(–6,2) is the possible coordinates of point D if ΔDEF is congruent to ΔABC.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

Shapes are congruent if you can turn one into the other by moving, rotating or flipping.

We can use this symbol  to show that two things are congruent.

Two triangles are congruent if and only if all the corresponding legs are congruent.

The only point that makes the corresponding legs to be congruent is

(–6,2)

because we can match these two triangles by flipping the red one two times and moving it into the blue one.

Answer:

(m,n) is (-2,2)

Step-by-step explanation:

Elimination means that we should rewrite one of the two equations as an expression of one of the variables isolated, and then use that definition isn the other equation.  It is also called "substitution."

Lets use the first equation and rewrite it so that the variable m is isolated:

3m-4n=-14

-4n = -3m-14

n = (3/4)m +(7/2)

Now use this definition of n in the second equation:

3m+2n=-2

3m+2((3/4)m +(7/2)) = -2

3m + (3/2)m + 7 = -2

4.5m = -9

m = -2

Now use m= -2 in either equation to find n.

3m-4n=-14

3(-2)-4n=-14

-6 -4n = -14

-4n = -8

n = 2

The solution of this system of equations is (-2,2).

See the attached graph, with x and y used in place of m and n.

Volume= l*b*h

=7*5*3

=105 cubic inches

Answer:

see below

Step-by-step explanation:

enter the values of -1 & -2 into the equation

so you'll get 2 equations for 2 variables: m & n

when x = -1

1-(m-2)*(-1)-3+n=0 ==> 1+m-2-3+n =0 so m+n=5

when x = -2

4-(m-2)*(-2)-3+n=0 ==> 4+2m-4-3+n =0 so 2m+n=3

use equation 2 subtract equation 1

2m=-2, so m = -1

n= 6

Answer:

Step-by-step explanation:

Given roots of x² -(m -2)x -(3 -n) = 0 are -1 and -2, you want the values of m and n.

Given roots -1 and -2 for a quadratic equation, we know its factored form is ...

  (x -(-1))(x -(-2)) = 0

  (x +1)(x +2) = 0

Then the standard form is ...

  x² +3x +2 = 0

Comparing this to the given equation, we find ...

  -(m-2) = 3   ⇒   m = -1

  -(3 -n) = 2   ⇒   n = 5

Step 1: Calculate the ratio.

The ratio is 77 out of 100.

Step 2: Convert the ratio to a percent.

To convert the ratio to a percent, divide the numerator by the denominator and multiply the result by 100.

Therefore, 77 out of 100 can be written as 77/100 x 100 = 77%.

The conversion process known as "ratio to percentage" aids in turning a ratio into a percentage. As is common knowledge, two quantities of the same unit are compared using the ratio. A percentage, on the other hand, is a particular kind of ratio where the value of the sum is always equal to 100. Let's go over the formula, the value of the ratio to percentage for some of the most commonly used numbers, and several solved examples in depth in this article.

a) The measure of the angle created by the car's turning would be 75°. This is because 4th Street is parallel to 3rd Street, thus the angle formed when the car turns onto King Avenue heading northeast would be a 90° angle, which is the same as the angle between 4th Street and 3rd Street.

b) The measure of the angle created by the car's turning would be 180°. This is because when the car is traveling southwest on King Avenue and turns left onto 3rd Street, it is essentially making a full turn to face the opposite direction.

Use the rules of exponents to divide variables with the same base when dividing monomials. According to this rule, the base should remain in the position (numerator or denominator) where the greater exponent was when dividing variables with the same base after the exponents have been subtracted.

In order to divide a polynomial by a monomial, let's first divide a monomial by another monomial. The monomial should be divided into numerical and variable factors. By deducting the exponents of each y term, divide the coefficients and variables.

Let's go over the three steps that must be completed in order to divide a polynomial by a monomial. Rewrite the issue and divide each polynomial term by the monomial as a first step. Dividing the numbers is the next step. Divide the variables is the third and last stage.

The perimeter of this rectangle is 94, which is the smallest possible perimeter for a non-square rectangle with integer dimensions that has an area that is triple its perimeter.

Let's call the length of the rectangle "L" and the width of the rectangle "W". The area of the rectangle is then L * W, and the perimeter is 2 * (L + W).

According to the problem, the number of square units in the rectangle's area is triple the number of units in its perimeter:

L * W = 3 * (2 * (L + W))

Expanding the right side and solving for L:

L * W = 6L + 6W

L * W - 6L = 6W

L * (W - 6) = 6W

L = 6W / (W - 6)

Since L and W are both positive integers and L can't be equal to W (because the rectangle can't be a square), we know that W must be greater than 6. Let's try W = 7:

L = 6 * 7 / (7 - 6) = 6 * 7 = 42

This gives us a rectangle with dimensions 42 x 7, which satisfies the conditions of the problem.

The perimeter of this rectangle is 2 * (42 + 7) = 94, which is the smallest possible perimeter for a non-square rectangle with integer dimensions that has an area that is triple its perimeter.

We got that the probability that the hand contains 4 cards of the same suit and 1 of another suit = 0.042917

In the given question the hand contains 4 cards of the same suit, and 1 of another suit and we have to find the probability of this.

As we know that in standard card deck have 4 suits and 13 ranks in each suit and each deck have total 52 cards. If 13 ranks separated then 39 cards are left.

So the probability that the hand contains 4 cards of the same suit and 1 of another suit is

Probability =  [tex]\frac{|^{13}C_{4}\times^{39}C_{1}|+|^{13}C_{4}\times^{39}C_{1}|+|^{13}C_{4}\times^{39}C_{1}|+|^{13}C_{4}\times^{39}C_{1}|}{^{52C_{5}}}[/tex]

Probability = [tex]\frac{|715 \times 39| + |715 \times 39|+|715 \times 39|+|715 \times 39|}{2,598,960}[/tex]

Probability = (27,885 + 27,885 + 27,885 + 27,885)/2,598,960

Probability = 111,540/2,598,960
