First change the equation into y-intercept form. This form will make it clear when the line you are graphing intersects the y - axis and what the slope (more or less the angle the line is at) is
3x+4y= -12
4y= -12-3x
4y=3x-12
Y=(-3/4)x-3
Answer:
The value of the expression Start Fraction 2 x squared Over x End Fraction plus x (100 minus 15 x) when x = 5 is 119.
Step-by-step explanation:
So according to the question statements
6% of the $40k and 7$ of the second $40k and 9% ammount of the $80k
the answer would be
40000 * 0.06
+ 40000 * 0.07
+ 25000 * 0.09
= 270250
