Well you have to find out how many cd is 40% and 30%
30% = 30x.3=9
40% = 30x.4=16
now add 16 and 9
16+9=25 now subtract 25 from 30 and see that you have 5 cd of a different type of music to find that as a % divide 5 by 35 to get .14 I rounded it to the nearest hundreth now move the decimal over 2 spots to get 14%
Step-by-step explanation:
2y+3=5x-18
swap both sides
5x-18=2y+3
add 18 to both sides
5x-18+18=2y+3+18
5x=2y+21
divide both sides by
5x/5=2y+21/5
X=2y+21/5
Answer:
( 1, 0)
Step-by-step explanation:
you know that the slope of the MN line is 1/4 and a slope perpendicular to that is -4/1 ( negative and reciprocal ). then you can either draw a line from point p with the slope -4/1 and fine the point ( 1, 0 ) or you can do it the harder way which is plug the numbers into y=mx+b with 0 being b because you know the x-axis answer will have a y value of 0. (-4=-4x+0) and x is 1.
Answer:
1. C
2. 3 movies
Step-by-step explanation:
1. the step function is discontinuous at C. multiples of 8 greater than 0,
you can see that at 8, 16, 24 ,32, 40, the graph is discontinuous.
2. when x = 25, y = 3.
