1) correct
2) -3
3) 15/7
4) -10
Answer: Angle T is larger than angle S. So by the side opposite to angle to (side RS) is longer than the side opposite to angle S (side RT). Therefore, side RS is longer than side RT.
Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =
= - 2 log ( base 2 ) 2 = ( because : log x^n = n log x )
= ( - 2 ) * 1 = ( because: log (base x) x = 1 )
= - 2
Addign trinomials (2x+4xy+8z)+(8x+5xy+23z) all you have to do is combine the like terms 2x and 8x= 10x, 4xy+5xy=9xy, and 8z+23z=31z. so the simplified answer to adding the trinomials would be 10x+9xy+31z.
Subtacting trinomials (4x+9y+3) - (-1+3x-2y) .
When doing subtracting you still combine like terms but this time you change the sign before every term. If that is confusing, just pretend there is a negative 1 infront of parenthases and multiply that before you subtracts the two trinomials. so...
4x - 3x= x, 9y+2y=11y and 3+1=4. so simplified answer of the subtraction would be x+11y+4
I hope this helped :) Good luck !
Answer is:
y = 2|x - 3|
when x = 3, y = 0 so (3,0)
when x = 2, y = 2(1) = 2 ; (2, 2)
when x = 4, y = 2(1) = 2; (4, 2)
