On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3). Which point could be on the line that is perpendicular to Line M N and passes through point K? (0, −12) (2, 2) (4, 8) (5, 13)

Answers

MN goes through

(2,3)(-3,2)

Slope:-

m=2-3/-3-2=-1/-5=1/5

Slope of perpendicular line:-

-5

Passes through k(3,-3)

Equation in point slope form

y-y1=m(x-x1)y+3=-5(x-3)y+3=-5x+15y=-5x+12

Check one by one

0=-5(-12)+12=60+12=722=-5(2)+12=-10+12=2

Yes option B is correct

Answer:

(2, 2)

Step-by-step explanation:

First find the slope of the line MN, using the two given points:

[tex]\sf let\:(x_1,y_1)=(2,3)[/tex]

[tex]\sf let\:(x_2,y_2)=(-3,2)[/tex]

[tex]\implies \sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-3}{-3-2}=\dfrac15[/tex]

If two lines are perpendicular to each other, the product of their slopes will be -1.

Therefore, the slope (m) of the line perpendicular to MN is:

[tex]\implies \dfrac15 \times m=-1[/tex]

[tex]\implies m=-5[/tex]

Using the point-slope form of the linear equation with point K (3, -3), we can construct the linear equation of the line perpendicular to MN:

[tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-(-3)=-5(x-3)[/tex]

[tex]\implies \sf y=-5x+12[/tex]

Now we have the equation of the line perpendicular to MN, we can input the x-values of the solution options to see which once is correct:

[tex]x=0\implies \sf y=-5(0)+12=12\implies (0,12)[/tex]

[tex]x=2\implies \sf y=-5(2)+12=2\implies (2,2)[/tex]

[tex]x=4\implies \sf y=-5(4)+12=12\implies (4,-8)[/tex]

[tex]x=5\implies \sf y=-5(5)+12=-13\implies (5,-13)[/tex]

Therefore, the point that is on the line that is perpendicular to MN and passes through point K is (2, 2)

what two numbers that can multiply into 60 and add into 19

Answers

Answer:

15 and 4

Step-by-step explanation:

we must first find the Factors:

1,    2,    3,   4,    5

60, 30, 20,  15,  12

Now we can add them to find what adds to 19

1+60 = 61

2+30 = 32

3+20 = 23

4+15 = 19

The two numbers are 4 and 15 because 4x15=60 and 4+15=19.

expand and simplify 2(3a-5b +4 (a+2b)

Answers

Answer:

14a + 6b

Step-by-step explanation:

To expand use distributive property. a*(b +c) =a*b +a *c

Simplifying an expression

2*(3a - 5b + 4*(a+2b) = 2*(3a -5b + 4*a +4*2b)

                                  = 2*(3a - 5b + 4a + 8b)

                                  = 2* (3a + 4a - 5b + 8b)

Combine like terms.  To combine like terms, add or subtract the coefficient of the variables. 3a and 4a   & (-5b) and 8b are like terms  

                                 = 2*( 7a + 3b)  

                                 = 2*7a + 2*3b

                                 = 14a + 6b

Hey there!


2(3a - 5b) + 4(a + 2b)

= 2(3a - 5b) + 4(1a + 2b)

= 2(3a) + 2(-5b) + 4(1a) + 4(2b)

= 6a - 10b + 4a + 8b

= (6a + 4a) - (10b + 8b)

= 6a + 4a - 10b + 8b

= 10a - 2b


Therefore, your answer is: 10a - 2b

Fleur has 32 collectable playing cards. 3/8 of the playing cards are red. 2/8 of the playing cards are blue. The rest were green. How many of the playing cards were green? Explain how you found your answer.

Answers

3/8 of 32 would be 12, and 2/8 of 32 would be 8. Because these fractions are different colors, you could add them to get 20, then subtract 32 - 20 to get 12. Therefore, 12 of the cards were green (or 3/8). You could also find the answer by thinking of it in terms of fractions only; 3/8 + 2/8 = 5/8, which means the other 3/8 adds up to 32 cards. As mentioned above, 3/8 of 32 is 12, so again, 12 playing cards were green. Hope this was helpful and understandable for you!

find the value of x from the square​

Answers

Answer:

X = 5

Step-by-step explanation:

From the given figure,

one length of a square(l)= x

Area of the square(A) = 25cm^2

We know,

Area of square(A)= l^2

or, 25=x^2

or, √25 = x

or, 5cm = x

x = 5

Step-by-step explanation:

Side = x cm

Given, that the area of the square = 25cm^2

therefore,

area of square = (side)^2

25 = x^2

x = √25

x = 5 cm.

What is the vertex?
(X= -b/2a)

What is the Y intercept?

Answers

Step-by-step explanation:

any quadratic equation has the form

y = ax² + bx + c

so, we can see in our case

a = 1

b = 8

c = 7

the x value of the vertex is indeed camcorders by

x = -b/(2a) = -8/2 = -4

the corresponding y we get then

y = (-4)² + 8×-4 + 7 = 16 - 32 + 7 = -9

the vertex = (-4, -9).

the y- intercept is simply the point with x = 0 (and the corresponding y value).

which is c, because

y = 0² + 8×0 + 7 = 7

the y-intercept = (0, 7)

Which polynomials are prime? check all of the boxes that apply. x2 9 x2 – 9 x2 3x 9 –2x2 8

Answers

Prime polynomials cannot be factorized in smaller degree polynomials. The prime polynomials out of the considered option are:

Option 1: x^2 + 9Option 3: x^2 + 3x + 9

What are prime polynomials?

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

Checking all the options for them being prime or not:

Option 1: [tex]x^2 + 9[/tex]

Take [tex](x+a)(x+b) = x^2 + 9[/tex]

Then, expanding it gives:

[tex]x^2 + (a+b)x + ab = x^2 + 9 \implies a+b = 0, ab = 9[/tex]

or we get: [tex]a = -b, ab = -b^2 = 9, b^2 = -9[/tex]

Square of a real number doesn't exist, so this factor doesn't exist. Thus, it is prime polynomial.

Option 2: [tex]x^2 - 9[/tex]

We have the identity [tex](a+b)(a-b) = a^2 - b^2[/tex]

and since 9 is square of 3, therefore, we get:

[tex]x^2 -9 = x^2 -3^2 = (x+3)(x-3)[/tex]

So it got factorized. Thus, not a prime polynomial.

Option 3:  [tex]x^2 +3x + 9[/tex]

Take [tex](x+a)(x+b) = x^2 + 3x + 9[/tex]

Then, expanding it gives:

[tex]x^2 + (a+b)x + ab = x^2 + 3x + 9 \implies a+b = 3, ab = 9[/tex]

That gives:

[tex]a = 3-b\\ab = b(3-b) = 3b - b^2 = 9\\b^2 -3b + 9 = 0[/tex]

Solving this quadratic equation by root formula gives:

[tex]b = \dfrac{-(-3) \pm \sqrt{(-3)^2 -4(1)(9)} }{2}\\\\b = \dfrac{-(-3) \pm \sqrt{-27} }{2}\\[/tex]

this makes 'b' a complex number and it doesn't remain a real number as its expression contains square root of a negative number.

Thus, this polynomial cannot be factorized in terms of smaller degree polynomials. Thus, its a prime polynomial.

Option 4: [tex]-2x^2 + 8[/tex]

Taking -2 common out, we get:

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

Thus, it got factorized, and therefore not a prime polynomial.

Thus, the prime polynomials out of the considered option are:

Option 1: [tex]x^2 + 9[/tex]Option 3: [tex]x^2 + 3x + 9[/tex]

Workout a b and c

Answers

Answer:

a=21° b=70°

Step-by-step explanation:

a=21°(Vertically Opposite Angles)

b+110°=180° (linear pair)

b=180-110

b=70°

[please mark me brainliest]

Answer:

a = 21°

b = 70°

c = 89°

Step-by-step explanation:

angle of measure b and the angle of measure 110 are two supplementary angles

Then b + 110 = 180

Therefore b = 180 - 110 = 70°

angle of measure b and the angle of measure 21 are two opposite angles

Then a = 21

We Know that the sum of the interior angles of a triangle equal to 180

Then a + b + c = 180

Therefore c = 180 - a - b = 180 - 21 - 70 = 159 - 70 = 89°

Answers

The area of the circle that contains the sector is 546.5 in² (rounded to the nearest tenth)

Calculating area of a circle

From the question, we are to determine the area of the circle.

The area of a circle can be determined by using the formula,

[tex]A = \pi r^{2}[/tex]

From the given information,

Area of the sector = 167 in²

Arc measure = 110°

Using the formula,

[tex]Area\ of\ sector = \frac{\theta}{360 ^\circ} \times \pi r^{2}[/tex]

Then,

[tex]167= \frac{110 ^\circ}{360 ^\circ} \times \pi r^{2}[/tex]

[tex]167= \frac{11}{36} \times \pi r^{2}[/tex]

[tex]\pi r^{2} =\frac{167 \times 36}{11}[/tex]

[tex]\pi r^{2} = 546.5 \ in^{2}[/tex]

Since area of the circle, A, is given by πr²

The probability that she will take jazz on wednesday night is 27%. If the probability that she will take ballet is 70%, what is the probability that she will take jazz on saturday morning?.

Answers

The probability that Juliana will take jazz on Saturday morning based on the decision tree given is 3%.

What is the probability that jazz is taken on Saturday morning?

The probability that jazz is taken is:

= 1 - Probability of ballet

= 1 - 70%

= 30%

The probability that if jazz is taken, it will be taken on Wednesday is:

= Probability that jazz is taken on Wednesday night / Probability that Jazz is taken

= 27% / 30%

= 90%

The probability that Jazz is taken on Saturday morning is therefore:

= Probability that jazz is taken x (1 - Probability of Wednesday night)

= 0.3 x ( 1 - 90%)
