Hey! This can look pretty confusing but, don’t worry I’m here to help! I actually just studied these.

So basically you’re wanting to solve for Y.
You can calculate this by cross multiplying and the answer to your question is 12.

I know how it is when you need help and you just can’t grasp something, so if you have absolutely anymore questions or concerns, post em in chat and I’ll be happy to try to answer.
Have a great evening and I hope this helped!

The vertices of triangle ABC are A(5,2), B(-1,-6) and C(1,5). If Triangle DEF is similar to Triangle ABC and AB/DE=5, what could

astraxan [27]

Answer:

D(-5,3) and E(-5,1)

Step-by-step explanation:

|AB|² = (-1-5)² + (-6-2)²

|AB|² = 36 + 64

|AB|² = 100

|AB| = 10

AB/DE = 5

|DE| = 10/5 = 2

D(-5,3) and E(-5,1)

|DE|² = (-5+5)² + (3-1)²

|DE|² = 4

|DE| = 2

The four points questions are 5.

Step-by-step explanation:

Total points = 50

Total questions = 15

There are 4 points questions and 3 points questions.

Let,

x be the number of 4 points questions

y be the number of 3 points questions

According to given statement;

x+y=15 Eqn 1

4x+3y=50 Eqn 2

Multiplying Eqn 1 by 3

$3(x+y=15)\\3x+3y=45\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(4x+3y)-(3x+3y)=50-45\\4x+3y-3x-3y=5\\x=5$

As x variable was used for 4 points questions, therefore,

The four points questions are 5.
