T: 8x+19

7x-2(4-2x)+6(5-x)-x+2-(6x+5) = 7x-8+2x+30+6x-x+2-6x-5 = 8x+19

Y: 56-8x

9-(-2-3x)+4(-x+6)-x+12-3(2x-3) = 9+2+3x-4x+24-x+12-6x+9 = 56-8x

What is the solution to the system that is created by the equation y=-x+6 and the graph shown below?
mina [271]
The graph graphed is y=1/2x

so
y=1/2x and y=-x+6
y=y so
1/2x=-x+6
times 2 both sides
x=-2x+12
add 2x both sides
3x=12
x=4

sub back
y=1/2x
y=1/2(4)
y=2

(4,2) is the solution

Express sin(3theta) in terms of sin (theta)
BigorU [14]
3∅ can be rewritten as (2∅+∅)
sin(3∅) = sin(2∅ + ∅<span>)
Opening brackets on the right hand side;
 = sin2</span>∅ cos ∅ + cos2∅sin<span>∅
</span><span>This simplifies to;
 = 2sin</span>∅cos^2∅ + sin∅ (1- 2sin^2∅<span>)
 = sin</span>∅ (2cos^2∅ + 1 - 2sin^2∅<span>)
 = sin</span>∅ (2(1 - sin^2∅) +1-2sin^2∅<span>)
 = 3sin</span>∅ - 4sin^3<span>∅</span>
