Answer:
Two dotted lines, one solid line
Step-by-step explanation:
The graph of the system of inequalities
will have two dotted lines, one solid line.
To plot the solution set to the inequality with signs < or >, we need to plot the dotted line (because the points of this line are not the solutions to the inequality).
To plot the solution set to the inequality with signs ≤ or ≥, we need to plot the solidd line (because the points of this line are the solutions to the inequality).
The system above has two inequalities with signs < and > and one inequality with sign ≥, so there will be two dotted lines, one solid line.
The inn's per night cost before tax is $220.
Step-by-step explanation:
Given,
Sales tax = 5% =
Per night charges including sales tax = $231
Let,
x be the per night charges.
Per night charges + 5% sales tax of per night = 231
Dividing both sides by 1.05
The inn's per night cost before tax is $220.

Answer:
y= 2/3x + 28/3
Step-by-step explanation:
First, write your equation as y=2/3x+b. Plug in your coordinate into the equation, it should look like this: 6=2/3(-5)+b. Multiply 2/3 by -5 to get -10/3. It should look like this: 6= -10/3+b. Add 10/3 to both sides to get your y-intercept of 28/3. Go back to your original equation and plug 28/3 into b. This is your final equation: y= 2/3x + 28/3. Hope this helped!
Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.
Sorry that was a lot. Hope it helps!
Hey buddy I am here to help!
5. y = ax + b
-5 = a*4 + b
-5 = 4a + b
If we take a as -2
-5 = 4*-2 + b
-5 = -8 + b
b = -5 - (-8)
b = -5 + 8
b = 3
so... a = -2 and b = 3
6. (i) y = 5x - 2
(1,7)
y = 7 & x = 1
7 = 5*1 -2
7 = 5 - 2
7 = 3
so this point (1,7) is wrong
(ii) y = 5x -2
we can take any value for x...
e.g. x = 2
y = 5*2 - 2
y = 10 -2
y = 8
SO answer in this case would be (2,8)
