Step-by-step explanation:

1. to check the congrency normally distance formula is used. if the distances/ length are equal we say that sides are congurent.

2. if the slope of two lines are equal then both the lines are parallel. if the product of the slopes of two lines equal to one then lines will be perpendicular.

3. diagonals bisect or not can be checked by using midpoint formula.

4. equilateral triangle if the distance of each side is equal so, distance formula can be used.

The graph of a linear function is shown on the grid

monitta

Answer: Choice A

y + 1 = -3(x+2)

=============================

Explanation:

Let's look through the answer choices.

Choices C and D show that the point (2,1) is on the line. But the graph does not show this. So we can rule out choices C and D.

With choice A, the slope is negative and choice B has a positive slope.

The answer must be choice A because the line is going downhill as we move from left to right.

--------------

A common method is to pick two points on the line and compute the slope using the slope formula

m = (y2-y1)/(x2-x1)

Once you know the slope, you would use point slope form

y - y1 = m(x - x1)

the sum of three integers is 92. the second number is three times the first number. the third number is ten less than twice the

Elanso [62]

1st number = x

2nd number = 3x

3rd number = 2x-10

x +3x + 2x-10 =92

6x - 10 = 92

6x =102

x = 102/6

x = 17

1st number = 17

2nd number = 17*3 = 51

3rd number = 17 *2 = 34-10 = 24

17 + 51 + 24 = 92

3 numbers are 17, 51 and 24

For homework Tina is asked to write down the opposite value for each number listed which comparison did Tina write incorrectly

katovenus [111]

In writing down the opposite value of each number, the comparison Tina wrote incorrectly is: Comparison X

<em><u>Recall:</u></em>

Opposite values of a number are numbers that are of the same distance from point zero on a number line.

For example, if a is a number, the opposite of a is -a. Or if -3 is a number, the opposite of -3 is 3 because -3 and 3 are both 3 units away from point zero on a number line.

Thus, Tina's comparison is given in the diagram attached below.

The comparison labelled X is incorrect because -(-9) = 9. Opposite of 9 is -9.

Therefore, in writing down the opposite value of each number, the comparison Tina wrote incorrectly is: Comparison X
