Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16
pishuonlain [190]

y =  - 3(x - 2) ^{2}  + 4
y =  - 6x + 16
distribute the -3 and the square into the first equation
y =  - 3x ^{2}  + 12x - 8
y =  - 6x + 16
multiply the second equation by 2
y =  - 3x ^{2}  + 12x - 8
y =  - 12x + 32
add the equations together
y =  - 3x ^{2}  + 24
factor out -3
y =  - 3(x ^{2}  - 8)
factor inside parenthesis
y =  - 3(x +  \sqrt{8} )( x -  \sqrt{8})
refine
y =  - 3(x + 2 \sqrt{2} )(x - 2  \sqrt{2} )

Graph the equation <br><br>2x + 3y = 9
jeka57 [31]

2x + 3y = 9\\3y = -2x + 9\\y = -\frac{2}{3}x + 3

Look at the graph picture I attached

y = mx + c

c is the intercept, which is why the graph crosses the y-axis at +3

to find where it crosses the x-axis, we make y = 0

y = 0\\\to -\frac{2}{3}x + 3 = 0\\-\frac{2}{3} = -3\\\frac{2}{3}x = 3\\2x = 9\\x = \frac{9}{2}\ \ (=4.5)
