Which statement can john use this figure to prove
Brums [2.3K]

Answer:

The correct option is;

The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

Step-by-step explanation:

With the assumption that that the question meant that ΔACD and ΔBCD are congruent, we have;

Segment \overline {AC} is congruent to segment \overline {BC} by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Similarly, segment \overline {DA} is congruent to segment \overline {DB} by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Therefore, the points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

-3x+2y=6 Find the intercepts. Show your work.
Arte-miy333 [17]

Answer:

The x-intercept is (-2,0)

The y-intercept is (0,3)

Step-by-step explanation:

An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

-3x+2y=6\\-3x+2(0)=6\\-3x=6\\x=-2

So, the x-intercept is (-2,0).

Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

-3x+2y=6\\-3(0)+2y=6\\2y=6\\y=3

Thus, the y-intercept is (0,3).

daser333 [38]
The metric table goes millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. If you wanted to change it to centimeters, the answer would be 8,340,000. In kilometers, this is 83.4 kilometers. Hope this helps!
