Little tip my teacher taught me in 5th or 6th grade ,look at which way the arrow is pointing and compare it to an inequality symbol (imagine the inequality symbol as the arrow).

In this case the arrow is pointing right , so which inequality symbol looks most like it?

Obviouslyy,the less than sign!

Also! , an closed circle means "or equal to" which is the line under the inequality symbol.

And an open circle basically means just the inequality symbol.

oi can someone help me with this one ^{2}-12x-28=0
This is still pretty confusing for me

Answers

Answer:

Both answers should be -2 and 14.

Step-by-step explanation:

Using the quadratic formula:

[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]

Therefore:

[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

What is an equation of the line that passes through the points (-6, 2) and (6, –2)?

Answers

Answer:

y=(-1/3)x

Step-by-step explanation:

y=mx+b

(x,y)

put in the first point into y=mx+b

2=m(-6)+b

then the second point is (6,-2)

put the point into y=mx+b

-2=6m+b

----------------------------

Put both equations in a system of equations

-2=6m+b

2=m(-6)+b

solve for m and b

-1/3=m and 0=b

so put that back into y=mx+b

y=(-1/3)x+0

so that is the only line that passes through both points

Which shape shows the cross-section of the square pyramid when it is cut by a plane parallel to the base?

Answers

Answer:

Triangle

Step-by-step explanation:

A pyramid is a strong-solid shape that is comprised of triangles, square shapes, squares, and different polygons. Pyramids are arranged depending on the state of their base. For instance, the outline given is a square-based pyramid in light of the state of its base(which is a square). Different sorts incorporate the three-sided based pyramid, three-sided based pyramid, and other polygon-based pyramids.

In the event that this square pyramid is cut with a plane that is corresponding to the base of the pyramid, the state of its cross-area will be a triangle since the shapes that are corresponding to the base are altogether triangles. So slicing the plane corresponding to the base is like removing one side of the triangle making up the pyramid.

A bag contains 24 discs.
8 are red and 16 are blue.
One disc is taken out at random and replaced by two of the other colour.
Another disc is then taken out at random and replaced by two of the other colour.
Another disk is taken out at random
Work out the probability that all three discs are taken out red

Answers

Answer:

Step-by-step explanation:

8/24 are Red

Pick and return 2

So it will be 7/25

Again pick and return 2

Then it is 6/26

Now multiply the results

8/24 × 7/25 × 6/26 = 7/ 325

The probability that all three discs are taken out of red will be 7/ 325.

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that a bag contains 24 discs. 8 are red and 16 are blue. One disc is taken out at random and replaced by two of the other colour. Another disc is then taken out at random and replaced by two of the other colour.

The probability will be calculated as,

Red = 8/24

Pick and return 2 it will be 7/25

Again pick and return 2 then it is 6/26

Now the overall probability will be,

P = 8/24 × 7/25 × 6/26 = 7/ 325

Therefore, the probability that all three discs are taken out of red will be 7/ 325.

Write the equation of the circle.

A: (x+3)2+(y−6)2= 2

B: (x−3)2+(y+6)2= 2

C: (x+3)2+(y−6)2= 4

D: (x−3)2+(y+6)2= 4

Answers

Answer:

C. (x + 3)² + (y - 6)² = 4

Step-by-step explanation:

Get the center and radius from the graph.

Center is: (-3, 6)Radius is: 2

Use the circle formula:

(x - h)² + (y - k)² = r²

We have:

h = -3, k = 6, r = 2

Substitute and get the equation:

(x - (-3))² + (y - 6)² = 2² ⇒(x + 3)² + (y - 6)² = 4

Correct choice is C

Step-by-step explanation:

So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)

If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!

Answers

Answer:

Faye's probability of pulling out a white marble is 3/80.

Step-by-step explanation:

To find the probability, we must first add everything up. 10 + 13 + 16 + 10 + 11 = 60 marbles. Now we divide 60 by the amount of white marbles there are. 60 ÷ 16 = 3.75% or 3/80. Therefore, the probability of Faye pulling out a white marble is 3/80.
