Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
y - 5 = -9/2*(x - 4)
y -5 = -9/2x + 9*4/2
y - 5 = -9x/2 +9*2
y-5=-9x/2 + 18
y= -9x/2 + 18 +5
y= -9x/2 + 23 {y =mx+c}
Answer:
A = - 2 and B = - 8
Step-by-step explanation:
A = - 2 and B = - 8 will create infinitely many solutions for this system of equations
When you add both equations together and both sides are equal then the systems have infinitely many solutions
-2x - y = 8
2x + y = -8
--------------------Add
0 = 0
Both sides are equal 0
Infinitely many solutions
The reasonable estimate for the length of side DE is 3 units
Find the diagram of the question attached. The given triangle ABC and BDE are similar triangles.
Using the similarity theorem of a triangle, this is expressed as:
AC = DE
Using the pythagoras theorem to get the length of AC:
AB^2 = AC^2 + BC^2
5^2 + AC^2 + 4^2
AC^2 = 25 - 16
AC^2 = 9
AC= 3
Since AC = DE, hence the reasonable estimate for the length of side DE is 3 units
