Find the value
of 6y^2 - 24y - 51 when y=-2

Answers

Answer:

Step-by-step explanation:

6(y^2) - 24y -51 = 6 4 - 24y - 51

(6 4) - (24y) - 51 = 24 - -48 - 51

(24 - -48) - 51 = 72 - 51

72 - 51 = 21

Therefore, both equations are equal.

Plz, help I have no clue how to solve this.

Answers

Answer: Create equations. Top length=Bottom length

Left side = right side.

Combine like terms and rewrite the equations.

Use the new equations to create a system of equations to solve for x and y.

Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.

You should end up with top and bottom lengths of 10. The sides are 9.

Step-by-step explanation:

3x-5 = 18 -2y . Rewrite as 3x + 2y = 23

x+4 = 21 -3y Rewrite as x + 3y = 17

The system of equations is

3x + 2y = 23 and x + 3y = 17 . To solve by substitution, multiply the second equation by -3 It becomes -3x-9y= -51 Add the equations so the x terms cancel. Solve for y

3x + 2y = 23

-3x - 9y = -51

0 -7y = - 28 Divide both sides by -7. y = 4

Substitute 4 for y, solve for x

x + 3(4) = 17

x + 12 = 17 . Subtract 12 from both sides x = 5

Substitute the values of x and y in the expressions

Top: 3x-5 is 3(5) -5 becomes 10

Bottom: 18 -2y is 18 - 2(4) becomes 10

Left: x +4 is (5) + 4 becomes 9

Right: 21 - 3y is 12 -3(4) becomes 9

Can someone please explain why x= -2! ASAP!!

Answers

Because you add both negative x’s which is -2 and add the -6 in the right side so then it’s -2x=4
Divide and you get x=-2

9514 1404 393

Answer:

x = -2 because that is the value that makes the equation true

Step-by-step explanation:

Minus signs are everywhere. They can all be eliminated by multiplying both sides of the equation by -1.

-1(-x -6 -x) = -1(-2)

(-1)(-x) +(-1)(-6) +(-1)(-x) = 2 . . . . . distribute the -1

x + 6 + x = 2 . . . . . . . . simplify

x + x + 6 = 2 . . . . . . . . rearrange

(1 +1)x +6 = 2 . . . . . . . . factor, using the distributive property

2x +6 = 2 . . . . . . . . . . . simplify

2x +6 -6 = 2 -6 . . . . . . subtract 6 from both sides

2x = -4 . . . . . . . . . . . . . simplify

(2x)/2 = (-4)/2 . . . . . . . divide both sides by 2

x = -2 . . . . . . . . . . . . . . simplify

x is -2 because that is the value we get when we apply the properties of equality to the equation. We can check to see if it works in the original equation.

Check

-x -6 -x = -2

-(-2) -6 -(-2) = -2 . . . . put -2 where x is

2 -6 +2 = -2 . . . . . . . . simplify the signs

-4 +2 = -2 . . . . . . . . . . add the first two terms (could do all at once)

-2 = -2 . . . . . . . . yes, the value of x=-2 makes the equation true

Additional comment

The properties of equality we're concerned with here are the multiplication property of equality, the addition property of equality and the division property of equality. Respectively, these tell us that multiplying, adding, or dividing both sides of the equation by the same number doesn't change the value of the variable.

These properties are essential to understanding how algebra works.

If 4 cats enter a room and 3 leave how many monkey are in the water?

Answers

Answer:

1 monkey because it ate one of the cats

Step-by-step explanation:

Answer:

3 cats in 3corners

Step-by-step explanation:

the question is incorrect the correct question is IN A SQUARE ROOM THERE ARE 4 CATS IN EVERY CORNER?

Hey there !!!!

If you read that there are 4 cats in the room and in front of each cat is another 3 cats, then it might lead you to the answer of 16. This is not correct.

You will have reached this answer if you assumed that there was 3 cats in front of every cat in the corner. That would mean 4 cats in every coner.

You can reach this answer by dissecting each statement in the riddle. The first statement, “In a square room there are 4 cats in every corner of the room,” then we know that the room is square with 4 corners and that there are 4 cats to begin with.

The second statement of the riddle reads “In front of each cat there are 3 cats.” As we already know from the first statement that there are 4 cats in the room, each cat will see the other 3 cats in the other 3 corners of the room.

Your friend says that the table represents an exponential function because y is multiplied by a constant factor. Is your friend correct? Explain.
A.Yes. Because y is multiplied by a constant factor, the function is exponential.
B.Yes. Because y increases by greater amounts as x increases, the function is exponential.
C.No; Because y is multiplied by a constant factor, the function is not exponential.
D. No; Because x increases by different amounts, the function is not exponential.
x: 0,1,3,6
y: 2,10,50,250

Answers

Answer:

C.No; Because y is multiplied by a constant factor, the function is not exponential.

Step-by-step explanation:

For a set of number to be exponential, there is need for it to show a logical increase of a given time frame when the set of number is multiplied by a constant factor. In the table given, though the Y function is multiplied by a constant factor, the increase of the function is irregular so therefore cannot be said to be exponential.
