Answer:
D:y+9=-4(x-4)
Step-by-step explanation:
The positive 9 comes from the top of the graph and its -4 because its on the lower half of the graph.
Solution:
a=-2 b=1 c=4 d=0
Analysis:
When we multiply a matrix by a constant, we multiply each term of the matrix by the constant.
In this case, as we need to find the value of the initial matrix, we can divide each term of the matrix by the constant. In this case, let´s divide by -5
So, it would be:
a=10/-5 a=-2
b=-5/-5 b=1
c=-20/-5 c=4
d=0/-5 d=0

Answer:
Length of DE is 25.
Step-by-step explanation:
Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.
