Answer:
{-3, 29, 21, 33}
Step-by-step explanation:
Substitute the x values (domain) to find y, do this for all x's-
f(x) = 6(-2) + 9 = -3
f(x) = 6(0) + 9 = 9
f(x) = 6(2) + 9 = 21
f(x) = 6(4) + 9 = 33
Range-
Take the y values and arrange it from least to greatest <em>(this matters and your teacher may most likely count it wrong if you do not put it in increasing order)</em>
{-3, 29, 21, 33}
I’m pretty sure it’s line graph, if not that, bar graph
Hope this helps :D

Answer:
-6.20x-6.20y=-948.6
add this to equation 2
6.20x-6.20x +9.30y-6.20y=1125.30-948.60
3.10y= 176.70
/3.10
y=176.70/3.10
y = 57 number of adult tickets
153-57=96 child tickets
Step-by-step explanation:
child admission is $6.20 : x numbers
adult admission is $9.30 : y numbers
153 tickets were sold
sales of $1125.30 .
x+y = 153.........................1
6.20x+9.30y= 1125.30..............2
Answer:
18=18
Step-by-step explanation:
a=90-b
a=50 mL at 4%
b=40 mL at 40%
check
0.04*50+0.4*40=0.2*90
2+16=18
18=18
