1) △ABC has A(-2,-2), B(-1,2) and C(2,1). After a dilation centered at the origin, △A'B'C' has A'(-4,-4), B'(-2,4) and C'(4,2).

Sedaia [141]

Answer:

Option (C)

Step-by-step explanation:

If a point is dilated by a scale factor of 'k' about the origin,

Rule for the dilation,

(x, y) → (kx, ky)

By this rule, if ΔABC is dilated to form image triangle as ΔA'B'C',

A(-2, -2) → A'[2×(-2), 2×(-2)]

B(-1, 2) → B'[2×(-1), 2×(2)]

C(2, 1) → C'[2×(2), 2×(1)]

Therefore, scale factor of the dilation of the dilation will be k = 2

Option (C) will be the answer.

Given: KLMN is a rectangle m∠NKM = 58° MP −∠ bisector of ∠KML Find: m∠KPM

PilotLPTM [1.2K]

According to the rule of angles and parallel lines, we can say that ∠NKM and ∠KML are equal because they are alternate angles. Since MP is a bisector, ∠KMP = ∠LMP = 1/2∠NKM = 29°. We know that ∠MKL = 90°-∠NKM = 32°. According to the sum of all angles of the triangle, ∠KPM = 180-(32+29) = 119°.

The graph shows the functions f(x), p(x), and g(x):

Anton [14]

"What is the solution to the pair of equations represented by p(x) and f(x)?" Lines p and f intersect at the point (6,2).

"Write any two solutions for f(x)." That's an odd question! I'd suggest it means to choose any point on the line f(x). One such point could be (1,-3).

"What is the solution to the equation p(x) = g(x)?" p and g intersect at the point (3,6).

PLS HELP WITH ALGEBRA

pantera1 [17]

Answer:

1. 4x(x^2+5x+4)

2. 2x^2(6x^2+13x-8)

3. 2(5x^2+24x-5)

Step-by-step explanation:

The common factor between all the monomials is 4x, so we divide each by 4x.

The common factor between all the monomials is 2x^2, so we divide each by 2x^2.

The common factor between all the monomials is 2, so we divide each by 2.
