What is the difference between a system of equations and a system of inequalities?
Expressions can be expressed as equations or as inequalities.
The difference is that the variables in a system of equation have one solution each, while in a system of inequalities, the variables have a range of values.
Let the system of equation be:
[tex]\mathbf{ax + by = c}[/tex]
[tex]\mathbf{dx + ey = f}[/tex]
Let the system of inequality be:
[tex]\mathbf{ax + by < c}[/tex]
[tex]\mathbf{dx + ey > f}[/tex]
Both systems can be solved using the same method, such as: graphs, substitution and elimination.
However, the difference is that:
In a system of equation, the variables can have one solution each, while in a system of inequalities, the variables have a range of values.

Question 2
Find three consecutive odd integers whose sum is 99.
Answer:
31, 33, 35
Step-by-step explanation:
Let 2n+1 be the first odd number. What will the next one be? Add two:
Let 2n+3 be the next odd number. Again, what is the next one? Add two:
Let 2n+5 be the third odd number.
The sum of those three numbers must be 99. You don't have to have the parenthesis here, but I think they help clarify where everything comes from.
(2n+1) + (2n+3) + (2n+5) = 99
Add like terms, and solve for n:
6n + 9 = 99
6n = 90
n = 15
The three odd numbers we want are:
2(15)+1 = 31
2(15)+3 = 33
2(15)+5 = 35
Double check: 31+33+35 = 99?

If you were going to solve -3(x + 5) = 27, what is the first step that you would do? Why did you start there?
Answer:
Step-by-step explanation:
Multiply -3 for x and for 5
-3x-15=27
When you have this type of equation the first thing you do is take off the parentesis
Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!!
PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!! I DONT KNOW HOW TO GRAPH SO CAN YOU SHOW ME HOW TO DO IT PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!! PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!! PLS DRAW IT
Answer:
(images to help with graph are below)
Step-by-step explanation:
okay! so once you get the hang of this, it is super super easy.
so the y-intercept is a point on that long line going up and down on the graph. it shows where the line intersects the middle!
so here it says that the y-intercept (y-int for short) is 2. so we will simply mark a little point on 2.
now the slope. the slope is -4. this can be written as -4/1. the -4 is on the top so i represents the y values. and the 1 is on the bottom so it represents the x values.
we know that when graphing, x goes from side to side and y goes up and down.
if an x value is positive you move it to the right (forwards), if it is negative you move it to the left (backwards). if a y value is positive you move it upwards, if it is negative you move it downwards. so we want to start graphing with our x.
The x value is 1 (because it is in the bottom of the slope! -4/1!). So we will move one point from the y-int (the point we marked).
Now for the y values. The y value is -4 (again, taken from the -4/1. the top number is the y value). FROM THE PLACE WE LEFT OFF FOR THE X VALUES (we left off at point (1,2) because we moved it one to the right!), we will move 4 points DOWN because it is negative (-4). Mark this place with a dot!
We should now have the points (0,2) and (1,-2) marked with a dot. draw a line through the 2 dots! this is ur finished graph. notice how the line intersects the middle on the y-intercept!! that will always happen.
Lastly, the equation! the formula for slope intercept form is y=mx+b
m is always your slope. b is your y-int. and y and x stay blank (for now. in the future you might use those spots). so simply fill in m and b!
the slope is -4. so m = -4
the y-int is 2. so b = 2
the finished equation should look like this:
y = -4x + 2
I hope this helped !!!
Wesley wants to have at least $50 to spend each day of his 7-day vacation. He plans to save $30 each month for 12 months. Which of the following shows that Wesley will save enough money for his vacation? Choose all that apply.
Answer:
i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.
Step-by-step explanation:
I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.
A collect call costs $5.99 to connect plus 99 cents per minute. What is the cost of a 6 minute call?
Answer:
$11.93
Step-by-step explanation:
You can write an equation to represent this scenario, where x is the number of minutes spent on the call and y is the total cost of the call.
[tex]y=0.99x + 5.99[/tex]
Plug in 6 for x:
[tex]y=0.99(6)+5.99[/tex]
Multiply 6 x 0.99, representing the fact it costs 99 cents per each minute spent on the call:
[tex]y=5.94+5.99[/tex]
Add the sum of the $5.99 cost to connect the call, plus the charge ($5.94) for spending six minutes:
[tex]y=11.93[/tex]
Your answer is $11.93!

Step-by-step explanation:
The length of the two legs of a right triangle are 18 cm and 24 cm.
What is the length of the hypotenuse of the triangle?
O A. 30 cm
OB. 36 cm
OC. 42 cm
D. 48 cm
Answer: 30 cm
Step-by-step explanation: Take note that ^2 means to the second power.
a^2 + b^2 = c^2 (hypotenuse)
18^2 + 24^2 = c^2
324 + 576 = c^2
900 = c^2
To find the length of c you have to find teh square root of 900.
√c^2 = √900
c = 30
The length of the hypotenuse is 30 cm!
