Which equation represents a line that passes through the two points in the
table?

Answer:

Step-by-step explanation:

For there to be no solution, the graphs must never intersect.

An equation is formed of two equal expressions. The graphs that indicate that the equation has no solution are the first graph from the top row and the last graph from the second row.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of a pair of equations is the point at which the graph of the two functions intersects each other. The number of times the two graphs intersect is the number of solutions to the pair of equations.

Since there are only two graphs where the graphs do not intersect.

Thus, the graphs that indicate that the equation has no solution are the first graph from the top row and the last graph from the second row.

Graph fourth shows a system of equations with a solution at (2, -1) option fourth is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is

Which graph shows a system of equations with a solution at (2,-1)?

The graph is in the picture, please refer to the attached picture.

As we can see in the graph there are two graphs of a function shown.

The first one is a parabola and the second one is a linear graph.

From the graph, the intersection point of the two groups is at (2, -1)

The intersection point is shown in graph fourth.

Answer:

Graph 4

Step-by-step explanation:

The correct classification of the expression 5x + 3x⁴ - 7x³ + 10, is that it is the fourth-degree polynomial.

The degree of a polynomial is the highest power of the variable in the expression.

In the expression 5x + 3x⁴ - 7x³ + 10, there are 4 terms, and the term 3x⁴ involves the highest power = 4.

Therefore, the degree of the polynomial is 4.

Hence, we can say that the correct classification of the expression 5x + 3x⁴ - 7x³ + 10, is that it is the fourth-degree polynomial.

The equation of the perpendicular line as required is; y = 2x -3.

Since the line in discuss is perpendicular to the given line whose slope is; -1/2. It therefore follows that the slope of the line to be determined is;

m = -1/(-1/2) = 2.

The equation of the required line can therefore be written as;

2 = (y-7)/(x-2)

2x -4 = y -7

Hence, y = 2x -3 is the equation of the line.

Answer: x = 80°

Step-by-step explanation:

Hi,

Since the angle is bisected, that means it is split in half and that both sides equal each other.
Therefore,

50 = 1/2x + 10

subtract 10 from both sides

40 = 1/2x

divide 40 by 1/2

x = 80°

Answer:

81/4

Step-by-step explanation:

By the Pythagorean theorem, the length of the altitude drawn from the hypotenuse is

[tex] \sqrt{65} [/tex]

This means that by the geometric mean theorem, that out of the two segments the hypotenuse is split into, the one with unknown length has length 65/4.

Thus, x = 65/4 + 4 = 81/4.

For the triangle ABC, if B or C is an obtuse angle, then a = b cos C + c cos B  according to the law of sines and the addition formula.

For a triangle ABC with angles ∠A, ∠B, and ∠C and with sides a, b, and c

Thus, we can write,

sinA/a = sinB/b = sinC/c

or

a/sinA = b/sinB = c/sinC

It is given that in a ΔABC,

The ∠B or ∠C is an obtuse angle.

So, ∠A = 180° - (B + C)

⇒ sin A = sin (180° - (B + C))

⇒ sin A = sin (B + C) (since we know that sin(180° - θ) = sinθ)

From the addition formula,

sin (B + C) = sin B cos C + sin C cos B

⇒ sin A = sin (B + C)

⇒ sin A = sin B cos C + sin C cos B

From the law of sines,

a/sinA = b/sinB = c/sinC = K

⇒ aK =sin A, bK = sin B, cK = sin C

On substituting,

⇒ sin A = sin B cos C + sin C cos B

⇒ aK = bK cos C + cK cos B

⇒ K(a) = K(b cos C + c cos B)

∴ a = b cos C + c cos B

Hence it is proved.

AB = AC, they are equivalent. Since an isosceles triangle has the congruent angle property, mB = mC cannot be shown until AB=AC.

Generally, Isosceles triangles are those that have two sides that are equal in length and two angles that are also equal in size.

Hence The sides and angles theorem for triangles., and the side AB is equal to the other side AC,

In conclusion, Assuming that the base angles, mB, and mC, are of equal measure, the triangle sides and angles theorem states that segment AC is larger than AB. The bigger angle of a triangle is always opposite to the longer side, according to the theorem.

AB is congruent to AC cannot be proven unless AB=AC then,

The percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.

The standard deviation of a data set is defined as how the data is dispersed in relation to the mean.

From the question,

The raw time given (X) = 14.4 sec

The mean value(m) = 18sec

The standard deviation(d) = 1.2 sec

Using the formula,

z = X - m/ d

z= 14.4- 18/1.2

z = -3.6/1.2

z= -3

Using a Z table to find the percentage equivalent of P(x<14.4) is 0.0013499 which is approximately = 0.15%.

Therefore, the percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.
