1. Name the pair of congruent sides in the figure below.
Anon25 [30]

Answer:

Note that the sum of the angles in a triangle are 180.

1. B. <R = 180 - 70 -55 = 55. Since <R = <T, then RS = ST

2. D. <J = 180 - 42 -96 = 42 = <K, so JL = KL = 12

3. B. Let the base angle = x. The vertex angle = 2x + 50. The sum of the angles in a triangle is 180, so x + x + 2x + 50 = 4x + 50 = 180 -> 4x = 130 -> x = 32.5.

4. D. Since <S = <Q, RQ = RS. Thus, 2x + 4 = 18 -> 2x = 14 -> x =7

I hope this helps!

What inequality is shown in this graph?
Minchanka [31]

The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality

A student claimed that reflect a triangle in a line, translating a triangle , rotating a triangle, and reflecting it in a point
Nady [450]

If we reflect a triangle in a line, translate a triangle, rotate a triangle, and reflect it in a point result in an image that will be congruent to the original( pre-image) triangle.

This is a problem from triangular geometry. We can solve this problem by following a few steps.

Here a triangle ABC is given and the triangle is at first reflected and then translated, thereafter it rotates and is later reflected.

After all, these processes the value of ∠A, ∠B, and ∠ C remains the same as usual concerning ∠A''', ∠B''', ∠ and C'', as they just changes coordinates not geometric structures.

After all these processes the length of the triangle AB, AC, BD, and A'''B''', B'''C''', C'''A''' remains the same as usual.

∵ We can conclude that ΔABC ≅ ΔA'''B'''C'''

( As AB = A'''B''', BC = B'''C''', ∠ABC = ∠ A'''B'''C''' )

30 POINTS FOR WHOEVER CAN SOLVE THIS!!
Cloud [144]
The two inequalities formed will be:
One for ticket quantity:
x + y ≤ 600

One for funds generated via tickets:
5x + 7y ≥ 3500

Equating x to 330,
5(330) +7y ≥ 3500
y = 265

Checking if the other inequality holds true:
330 + 265 ≤ 600
595 ≤ 600

This inequality is still true so they can sell 265 tickets on the event day and cover their expenses.

Given the parent function
yanalaym [24]

Answer:

Option a is right.

Step-by-step explanation:

Parent funciton is

f(x) = x^3

The new graph is

f(x) = -2x^3

Since there is no change for x, there is no horizontal shift.

BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.

Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2

Option a is right

i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
