4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.
Hope I helped!
Answer:
The unique intersection point for the given functions which is at x = 0.
The intersection point is (0,0)
Step-by-step explanation:
We are given the following information in the question.

We have to find the intersection point.
Equating the two equations we get,

Since the quadratic equation gives complex root, thus there is a unique intersection point for the given functions which is x = 0.
The attached image shows the graph for the given function.
The red line represent f(x) and blue line represent g(x).
The intersection point is (0,0)
Answer:
a) AAS b) SAS d) LL f) LA
Step-by-step explanation:
Given is a diagram containing two right triangles.
ABC, DEF are the triangles
Given that
AB=DE
AC=DF
Angle A = Angle D (right angle)
Angle B = Angle E
Hence we have for two sides, one angle so ASA
Or two legs and containing angle hence SAS
Also right triangle, one acute and one leg so LA axiom
Besides, two legs equal in right triangle, so LL axiom
