Answer:
3.12
Step-by-step explanation:
Line up the number in long multiplication form as usual
Multiply each digit on the top by the first to the right on the bottom
Add the products together
Place the decimal the number of digits it is collectively in front of in each factor
Example 5.2 has one behind the decimal and .6 also has one digit behind the decimal collectively that would be two digits behind the decimal.
Answer:
DC=30
CM=15
Step-by-step explanation:
Given
Triangle DEF with C centroid
DM=45 (length of median)
centroid divides median in the ratio 2:1(larger side at vertex)
⇒
DC
⇒DC=30
DC+ CM=DM
30+CM=45
⇒CM=15
So, for this, "x" can equal 5/2 which is fraction form, OR it can be decimal form, which would be 2.5
I hope this helps!
Answer:
(c) y -2 = 6/5(x -1)
Step-by-step explanation:
The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)
_____
<em>Additional comment</em>
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
__
The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).
