Use the coordinates of the plotted points to complete the calculation below. Pay attention to negative signs.

MArishka [77]

Answer:

3
1
-3
1
-3

Step-by-step explanation:

The change in y is the difference in y-coordinates between the lower right point and the upper left point. Similarly, the change in x is the difference in the x-coordinates of those points.

$\text{Slope}=\dfrac{\text{change in y}}{\text{change in x}}=\dfrac{\boxed{3}-6}{2-\boxed{1}}\\\\=\dfrac{\boxed{-3}}{\boxed{1}}\\\\\\=\boxed{-3}$

Find the value of x and then the measure of Arc XYZ and Arc XZ. Show work on a piece of paper.

Westkost [7]

Given:

The measure of arc XY is (31x)°

The measure of arc YZ is (35x - 16)°

We need to determine the value of x, measure of arc XYZ and arc XZ.

Value of x:

From the figure, it is obvious that the arcs XY and YZ are congruent.

Thus, we have;

$31x=35x-16$

Subtracting both sides by 35x, we have;

$-4x=-16$

$x=4$

Thus, the value of x is 4.

Measure of arc XYZ:

The measure of arc XYZ is given by

$m \widehat{XYZ}=m \widehat{XY}+m \widehat{YZ}$

The measure of arc XY is given by

$m \widehat{X Y}=31(4)=124^{\circ}$

The measure of arc YZ is given by

$m \widehat{Y Z}=35(4)-16=124^{\circ}$

Hence, the measure of arc XYZ is given by

$m \widehat{XYZ}=124^{\circ}+124^{\circ}=248^{\circ}$

Therefore, the measure of arc XYZ is 248°

Measure of arc XZ:

The measure of arc XZ is given by

$m \widehat{XZ}=360^{\circ}-m \widehat{XYZ}$

Substituting the values, we have;

$m \widehat{XZ}=360^{\circ}-248^{\circ}$

$m \widehat{XZ}=112^{\circ}$

Thus, the measure of arc XZ is 112°

Write a problem situation to match the inequality: x divided by 4 less than or equal to 5

Paha777 [63]

Answer:

yes it is ill explain

Step-by-step explanation:Find the student's error in solving the following inequality.31 < -5x + 625 < -5x-5 < x

The student should have added 6 to both sides instead of subtracting it.

The student divided 25/-5 incorrectly.

The student should have switched the direction of the inequality sign to get -5> x for a final answer.

Find the student's error in solving the following inequality.2 < -3x -4 < 56 < -3x < 5-2 > x > -5/3

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

The student divided 6/-3 incorrectly.

The student should not have switched the direction of the sign in the final step.

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

Which answer choice is a solution to the inequality ?

Identify the property used in each step of solving the inequality .

Step 2: Addition property

Step 3: Multiplication property

Which numbers are solutions to the inequality 2x - 1 > x + 2? Check all of the boxes that apply.

4, 5

If x < 5 and x > c, give a value of c such that there are no solutions to the compound inequality. Explain why there are no solutions

Sample response: The value of c could be 5 or any number greater than 5.

The solution is the intersection of both solution sets of the given inequalities.

The solutions of the compound inequality must be solutions of both inequalities.

A number cannot be both less than 5 and greater than 5 at the same time.

Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 5 -10.
