A carpenter makes legs for 3-legged stools and 4-legged tables. He makes a total of 57 legs.
Viefleur [7K]
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!

Prove : the graphs of the function f(x)=x4<br> and g(x)=x3-x2 have aunique intersection<br> point.
vagabundo [1.1K]

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.

f(x) = x^4\\g(x) = x^3-x^2

We have to find the intersection point.

Equating the two equations we get,

x^4 = x^3 - x^2\\x^4 - x^3 + x^2 = 0\\x^2(x^2-x +1) = 0\\x^2 =0, x^2-x +1 = 0\\x = 0, x = 0, x^2-x +1=0

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)

Based only on the information given in the diagram which congruence theorem or postulates could be given as reasons why abc = de
svet-max [94.6K]

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
