Answer:

To prove that triangle ABF is congruent to triangle EDG, we need to show that the three sides of triangle ABF are congruent to the corresponding three sides of triangle EDG.

Since we are given that BC is congruent to DC, AB is congruent to ED, and AG is congruent to EF, we can conclude that the three sides of triangle ABF are congruent to the corresponding three sides of triangle EDG. Therefore, triangle ABF is congruent to triangle EDG.

An angle is a figure in plane geometry that is created by 2 rays and lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

In relation, the y values represents the range of the relation

The relation is defined as the relationship between set of ordered pairs. So generally we can say that the relation is defined as the relationship between x values and y values

We know the domain is the set of all inputs of the relation, that means the domain consist of the x values of the relations

Similarly, the range is the set of all outputs of the relation, that means the ranges consist of the y values of the relations

For example

The relation {(1, 2), (3, 4), (5, 6)}

Here x value = {1, 3, 5}

The y value = {2, 4, 6}

Therefore, the y values represents the range

The correct slope of the line is 5/2 and the mistake made by Luis is that he didn't correctly interpret the scale of both x and y axes.

To find the slope, we will divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

By looking at the given graph, we could easily suspect that the slope is 1/2, but then we have to look at it closely to get the correct thing.

The y-axis shows that 1 unit represents 5 while for the x-axis, 1 unit represents 1.

To get the slope, we need two points on the line (w, x) and (y, z), and the slope is given by the quotient:

m = (z - x)/(y - w)

Looking at the graph we can see that the points (0, 5) and (2, 10) are on the line, and as such the slope is;

m = (10  - 5)/(2 - 0) = 5/2

The slope of the linear equation is 5/2.

Answer:

375 Adult tickets

434 Student tickets

Step-by-step explanation:

Let A and S be the numbers of Adult(A) and Student(S) tickets sold.  We are told that A+S= 809.

We also learn that A + 59 = S [59 more student tickets sold than adult tickets]

Rearrange the last expression to isolate one of the two variables, A or S.  I'll isolate A:

A = S - 59

Now use this expression for A in the first equation ("substitution").

A + S = 809

(S - 59) + S = 809

2S = 868

S = 434

From A + S = 809, we can find A:

A + S = 809

A + 434 = 809

A = 375

Check:   Does 375 + 434 = 809??  YES

There were 375 Adult and 434 Student tickets sold, for a total of 809 tickets.

The largest possible area for the right triangle is 1250 in² in which the sum on the lengths of the two shorter sides is 100 in.

we know that in a right triangle the two shorter sides are the base and the perpendicular. Here we have to find the largest possible area of the triangle in which the sum of the shorter sides is 100 in.

Let the base and perpendicular be x and y respectively.

Therefore,

x+y = 100

  y = 100 -x

Also, Area A

= 1/2 xy

= 1 x(100-x)/z

= 100x-x²/2

so the coordinate of vertex = -b/2a

= - 50/2(1-1/2)

= 50

Also,

y = 100-50 [Putting the value of x in equation 1]

= 50

Therefore Maximum, area:

= 1/2 (50)(50)

= 1250 in²

Hence we get the required maximum area.

b) The Probability of getting a sum of 10 is 1/12.

c) The Probability of getting a sum of 6 or 10 is 2/9.

Probability:

Probability is the branch of mathematics that deals with numerical descriptions of the likelihood of an event occurring or the likelihood of a statement being true. Probability is a number between 0 and 1, with 0 generally indicating impossibility and 1 indicating certainty [Note 1][1][2]. that an event will occur. A simple example is tossing a fair (unbiased) coin. Since the coin is fair, the two outcomes (heads and tails) are equally likely. The probability of heads is the same as the probability of tails. Since no other outcome is possible, the probability of heads or tails is 1/2 (also written as 0.5 or 50%).

Probability = (number of desired outcomes / number of all possible outcomes)

Roll of Dice: Green and Red.

(a) The  probability of totaling 6:

Number of outcomes needed = 5

Therefore,

P(sum of 6) = 5/36

b) The probability that the total is 10

Number of outcomes required = 3

Therefore,

P(sum of 10) = 3 / 36 = 1/12

c) The probability that the sum is 6 or 10:

P(sum is 6) + P(sum is 10)

(5/36) + (1/12) = (5 + 3) / 36

The function equation represented by the graph is f(x)=1/4x-3.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=10x+4. Where:

m= the slope.

b= the constant term that represents the y-intercept.

For the given example: m=10 and b=4.

From the graph is possible to see the following coordinates points: (0,-3) and (4,-2). Applying the standard form for the linear equation, you can write:

-3=0*m+b (1)

-2=4*m+b (2)
