Answer:
(0,4)
Step-by-step explanation:
The line AD is a median, because D is the midpoint of BC.
The centroid is the point of intersection of three medians of triangle, we don't need to depict any another median, because we know that centroid divide each median in ratio 2:1 from the vertices of a triangle from which a median was depicted. That's obvious that the median AD was depicted from A. Let the point of centroid be M. AM:MD is 2:1. So we should find the coordinates of D
xD= (xa*1+xd*2)/ (2+1)= ((-4)*1+2*2)/3=0
yd= (ya*1+yd*2)/ (2+1)= (2*1+ 5*2)/3=12/3=4
(0,4)
Answer:
We shouldn't waste our points u know.........
We may start by putting the given equation in slope-intercept from:
We can now easily identify the slope:
Since parallel lines have the same slope (as you already seem to know), any line with equation
is parallel to the given line. By choosing, for instance, , we get:
Answer:
B. 455
Step-by-step explanation:
The order in which the toppings are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
3 toppings from a set of 15. So
455 3-topping sundaes can be made.
Answer:
The vertical one is the y axis and the horizontal one is the x axis.
