To determine the location of a point on a graph, the first number of the ordered pair is a x-coordinate which means the first number you would look for would be the horizontal line, or the x-axis. The second number is the y-coordinate which means that you would look on the vertical line, or the y-axis. You would go on the horizontal line first, then from there go up to the y-coordinate and place your point. (I'm sorry if it's long but you can try to shorten it.)
Hope this helped!
Have a nice day!
Given:
The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).
To find:
Which type of triangle is ΔWXY by its sides.
Solution:
Distance formula:
Using distance formula, we get
Similarly,
Now,
So, triangle is an isosceles triangles.
and,
So, triangle is right angled triangle.
Therefore, the ΔWXY is an isosceles right angle triangle.
Answer:
Point D is at 3 this is the only correct point...
Step-by-step explanation:
Standard Error = standard deviation/sqrt(sample size) = 6/sqrt(50) = 6/7.071 = 0.85
Equation A.
Paul's plumbing: y= 40h+ 90
Perfect plumbing: y= 55h + 60
B:
Pauls plumbing: y= 40(3) + 90.... 310= y
Perfect plumbing y= 55(3) + 60... y= 225
Not the same
