6} =-1\\\frac{-5+3}{3-0} =-\frac{2}{3} \\[/tex]

Slopes are not same

Lets check the second option

B={(-1,2), (2, 1), (5,0), (8, -1)}

[tex]\frac{1-2}{2+1} =\frac{-1}{3} \\\frac{0-1}{5-2} =\frac{-1}{3} \\\frac{-1-0}{8-5} =\frac{-1}{3} \\[/tex]

The slope of any two points are equal .

slope are same . So it represents a linear function .

C = {(-4,-7), (-1, -3), (2.0), (5,3)}

[tex]slope =\frac{-3+7}{-1+4}=\frac{4}{3} \\slope =\frac{0+3}{2+1}=\frac{3}{3}=1[/tex]

Slopes are not same . So it is not a linear function

D = {(-5, -8), (-2,-4), (1,1), (4,6)}

[tex]slope = \frac{-4+8}{-2+5}= \frac{4}{3} \\Slope = \frac{1+4}{1+2}= \frac{5}{3} \\\\slope = \frac{6-1}{4-1}= \frac{5}{3} \\[/tex]

Slopes are not same . so it is not a linear function .

Option B is correct.

Answer:

40 DEGREES COUNTERCLOCKWISE

140 DEGREES CLOCKWISE

Step-by-step explanation:

To get from frame one to frame two you can either rotate the object in a clockwise or anticlockwise direction.

We can use the edges of the rectangle to monitor the degree with which it is rotated.

If we rotate in a clockwise direction, it means that we are rotating from the left to the right; that is in the direction of the clock. If we are turning this way, we would have to turn the rectangle through 140 degrees to get it into frame 2's position

If we are rotating in the anticlockwise direction (against the direction of the clock) we are turning it from the right to the left. We will be turning it by only 40 degrees to get it into frame 2's position

Answer:

Length of the thread = 30 metres

Step-by-step explanation:

Length of the thread in one round of a reel = Circumference of the reel

                                                                    C = [tex]2\pi r[/tex]

Since radius of the reel = [tex]\frac{\text{Diameter}}{2}[/tex]

                                       = [tex]\frac{5}{2}[/tex]

                                       = 2.5 cm

Circumference of the reel = 2(π)(2.5)

                                           = 5π

                                           = 5×3

                                           = 15 cm

Length of the thread wound in one round around the reel = 15 cm

Since, thread is wound 200 times round a reel, length of the thread

= 200 × 15                                                      

= 3000 cm

≈ 30 metres

Therefore, Option (B) will be the answer.

Answer:

25 = 5^2

Step-by-step explanation:

Factor the following integer:

25

Hint: | Is 25 divisible by 2?

25 is not divisible by 2 since 25 is odd and 2 is even:

25 = 25 (25 is not divisible by 2)

Hint: | Is 25 divisible by 3?

The sum of the digits of 25 is 2 + 5 = 7, which is not divisible by 3. This means 25 is not divisible by 3:

25 = 25 (25 is not divisible by 2 or 3)

Hint: | Is 25 divisible by 5?

The last digit of 25 is 5, which means 25 is divisible by 5:

25 = 5 5:

25 = 5×5 (5 is not divisible by 2 or 3 since 25 is not)

Hint: | Now try to factor 5. Is 5 prime?

No primes less than 5 divide into it. Therefore 5 is prime:

25 = 5×5

Hint: | Express 25 as a prime power.

There are 2 copies of 5 in the product:

Answer:

Start with the parent function y=1/x^2.

Add 3 to x in the denominator, because the graph is shifted left 3. Add 1 to the fraction, because the graph is shifted up 1 unit.

Step-by-step explanation:

When a function is transformed, it means the function is either rotated, dilated, rotated or translated.

The equation of the function whose graph is sketched is:

[tex]f(x) = \frac{1}{(x + 3)^2} + 1[/tex]

The parent function is an inverse function of the form:

[tex]y = \frac 1{x^2}[/tex]

The parent function is shifted in two ways.

When a function is shifted to the left, the rule is:

[tex](x,y) \to (x + h,y)[/tex]

Where:

[tex]h \to[/tex] number of units.

So, we have:

[tex](x,y) \to (x + 3,y)[/tex]

The function becomes

[tex]y' = \frac{1}{(x + 3)^2}[/tex]

When a function is shifted up, the rule is:

[tex](x,y) \to (x ,y+b)[/tex]

Where:

[tex]b \to[/tex] number of units.

So, we have:

[tex](x,y) \to (x ,y+1)[/tex]

The function becomes

[tex]y'' = \frac{1}{(x + 3)^2} + 1[/tex]

So, the graph of the function in the given graph (see attachment) is:

[tex]f(x) = \frac{1}{(x + 3)^2} + 1[/tex]

Answer: B. Definition of midpoint

The midpoint A cuts the line segment DW in half. So DW is cut into two pieces DA and WA, both of those smaller pieces are the same length.

Answer:

20n² - 40n + 20

Step-by-step explanation:

(5n - 5)(4n - 4)

= 5n(4n) + 5n(-4) - 5(4n) - 5(-4)

= 20n² - 20n - 20n + 20

= 20n² - 40n + 20

Another way to do this:

(5n - 5)(4n - 4)

= 5(n - 1) * 4(n - 1)

= 20(n - 1)(n - 1)

= 20(n - 1)²

= 20(n² - 2n + 1)

= 20n² - 40n + 20
