Ok so I assume
28 and decreased by 12.5%
percent means partst out of 100 so
12.5%=12.5/100=0.125
first find 12.5% of 28 then subtract
0.125 times 28=3.5
decrease
28-3.5=24.5
answer is 24.5
I have no idea but I’ll go with 60% cause there’s no picture
Answer:
9x - 4y = 55
Step-by-step explanation:
The equation for the perpendicular line can be written by swapping the x- and y-coefficients and negating one of them. Usually we choose to negate the one that makes the x-coefficient positive. Here, that process gives ...
9x - 4y = <some constant>
The value of the constant can be found by putting the (x, y) values of the given point into the left-side expression:
9x - 4y = 9·7 -4·2 = 55
9x - 47 = 55
