The equation of line that has a slope of 1/2 and goes through (4,-1) is y=-3.

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

y = mx + c

where m denotes the line's slope and c is the y-intercept.

In the question, we have been given the slope and the (x,y) through which it passes.

Substituting these in y = mx + c, we get

-1= 0.5(4)+c

-1= 2+c

-3=c

c=-3.

Hence, the equation of line is y=-3.

On solving the provided question, we can say that angles MOP + NOP = MON; x = 140/4 = 35 and MOP = NOP = 2(35) +1 = 71

An angle is a form in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a point in the middle known as the angle's vertex. In the plane where the rays are placed, two rays can produce an angle. An angle is also produced when two planes intersect. They're known as dihedral angles. In plane geometry, an angle is the form that two rays or lines with a common termination might take. The Latin word "angulus," which means "horn," is where the English word "angle" comes from. The two rays, also known as the sides of the angle, have a common termination known as the vertex.

here, angles

MON = 142°, m MOP= 2x+1, and  NOP = 2x+1

so, MOP + NOP = MON

2x+1 + 2x + 1 = 142

We were informed that an is a matrix with numerous elements in this query. A is an order matrix, and we also have  an order matrix.

3 by 3, resulting in a determinant of b that is -5. We were successful in locating a matrix c that is equal to minus three times of a b cube times a.

We must determine the determinant because an is equivalent to a transport and an is equal to an identity matrix. If I take into account the period of a transposition, what is the determinant of a so-called determinant of this identity, which is equal to 1 accurate and we are aware of this characteristic.

This will be the result of those who are in a situation where a transposition is crucial. This is the first result is that the cube's time has the same determinant as a matrix's time.

Because a 3 by 3 matrix and lambda are real numbers, we can leverage this property. Using this property, it will be -3 q in this case. Once more, I'll be able to obtain a transposition b times c times a determinant. Splitting it is a possibility. The times of the b cube determinant are determined by minus 3 c. We know that the determinants of a transpose and the determinant of a that is 1 are, so what we are obtaining is just minus 27.

We shall obtain the b cube's determinant from this location. This is only multiplied by 1 minus 27. There won't be an entire cube. The determinant of c is equal to 3125, which is the product of -27 and -125.

The equations that represent the circle are x² + (y - 3)² = 36 and x² + (y + 8)² = 36.

A circle is a two dimensional figure which consist of all the points which are at equal distance from a fixed point called center of the circle.

Standard equation of a circle is,

(x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius.

Given that,

Diameter = 12

Radius = Half of diameter = 6

Center lies on the y axis.

So the coordinates of center (h, k) will be of the form (0, k).

So the equation will be of the form,

(x - 0)² + (y - k)² = 6² or x² + (y - k)² = 36

The equations of this form in options are,

x² + (y - 3)² = 36 and

The probability that all the balls are green when we randomly select them is:

P = 0.044

We know that a bag contains 4 white, 5 red and 6 green balls, then there are a total of:

4 + 5 + 6 = 15 balls.

The probability of getting a green one is given by the quotient between the number of green balls and the total number of balls, so for the first one we have:

p = 6/15

Now for the next ball, because we already took one, now there are 5 green balls and 14 in total, so the probability is:

q = 5/14

The probability for the last one is calculated in a similar way, we will get:

z = 4/13

The joint probability (the probability of getting the 3 green balls in a row) is given by the product of the probabilities above, here we will get:

If 3/4 cup of chai tea latte concentrate is 60 calories, we can use proportion to find out how many calories 1/2 cup of chai tea latte concentrate is.

What does a math ratio mean?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could athe ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.

We know that:

(3/4 cup) = 60 calories

To find out the number of calories in 1/2 cup, we can set up a proportion using the information we have:

(1/2 cup) / x = (3/4 cup) / 60

we can cross-multiply to get:

x = (1/2 cup) * (60 / (3/4 cup))

then we can simplify

x= (1/2)*(4/3)*60

x= 80/3

Therefore, 1/2 cup of chai tea latte concentrate is 80/3 calories.

The expression at the right side of the equality represents the entire expression after the least common factor is applied at the left side.

The least common side of the denominators is given as follows:

Hence the simplified numerator is given as follows:

(2x + 1)(4x + 7) + (-3x + 2)(x - 3).

Expanding the operations, and combining the like terms, we have that:
