To solve for the solution of this system of equations,there are many ways to go about doing it, finding the point where the lines both intersect at.

One of the easiest is substitution, so plug in either one of the equations for the other one.

Y = X+4
Y = -4 + X
X+4 = -4 + X

Then solve for the X value to obtain the X coordinate of the point.

X+4 = -4 + X
X - X + 4 + 4 = -4 + 4 + X - X
8 = 0.
Since after trying to solve for X, we couldn't solve for it, and instead gave us numbers that are not equal to each other, there is no solution to these systems of equations, in other words, they don't intersect at a particular point.

PLZ HELP DUE IN 20 MINS
Artemon [7]

Answer:

a. D and E are similar but not congruent.

Step-by-step explanation:

Let's analyse each statement and determine which is true about the 3 given quadrilaterals:

a. "D and E are similar but not congruent." TRUE.

D is similar to E because, every segment of D is proportional to the corresponding segments of E. The ratio of their corresponding segments are equal.

D and E are not congruent because their segments are not of equal length. Thus, they have the same shape but different sizes.

b. "E and F are similar and congruent." NOT TRUE.

E and F has the same size, hence they are congruent. However, they are not similar, because they don't have the same shape. Their corresponding lengths are not proportional.

c. "D and E are similar and congruent." NOT TRUE.

Since statement (a) is TRUE, statement (c) cannot be true.

D and E are similar because they have the same shape and the ratio of their corresponding sides are the same. D and E are not congruent, because they are not of the same size.

d. "F and D are similar but not congruent." NOT TRUE.

F and D has the same size but the ratio of their corresponding sides are not the same.
