Answer:
x > 4
Step-by-step explanation:
Find the set of values that x may take on that makes this inequality true.
Start by subtracting 2x from both sides, which will simplify the inequality and isolate x on the left side: 3x > 12.
Further isolate x by dividing both sides by 3:
x > 4
Answer:
x=1
Step-by-step explanation:
Look at 3*x-x+2=4
Eliminated similar terms 3*x,-x
It becomes (3-1*x+2=4
Look at (3-1)*x+2=4.
Added fractions or integers together
It becomes (2)*x+2=4
Look at (2)*x+2=4
Remove unneeded parentheses around factor 2
It becomes 2*x+2=4
Look at 2*x+2=4
Moved these terms to the left -4
It becomes 2*x+2-4=0.
Look at 2*x+-2=0
Added fractions or integers together
It becomes 2*x+-2=0.
Look at 2*x+-2=0
Removed extra sign in front of -2
It becomes 2*x-2=0
Look at 2*x-2=0.
Solved linear equation 2*x-2=0 equivalent to 2*x-2 =0
It becomes 0=0.
Result: 0=0
This is an equation! Solutions: x=1.

Write the equation represented by the graph below.
Answer:
y=3/10x
Step-by-step explanation:
First, use the formula y2-y1/x2-x1. Pick any two points from the line to put into this formula. In this case, I would pick (0,0) and (20,6) cause I'm lazy lol. Plot these points into the formula. It would look like this 6-0/20-0. Simplify this to get 6/20. The GCM of 6 and 20 is 2 so divide 2 in each side to get 3/10. Because the y-intercept is on 0, there is no y-intercept. Therefore, the equation is y=3/10x

The equation of the line passing through points will be; y = 0.3x - 12
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.
Consider that the graph shows a straight line passing through points (20, 6), (40, 12), etc.
However, only two points (20, 6), (40, 12) are sufficient to obtain the equation of the line.
The equation of the line passing through two points is given by,
y - 6 = 6/20 (x - 20)
So, the equation of the line passing through points will be,
y = 0.3x - 12
Thus, the required equation is y = 0.3x - 12

which is the graph of y=3/4x -3
Answer:
A
Step-by-step explanation:
the formula y = mx + b is used here
lets look at the formula we were given
y = 3/4x -3
the first number we see, 3/4x is the slope of the line, where 1 = a 45 degree angle towards the NORTH EAST corner from 0, in this case it is less then 1 so it is less steep then 45 degrees, how i remember is that i can plot a point using the numbers the the fraction in reverse and connect a line from 0,0 to that line
4,3 is a point that a line with this slope would cross, but not this line, because it does NOT start at 0,0 , instead it crosses the y-axis lower because we took some of b away, in this case -3, so the line moves down 3, not changing the slope
i hope this makes sence and you are able to use it in multiple problems like this, comment this if you have any questions

So first off the inequality sign has to be facing the 5 because that is the max amount of money he can spend on breakfast so we can immediately eliminate answer choices G and J
The reason the answer is not F is because your not adding b to 1.25
B is equal to the number of breakfasts Anthony can buy
Each breakfast cost $1.25 so it would be
5 is greater than or equal to 1.25b
Answer:
Step-by-step explanation:
b/c the breakfasts are $1.25 you would multiply how many he buys , by that cost, soo
5 ≥ 1.25 * b
so he can buy 4 breakfasts 1.25 * 4 = 5
this works out fine for the math. but, for one day .. no breakfast :(

Which relation is a function?
{(8, –5), (–5, 8), (–5, –8), (–8, 5)}
{(2, –3), (–3, 2), (2, 3), (–2, 3)}
{(–7, 6), (6, –7), (–7, 9), (10, 3)}
{(5, –4), (–4, 5), (–5, 4), (4, –5)}
Answer:
the last one
Step-by-step explanation:
when looking for the function we have to know that none of the x values can repeat
in the first one the x value -5 repeats twice so that cannot be the answer
in the second one the x value 2 repeats twice so that cant be the answer
in the third one the x value -7 repeats twice so that also cannot be the answer
in the last one each x value has a different y value or every input has a different output therefore this one is the right answer
hope this helps :D
The relation that is a function is: {(5, –4), (–4, 5), (–5, 4), (4, –5)}.
A relation is a function if each input (x-value) is associated with only one output (y-value).
Let's analyze each relation:
1. {(8, –5), (–5, 8), (–5, –8), (–8, 5)} - This relation is not a function because the input -5 is associated with two different outputs (8 and -8).
2. {(2, –3), (–3, 2), (2, 3), (–2, 3)} - This relation is not a function because the input 2 is associated with two different outputs (-3 and 3).
3. {(–7, 6), (6, –7), (–7, 9), (10, 3)} - This relation is not a function because the input -7 is associated with two different outputs (6 and 9).
4. {(5, –4), (–4, 5), (–5, 4), (4, –5)} - This relation is a function because each input value is associated with only one output value. For example, 5 is associated with -4, -4 is associated with 5, -5 is associated with 4, and 4 is associated with -5.
Therefore, the relation that is a function is: {(5, –4), (–4, 5), (–5, 4), (4, –5)}.
