Answer:
The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

which number line correctly shows .8 + .3
Answer:
The second line.
Step-by-step explanation:
The line starts off at 0 and goes up to 0.8.
As you can see it goes up .3 more.
.8 + .3 = 1.1
just as 8 + 3 = 11 but with decimals.
2xy-yz=8 solve for z
The solution of the equation in terms of z will be; z = 2x - 8/y
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given the equation as;
2xy-yz=8
Now we have to solve for z;
2xy-yz=8
-yz = 8 - 2xy
Then divide by y on both sides;
z = 2xy/y - 8 / y
z = 2x - 8/y

5x -4(x - 3) - 8 = Ax + B
Answer:
12= ax - x + b
Step-by-step explanation:
5x -4(x - 3) - 8 = ax + b
5x -4x + 12 - 8 = ax + b
x + 12 = ax + b
12= ax - x + b

There are 133 students at a small school and 23 of them are freshmen. What fraction of the students are freshmen?
Answer:
23/133
Step-by-step explanation:
If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.
The total number of freshmen in the school is 23/133
The number of students in the small school is 133
23 out of the 133 students are freshmen
Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133
Fraction of freshmen is 23/133

Answer:
It is a vertical line at x = 0
Step-by-step explanation:
An equation of a line in a slope-intercept form is y=mx+b
So with the coordinates given, we must find the slope (m), and the y-intercept (b).
In order to find the slope using these coordinates,
we have to use the formula (y2-y1)/(x2-x2).
So the slope would be -3 - 4 / 0.
Because the denominator is 0, the slope would be undefined.
It is easier to see the equation/graph by graphing the coordinates on the coordinate plane. You will see that it is a straight vertical line down x=0.
Hello there! :)
We can use the formula:
[tex]\frac{y2-y1}{x2-x1} \\[/tex]
First, let's take a look at the x-coordinates. They are the same, aren't they?
If the x-coordinates are the same, then the slope is undefined.
Put the x-coordinates into the formula. It turns out that we divide by 0, and division by 0 is undefined.
Hope this helps!

To rent a certain meeting room, a college charges a reservation fee of $34 and an additional fee of $9.90 and hour. The math club wants to spend less than $123.10 on renting the meeting room. What are the possible amounts of time that they could rent the meeting room? use t for the number of hours the meeting room is rented
Answer:
9 hours
Step-by-step explanation:
Firstly,
Minus $123.10 with $34
123.10-34
= 89.10
(bcuz $34 is the reservation fee)
Secondly,
Divide $89.10 with $9.90 to determine the hours
t = 89.10/9.90
= 9
Last answer = 9 hours
