Answer:
Step-by-step explanation:
The negative sign in y = -2x + 2 tells us immediately that the y intercept of the graph of this function is (0, 2). If we start at (0, 2) and increase x by multiples of 1, y decreases by 2 in each case (the slope of this line is -2). Thus, we begin a table as follows:
x y = -2x + 2
0 2
1 -2(1) + 2 = 0
2 -2(2) + 2 = -4 + 2 = -2
and so on:
x y = -2x + 2
0 2
1 0
2 -2
3 -4
4 -6
Is it supposed to be equal to something, maybe "0"? You wouldn't be able to solve this without that.
Answer:
not paying 20% means that she DID pay %80
Step-by-step explanation:
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
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.
