The product of two negative rational numbers is _____ zero.
never

always
(I think I know the answer but I'm not confident)

Answers

Answer:

always

Step-by-step explanation:

Answer:

ALWAYS

Explain:

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.

Problem: Four students tried to write 12x + 3y=9 in equivalent y= mx + b form.
Question: Did each student get an equation that is equivalent to the original Ax + By=C form?
If so, explain the reasoning for each step. If not, tell what errors the students made.

Answers

if you convert it to y=mx+b then you would have to subtract 12x from each side to make it 3y= -12x + 9 which if u divide by 3 is y=-4x + 3

Answer:

If they got y = -4x + 3 it is equivalent to the original.

Step-by-step explanation:

Common errors include leaving the y with a coefficient, forgetting to simplify all the terms or getting the slope wrong by using the opposite sign.

When two or more quantities have the same exponents, their bases can be multiplied together.

Because 6 x 6 x 6 is 216 and 7 x 7 x 7 is 343 if you multiply those two umbers together you will get the same answer as 42 x 42 x 42 which is 74,088

Answers

Answer:

66

Step-by-step explanation:

Both bottom angles are equal

So x+x+48=180

Subtract 48 from both sides

So 2x=132

Divide both sides by 2

x=66

You can tell that this triangle is an isosceles triangle as both sides are the same length. In an isosceles triangle, the bottom two angles are always equal. The angles in a triangle always add to 180 degrees. You are given the fact that the top angle is 48 degrees. If you do 180 - 48, that will give you 132 degrees, which is the sum of the bottom two angles. If you divide that by 2, you will get 66 degrees, which is one of the angles.

Therefore, x = 66 degrees.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

the difference between solving for surface area and solving for volume

Answers

Answer: The Surface Area is a sum total of Area of the planes that form a surface/shape while Volume is the space enclosed within a figure/shape/surface.

The Surface Area is a 2-Dimensional concept with units m², cm² or mm² where as Volume is a 3-Dimensional concept with m³, cm³ or mm³ as units.

Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

i know the anwser is two but how do you get it

Answers

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0

To solve this problem, we need to simplify each expression and see which one, when added to | −5 + 7 |, will equal zero.

We start by simplifying | −5 + 7 |:

| −5 + 7 | = | 2 | = 2

Now we can simplify each of the answer choices:

[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2

We see that only choice [2], when added to | −5 + 7 |, will equal zero:

2 + (−2) = 0

Therefore, the answer is [2] | +5 − 7 |.

i honestly have no clue i just need to answer a question do i can ask my question that i needed help with,

Forty-five students were surveyed about what their favorite sport is. Ten said Hockey was their favorite. There are 414 students total. Based on this, estimate how many of the 414 students would favor Hockey?

Answers

To estimate how many of the 414 students would favor Hockey, we can use proportion. We know that 10 out of 45 students favor Hockey, so we can set up a proportion:

10/45 = x/414

where x is the estimated number of students who favor Hockey out of the total 414 students.

To solve for x, we can cross-multiply:

10 * 414 = 45 * x

4,140 = 45x

x ≈ 92

Therefore, we can estimate that around 92 out of the 414 students would favor Hockey.
