The quadratic solution of the linear system of equations y = x2 + 5x - 3 is y = (x+3)(x-1).

1. Rewrite the equation as y = x2 + 5x - 3

2. Factor the equation by grouping the terms: y = (x+3)(x-1).

3. Set each factor equal to 0 and solve for x: x+3 = 0 and x-1 = 0

4. Solve each equation: x = -3 and x = 1

5. Substitute the values of x into the original equation to find the corresponding values of y:

y = (-3+3)(-3-1) = (-3)(-4) = 12

y = (1+3)(1-1) = (4)(0) = 0

Therefore, the solution of the linear quadratic system of equations y = x2 + 5x - 3 is y = (x+3)(x-1).

Answer:

the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.

Step-by-step explanation:

To find the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6), we can first add the two given expressions to find the sum, and then subtract the third expression from that sum.

The sum of (2x^3 −3x+2) and (5x^2 +4x−6) is:

(2x^3 −3x+2) + (5x^2 +4x−6) = 2x^3 +5x^2 −3x+4x −6 = 2x^3 +5x^2 +x−6

Subtracting (3x^3 −2x^2 +6x−1) from this sum gives us:

(2x^3 +5x^2 +x−6) − (3x^3 −2x^2 +6x−1) = (2x^3 −3x^3) + (5x^2 −2x^2) + (x+6x) − (−1−6) = −x^3 +3x^2 +7x−5

Therefore, the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.

Step-by-step explanation:

⭐ What is the HL theorem?

✔️In this problem, it is already established that ΔABC and ΔADC are right triangles because they have a right angle.

✔️ΔABC and ΔADC have congruent hypotenuses because they both share hypotenuse AC, and by the reflexive property of congruence, AC ≅ AC

❌There is no indication that their corresponding legs are congruent, and that is what we need for the HL theorem.

The only answer option that mentions their corresponding legs being congruent is option C.

The product of a fraction and its reciprocal is 1

In mathematics, we know that the fraction that is obtained by swapping or interchanging the numerator and the denominator with each other is known as the Reciprocal of the given fraction.

For example, if we have the fraction 3/5, it is safe to say that the reciprocal of this fraction will be 5/3.

Now, this means that 3/5 * 5/3 = 1.

Thus, we can say that the product of a fraction and its' reciprocal is the same as 1.

The system of the equation's solution is x = -6 and y = 4 which is determined by graphically.

The system of equations is given in the question as:

y = 1/6 x + 5

4x + 3y = -12

For the first equation, y = 1/6x + 5, we can plug in two values for x and solve for y to find two points on the line. Let's plug in x = 0 and x = 1 to find two points:

When x = 0, y = 1/6(0) + 5 = 5. So the point (0, 5) lies on the line.

When x = 1, y = 1/6(1) + 5 = 5 + 1/6 = 5 1/6. So the point (1, 5 1/6) lies on the line.

For the second equation, 4x + 3y = -12,

Let's plug in y = 0 and y = 1 to find two points:

When y = 0, 4x + 3(0) = -12.

4x = -12, so x = -3. So the point (-3, 0) lies on the line.

When y = 1, 4x + 3(1) = -12.

4x + 3 = -12, so x = -4. So the point (-4, 1) lies on the line.

To solve these equations graphically, we plotted the lines on the coordinate plane, found the point of intersection, and then found the coordinates of that point.

Thus, the solution to the system of equations is x = -6 and y = 4.

The AAA (angle-angle-angle) similarity theorem can be used to express it as follows: two triangles have equal corresponding angles if and only if their corresponding sides are proportionate.

The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.

Proof:

Consider two triangles ABC and DEF, such that ∠A = ∠D, ∠B = ∠E and ∠C = ∠F as shown in the figure.

Now, cut DP= AB and DQ= AC and join PQ. Hence, we can say that a triangle ABC is congruent to the triangle DPQ.

(i.e) ∆ ABC ≅ ∆ DPQ, which gives ∠B = ∠P = ∠E and also, the line PQ is parallel to EF.

Therefore, by using the basic proportionality theorem, we can write

DP/PE = DQ/QF.

(i.e) AB/DE = AC/DF. …(1)

Similarly,

AB/DE = BC/EF …(2)

From (1) and (2), we can write:

AB/DE = BC/EF = AC/DF.

Therefore, the two triangles ABC and DEF are similar.

Hence, AAA(Angle-angle-angle) is proved.

Answer:

no solutions

Step-by-step explanation:

y = -x + 4

y=-x+1

-x+1 = -x+4  ==> since y=-x+1 and y=-x+4, -x+1=-x+4

-x+1-1 = -x+4-1  ==> isolate x on one side by subtracting 1 on both sides

-x = -x+3

-(-x) = -(-x+3)

x = x - 3  ==> this isn't equal since a number won't have the same value if

                     you take away 3 from it.

Hence, there are no solutions.

Answer:

There is no solution

Step-by-step explanation:

y = -x + 4

y=-x+1

If we solve

-x + 4 = -x +1

Add x to both sides and it will be 0

So, there is no solution!

The slope ratio for a line that makes an angle of 30 with the positive direction of the x-axis is 1:√3

The slope of a line is nothing but the change of the line in the y-coordinate concerning the change in the x-axis. So the slope is simply nothing but a ratio of change in the y-axis to change in the x-axis which is also called slope ratio.

m = change in y / change in x

tan 30= 1/√3 = change in y / change in x

tan 30= 1: √3

So the ratio of an angle of 30-degree slope will be 1:√3

The ideal way to find the intercepts of an equation with the "x" and "y" axes is to evaluate both values when the image is 0, as described below:

First let's define equation

An equation is the equality that has mathematical expressions on both sides of it, they can be functions, polynomials or others, there are no limits for them.

  Equations can be graphed, just like a function.

Now that we know what an equation is and its structure, let's explain it with an example.

Let the equation

2y = 4x + 2, determine its intersections with the axes "x" and "y".

First, we clear:

y = (4x + 2)/2

y = 2x + 1

0 = 2x + 1

2x = -1

x = -1/2

y = 2(0) + 1

y = 1

As we can see, to find the intercepts, we only have to evaluate the equation when y = 0 and when x = 0.

Knowing merely angle-angle-angle (AAA) does not work, because it can result in triangles that are similar but not congruent.

A set of triangles must have equal sides and angles in order for them to be congruent. The sides of the triangles may or may not be equal in the case of a triangle with all of the corresponding angles equal, or the AAA condition.

Only if the two triangles are similar would the congruence be true for two triangles with identical respective angles. Thus, we are unable to utilize AAA to establish the congruence of two triangles.

In a grouped data,

it is not possible to find the median for the given observation by looking at the cumulative frequencies.

The middle value of the given data will be in some class interval. So, it is necessary to find the value inside the class interval that divides the whole distribution into two halves.

In this scenario, we have to find the median class.

To find the median class, we have to find the cumulative frequencies of all the classes and n/2.

After that, locate the class whose cumulative frequency is greater than (nearest to) n/2. The class is called the median class.

After finding the median class, use the below formula to find the median value.

[tex]Median = l +(\frac{\frac{n}{2}- cf}{f} )*h[/tex]

Where

l is the lower limit of the median class

n is the number of observations

f is the frequency of median class

h is the class size

cf is the cumulative frequency of class preceding the median class.

The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Given is a quadratic equation,

For this case, the first thing we must do is rewrite the polynomial:

x² + 7x - 4 = 0

We use the resolver to solve the problem using quadratic formula;

x = (- b ± √(b² - 4 × a × c)) / (2 × a)

Where,

a = 1

b = 7

c = -4

Substituting the values:

x = (- 7 ± √((7)² - 4 × (1) × (- 4))) / (2 × (1))

x = (- 7 ± √(49 + 16)) / (2×(1))

x = (- 7 ± √(65)) / (2)
