Answer 2

For the first one, you got your coordinates backwards.

Answer 3

@SACAPUNTAS thanks

Answer 4

The second one is wrong too.

Answer 5

@shamil98

Answer 6

do you just want the answers?

Answer 7

no. I think the first four are wrong. I had trouble with those

Answer 8

in the 1st one, the recheck your coordinates

Answer 9

in the 2nd one, fixed fee, 26, plus 3.25 * hours, => 26+3.25x
fixed fee, 24 plus 3.50 * hours, => 24 + 3.5x

the functions represent the costs
the costs are the same, when the equations are the same
\(\bf 26+3.25x=24+3.5x\qquad \textit{let us multiply by 100}\\ \quad \\
2600+325x=2400+350x\implies 200=25x\implies \cfrac{200}{25}=x\)

Answer 10

so its 8?

Answer 11

yeap

Answer 12

the 3rd one,. well, you'd just have to solve for "y"

y = -2x/3-3
y = x+2

graph that and then do the shading

Answer 13

the 4th one
y = adults
x = students

700 total for adults and students, so y + x = 700

each adult ticket costs $4.5 so they sold 4.5y
each student ticket costs $2.00, so they sold 2x

total sales was $1200
so
4.5y+2x = 1200

Answer 14

so number 4 is B

Answer 15

@jdoe0001

Answer 16

yeap

Answer 17

is number 5 right?

Answer 18

hmm... graph them.. and see where the shading intersects

Answer 19

is it D?

Answer 20

dunno that one

Answer 21

what about the rest?

Answer 22

didn't check those ones... you said you suspected the 1st 4, so I checked those

Answer 23

well I still want to make sure there right. you dont have to tell me the answers. I just want to know if they are right.

Answer 24

@jdoe0001 ?

Answer 25

@SACAPUNTAS can you check the rest?

Answer 26

No, that's too many. Give me one and I will, though.
