Identify the type of conic section that has the equation 9x2+ 16y2 = 144 and identify its domain and range.

Setler [38]

9 x² + 16 y² = 144 / : 144 ( divide both sides by 144 )
x²/16 + y²/ 9 = 1 ( ellipse )
a² = 16, a = 4
b² = 9, b = 3
Answer:
B ) ellipse;
Domain : { -4 ≤ x ≤4 }
Range: { -3 ≤ y ≤ 3 }

Given the Standard Form of linear equation 5x - 2y = 10, find its x-intercept and y-intercept: (show your work)

Rzqust [24]

We have that
5x - 2y = 10

we know that

Part A)
the x-intercept is when y=0
then
5x - 2y = 10------> 5x=10--------> x=10/5------> x=2

the answer Part A) is
the x intercept is the point (2,0)

Part B)
the y-intercept is when x=0
then
5x - 2y = 10------> -2y=10------> y=-10/2-----> y=-5

the answer Part B) is
the y intercept is the point (0,-5)

see the attached figure

Explain the difference between AAS congruence and ASA

Orlov [11]

ASA - If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent.

AAS - If two pairs of angles of two triangles are equal in measurement, and a pair of corresponding non-included sides are equal in length, then the triangles are congruent.
