if we notice those tickmarks in the triangle, that simply means that those sides are twins, namely HL = LJ = 5 and so on, that also means that the line cutting them from the opposite vertex is a median.
so we have three medians, meeting at a certain point, namely the centroid.
a particular feature of the centroid is that it cuts all medians in a 2:1 ratio, namely GP : PL are in a 2:1 ratio, therefore
21)
22)
well, we already know from 21) :).
23)
recall, since the lines are medians, both sides on the opposite side are twins, HL = LJ = 5.
24)
if we take a look at the triangle GLJ, is a right-triangle, so we can use the pythagorean theorem on it,
Answer:
d
Step-by-step explanation:
y=-7x+2
m=-7, so that's a negative slope.
b=2, so the y-intercept is (0,2). That's a postiive y-intercept.
Solve 0=-7x+2 to find the x-intercept.
7x=2
x=2/7
The x-intercept is (2/7,0), so that's a positive x-intercept.
3x - 2y = 8
Divide both equation by 3
x = 8 2
- + -- y, y = R
3 3
