waddup

Answer 2

a

Answer 3

a is wrong it is c

Answer 4

i did this question earlier today

Answer 5

Can someone explain please?

Answer 6

if it where c the y int would be -7 which it isnt

Answer 7

either C or D..

Answer 8

i meant d

Answer 9

i'll give you the cvorrect answer

Answer 10

d is the actual answer

Answer 11

cool beans

Answer 12

can you explain how?

Answer 13

well did you see that the shaded in part was not on -7 or 7

Answer 14

yeah

Answer 15

thats how you know that it is not any of those

Answer 16

ohh ok

Answer 17

HA I WAS RIGHT..!!! BOOM SHAKALAKA.. *clears throat* anyways.... its not A cuz 2x + y is going to be greater than 7.. its not B cuz it had subtraction instead of addition and its not C cuz it wouldn't be less than a -7 so it would be D "the correct inequality is not listed"

Answer 18

was that all?

Answer 19

Thank you guys so much! (:

Answer 20

yeah that was it

Answer 21

your welcome

Answer 22

welcome :)

Answer 23

pick 2 points on your line
(1,5)...x1 = 1 and y1 = 5
(0,7)...x2 = 0 and y2 = 7
slope = (y2 - y1) / (x2 - x1)
slope = (7 - 5) / (0 - 1)
slope = 2/-1
slope = -2

y = mx + b
slope(m) = -2
(1,5)...x = 1 and y = 5

y = mx + b
5 = -2(1) + b
5 = -2 + b
7 = b

so your equation is : y = -2x + 7
2x + y = 7
shading is below the line so it is less then
2x + y < 7


I think it is A

Answer 24

@texaschic101
I believe Mathematica agrees with your conclusion.\[\text{Reduce}[2 x+y<7]\to y\in \mathbb{R}\land x<\frac{7-y}{2} \]

Answer 25

The answer wasn't D ):

Answer 26

when i did it got it wrong and it showed me the correct answer was that

Answer 27

I think it was A but it ok

Answer 28

ok
