Answer:

6

Step-by-step explanation:

2y/3 + 1/3 = y/2 + 1/6

We want to eliminate the fractions

The least common multiple of 3,2 and 6 is 6

Multiply each side by 6 to get rid of the fractions

6(2y/3 + 1/3) = 6(y/2 + 1/6)

4y +2 = 3y +1

Answer:

a= -3, b= 4 and c= -5

ab + c = (-3)4+(-5) = -12 -5 = -17

Answer:

answer is -17

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:

A. y=-3x+4

Step-by-step explanation:

Since the equation is in y=mx+b form, m represents the slope of a line. To solve for slope-intercept, use the equation m=(y2-x2)/(y1-x1).

[tex]m=\frac{-2-4}{2-0}[/tex]

[tex]m=\frac{-6}{2}[/tex]

[tex]m=-3[/tex]

Make sure to plug in one of the points into the equation to check if the numbers equal to one another or not.

Answer:

Slope: -1

y-intercept: 0

The graph of the function y = - x is attached at the end of the answer.

        [y] = ax + b

        It has a degree of one and has only one root.

Given is the function as -

y = f(x) = - x

We have the following function -

y = - x

The function y = -x is a linear function. Refer to the graph of the function attached. The function has a slope of -1 .

Therefore, the graph of the function y = -x is attached with the answer.

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

Right Triangle

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

Not a Right Triangle

IV.

9^2 + 12^2 = 81 + 144 = 225

15^2 = 225

225 = 225

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

Answer:

P(A and B)= p(A) * P(B)

Step-by-step explanation:

The Formula for the probability of A and B (independent events) is

p(A and B) = p(A) * p(B).

Answer:

As you may know, the addition of all the interior angles of a triangle always adds up to 180°.

So if we know two angles of the triangle, A1, and A2, we can find the third angle as:

A1 + A2 + X = 180°

X = 180° - A1 - A2.

Se with only knowing two angles, we can find the third angle.

So aaa is a criteria equivalent to aa.

Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.

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).

the answer is 15!

The square root of the number -√75 will be -3√5.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The square root of the number will be calculated as below:-

-√75 = - √( 3 x 3 x 5 )

        = -3√5

Therefore, the square root of the number -√75 will be -3√5.

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.
