Answer :
Step-by-step explanation:
A linear inequality in two variables is given to us and we need to plot it's graph .So the the given inequality is ,
So firstly let's simplify out the inequality for easy plotting of the graph .
Now let's put some values of x to get values of y .
• Firstly put x = 0 then we get , y is greater than or equal to 0+5/5 (-1) = 5/5(-1) = -1 . Hence we get y ≥ (-1) .
• Secondly put x = 1 , then we get , y is greater than or equal to 1+5/5(-1)=6/5(-1) = -6/5 . Hence we get y ≥ -6/5 .
• Thirdly put x = -1 , then we get y is greater than or equal to -1+5/5(-1) = -4/5 . Hence we get y ≥ -4/5
• Fourthly put x = (-5) , then we get y is greater than or equal to -5+5/5(-1) = 0 .Hence we get y ≥ 0 .
With reference to these let's plot a graph . For the graph kindly refer to the attachment :) .
Here in the graph the red area shows the possible values of x and y .
-2x + y = 8
y = 2x + 8
now sub in 2x + 8 for y in the other equation
3x + 2y = 2
3x + 2(2x + 8) = 2...distribute the 2 thru the parenthesis
3x + 4x + 16 = 2
7x = 2 - 16
7x = - 14
x = -14/7
x = -2
now sub -2 in for x in either equation to find y
-2x + y = 8
-2(-2) + y = 8
4 + y = 8
y = 8 - 4
y = 4
solution is : (-2,4)
Answer: 1-250(+80-18)=-188
Step-by-step explanation: the submarine starts at sea level, goes down 250 feet (-250). rises 80 feet (-170). descends 18 feet (-188). i don't know if this is correct or not. i haven't learned descending yet so idk- i think it's right i'm not sure. i don't know if this is right i'm so sorry.
if it is
4|6-2a|+8 is greater or equal to 24 than i think u would put a filled circle on -1 and a line to the right side ---->
