How many times do the graphs ofthe equations y = 2x + 4 andy = -x + 4 intersect?
1 answer:
Answer:
The graphs intersect one time
Step-by-step explanation:
we have
----> equation A
----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The graphs intersect only at one point
so
The system has only one solution
The intersection point is (0,4)
therefore
The solution is x=0, y=4

Given:
The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).
The rule of dilation is:
The image of triangle MNP after dilation is M'N'P'.
To find:
The coordinates of the endpoints of segment M'N'.
Solution:
The end points of MN are M(-4, 6) and N(2, 6).
The rule of dilation is:
Using this rule, we get
And,
The endpoints of M'N' are M'(-6, 9) and N'(3, 9).
Therefore, the correct option is B.
