Answer:
(-6, 1)
Step-by-step explanation:
Since DE to DF is 5:8, we need to add 5/8 of the difference in x- and y-coordinates to the coordinates of point D to find point E.
Difference in x from D to F:
-9 - (-1) = -8
5/8 * (-8) = -5
Difference in y from D to F:
-5 - 11 = -16
5/8 * (-16) = -10
x: -1 - 5 = -6
y: 11 - 10 = 1
Answer: (-6, 1)

I think it's the third one sry if I'm wrong
Julia’s score is <em>y</em> and Tina’s score is <em>y</em> + 6.
Step-by-step explanation:
Let us take Julia’s score be <em>y</em>.
First Tina scored 4 points more than Julia, so the expression is <em>y</em> + 4.
Then, Tina earned 2 points as extra credic, now the expression becomes
(y + 4) + 2 = y + 6.
Hence Julia’s score is <em>y </em>and Tina’s score is <em>y</em> + 6.
Answer:
E, F, A, ED, BC, EF, ABC, EDF
Step-by-step explanation:
The angle and side markings show which segments and angles are congruent.
We can make a table of corresponding pairs based on the number of marks:
marks, angle, side
- A and E, DF and BC
- B and D, ED and AB
- C and F, EF and AC
__
This can help us fill in the question numbers:
- ∠E is congruent to ∠A
- ∠F is congruent to ∠C
- ∠A is congruent to ∠E
- ED is congruent to AB
- BC is congruent to DF
- EF is congruent to AC
- 8. ΔABC ≅ ΔEDF
