y=15

5y-20=2y+25 move terms

5y-2y = 25+20 calculate like terms

3y=45 divide both sides by 3

You would make the equation 5y-20=2y+25 and then solve

You would add both sides by 20

5y=2y+45

Then you would add both sides by -2y

3y=45

finally you will multiply both sides by 1/3 and get 15 as Y

y=15

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.
ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

Exp\ 1:3m-4n\\Exp\ 2: n^2-m

The values are:

m=5\\n=-2

Putting the values in expression 1:

3m-4n\\=3(5)-4(-2)\\=15+8\\=23

Putting the values of m and n in second expression

n^2-m\\=(-2)^2-5\\=4-5\\=-1

Multiplying both expressions:

(3m-4n)(n^2-m)=23* (-1)=-23

Hence the correct answer is C) -23

Which line is the line of reflection?<br><br>A. a<br>B. b<br>C. c<br>D. d
Leto [7]
The line of reflection is b

You can see it much easier if take away all the clutter. Redraw the diagram and take way a d and especially c.

You should be left with only line b and the two triangles. You can see it much easier if you do that. Then just look at the parallel lines of the triangles. They are right across from each other.

Explain why (cos((theta))? + (sin((theta))2 = 1
frez [133]

Imagine a right triangle where a and b are the legs and c is the hypothenuse.

Pitagora: a²+b²=c²

Divide by c

(a/c)²+(b/c)²=1

But a/c=sin(B) and b/c=cos(B)

Thus sin² + cos² = 1
