Answer:

B

Step-by-step explanation:

A is false. 0 + 1 - 2 = -1, not 0.

B is true.

(-2)-(-2) +0

= -2 + 2 + 0

= 0

C is false, since B is true.

Equation B 0=(-2)-(-2) +0 is true, which is simplified by subtraction.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

For equation A:

0 = 0+1-2

We can simplify the right-hand side of the equation by combining like terms:

0 = -1

This is not true, so we might be tempted to say that equation A is false.

For equation B:

0 = (-2)-(-2) + 0

We can simplify the right-hand side of the equation by performing the subtraction:

0 = 0 + 0 + 0

This simplifies to:

0 = 0

This equation is true.

Therefore, equation B is true.

Triangles will only be right triangles if a² + b² = c² where a and b are legs and c is hypotenuse. Numbers 1 and 2 pass this test so the answer is c.

Answer:

C. I and IV only

Step-by-step explanation:

Apply the Pythagorean theorem to all triangles, and see which ones make the equation true.

I.

8^2 + 15^2 = 64 + 225 = 289

17^2 = 289

289 = 289

II.

4^2 + 5^2 = 16 + 25 = 41

6^2 = 36

41 is not equal to 36

Not a Right Triangle

III.

2^2 + 2^2 = 4 + 4 = 8

3^2 = 9

8 is not equal to 9

Step-by-step explanation:

3x-4y=6

-4y=-3x+6

y=(3/4)x-(3/2)

positive slope with y-intercept at -3/2 corresponds to D

Graph includes the points (0,-3/2) and (2,0). Therefore, option D is the correct answer.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

The given linear equation is 3x-4y=6

Graph the line using the slope and y-intercept, or two points.

Slope: 3/4

y-intercept:

(0,-3/2)

Plot the points (0,-3/2) and (2,0)

Step-by-step explanation:

all you have to do for this question is to plug the values for a, b, and c in the question.

ab + c  would be

(-3)*4+(-5)

-12+(-5)

= -17

therefore the answer is -17

Answer:

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).

Answer:

x=10.93 or 10.9

Step-by-step explanation:

To find x we use sin

sin(40) = 0.6427876097  then * 17

= 10.9273

= 11

We can check and plug in answer as inverse to find other side

11/sin (40degree) x (90 degree) = 17.11

If we plug in the original 10.9273 we actually find 17

So we should show the correct amount 10.9273 and if rounding try 10.93

10.93/sin (40 degree) x sin (90 degree) = 17.00

Answer:

the weight for an object with a velocity of 12 meters per second is 600 kilograms

Step-by-step explanation:

The linear momentum of an article is : p = mv

Where p = Momentum

m = mass

v = velocity

The velocity is 16 meters per second and the object weighs 450 kilograms

So, [tex]p = 450 \times 16[/tex]

We are supposed to find the weight for an object with a velocity of 12 meters per second

So, p = 12m

We are given that the linear momentum is a constant when the mass varies inversely of the velocity.

So, [tex]450 \times 16 = 12 \times m\\\frac{450 \times 16}{12}=m\\600=m[/tex]

Hence the weight for an object with a velocity of 12 meters per second is 600 kilograms
