Let’s first make a blank equation in slope-intercept form: y=mx+b
To find the slope, we find the perpendicular slope to 4x+2y-7=0. First, change this to slope-intercept form:
4x+2y=7
2y=7-4x
y=-2x+(7/2)
The slope of this line is -2, so the perpendicular slope will be the opposite inverse, or 1/2. This is the first component.
Second, to find the x-intercept of 2x+3y-12=0, we have to set y=0 and solve:
2x+3(0)=12
2x=12
x=6 or (6,0)
So in total, we need a line with a slope of 1/2 passing through (6,0). Plug this back into y=mx+b:
0=1/2(6)+b
0=3+b
b=-3
So in total, the equation is y=(1/2)x-3.
So, we know that 30% of 100 is 30. 50 is HALF of 100 so we can cut the 30 into half and we get a $15 dollar discount. :)

Answer:
9000
Step-by-step explanation:
10^3 means 10*10*10 which = 1000
1000*9 equals 9000
an easier way to think of this is just look at the exponet and add that many zeros to 9
