Answer:

B 5 *(x+y)

C (x-y) *(x+y)

Step-by-step explanation:

A. x+y There is not product here Remember product is multiply

B 5 *(x+y)

There are two factors and they are multiplied

5 is one factor (x-y) is the other

C (x-y) *(x+y)

There are two factors and they are multiplied

(x-y) is one factor and (x+y) is the other factor and they are multiplied

D x*y*z

There are three factors multiplied here

A movie theater has increased their ticket prices. They are shown below

hram777 [196]

Answer:

k = 12

Step-by-step explanation:

Given in the question,

Cost of the the movie tickets is proportional to the number of tickets sold.

Cost of movie tickets (C) ∝ number of tickets sold (T)

C ∝ T

C = kT

Here 'k' is a proportionality constant.

Since, line given in the graph passes through a point (5, 60)

60 = k(5)

k = $\frac{60}{5}$

k = 12

Therefore, value of proportionality constant is 12.

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near

olga2289 [7]

Use the calculator to graph the function y = $2x^2+ 25x + 3$

In the graph , the coordinates of the vertex is the turning point of the graph.

Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.

There will be only one turning point for parabola

Turning point is the vertex

To find vertex we use formula x= $\frac{-b}{2a}$

y = $2x^2+ 25x + 3$

a=2, b= 35

$x =\frac{-25}{2*2} =\frac{-25}{4}$ = -6.25

Now plug in $\frac{-25}{4}$ in f(x)

$y= 2(\frac{-25}{4})^2+ 25(\frac{-25}{4}) + 3$

Take common denominator

$y= \frac{625}{8}+ (\frac{-625}{4}) + 3 =\frac{625-1250+24}{8} =-\frac{601}{8}$ = -75.125

So coordinates of turning point is (-6.25, -75.13)

The graph is attached below.

Answer:

1. ∠A and ∠B are right angles. Given

2. m∠A = m∠ B All right angles are congruent.

3. ∠BEC≅ ∠AED Vertical angles are congruent

4. ΔCBE ~ ΔDAE AA

Step-by-step explanation:

A proof always begins with the givens.

1. ∠A and ∠B are right angles. -------------->Given

2. m∠A = m∠ B are equal since-----------> All right angles are congruent.

3. ∠BEC≅ ∠AED are also equal since---->Vertical angles are congruent

4. ΔCBE ~ ΔDAE since two angles are equal----------> AA
