Answer:
f(3) = -6
f(-3) = -12
f(0) = -9
Step-by-step explanation:
Substitute each number for x.
f(3) = 3 - 9 = -6
f(-3) = -3 - 9 = -12
f(0 ) = 0 - 9 = -9
Answer:
183590
Step-by-step explanation:
1/2(600)^2+6(600)-10
1/2(360000)+6(600)-10
180000+3600−10
183590
Answer:
-2
Step-by-step explanation:
Sincwe perpendicular slope are the opposite reciporcal
X= adults
y=children
x+y=20
x=20-y
18x+12y=324
18(20-y)+12y=324
360-18y+12y=324
-6y=324-360
-6y=-36
y=-36/-6
y=6
x=20-y
x=20-6
x=14
14 adults and 6 children
