[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]
Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.
Multiply all whole equation by 6.
[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]
We should get like this. Then move 2x to subtract.
[tex]2x^2-2x-3=0[/tex]
Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.
But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.
[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]
This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.
[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]
Therefore, the answer is x = (1±√7)/2

Answer:
∠x = 30°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends. Angle BAC is half the measure of arc BC.
Arc ABC is a semicircle, so measures 180°. Of that, arc AB is 120°, so the remainder, 180° -120° = 60° is the measure of arc AB.
Angle x is half that, or 60°/2 = 30°.
The measure of angle x is 30°.

6. slope = -1/2
7. slope = 3
8. slope = -1/10
9. slope = 1/2
10. slope = -1/2
Explanation :
I won't explain every question because that'll take forever but I can explain one step by step.
An example is number 5
You have the points, ( -4 , 5 ) ( 1 , 0 )
You need to use the SLOPE FORMULA
So first put an x1 and y1 below the points -4 and 5.
then put x2 and y2 below the points 1 and 0
the slope formula is m = y2-y1/x2-x1
plug in the numbers which will look like
0-5/1+4
It's plus 4 instead of -4 because a negative and negatives gives you a postivie
Simplify and you get m = -1
In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?
A. 32
B. -32
C. 5
D. 24
Answers
Answer:
D. 24
Step-by-step explanation:
Plug in -14 to the equation:
f(x) = 2x - 4(x + 1)
f(-14) = 2(-14) - 4(-14 + 1)
Simplify:
f(-14) = -28 - 4(-13)
f(-14) = -28 + 52
f(-14) = 24
So, D is the correct answer.

Answers
Answer:
Table shown below
Step-by-step explanation:
Linear Modeling
It consists of finding and using the equation of a line to represent the behavior of a real situation in numerical terms.
We are given the model of the charges for a satellite radio company that charges a fixed fee of $36 for installation and a variable fee of $42 per month for use.
The model is written as:
C(m) = 36 + 42m
Where m is the number of months.
For m=1:
C(1) = 36 + 42(1)=$78
For m=2:
C(2) = 36 + 42(2)=$120
For m=3:
C(3) = 36 + 42(3)=$162
For m=4:
C(4) = 36 + 42(4)=$204
For m=5:
C(5) = 36 + 42(5)=$246
The calculations are resumed in the table shown below.

Answers
Answer:
The friends split the bill at 15.32$
Step-by-step explanation:
So to find how much each paid you would take the bill total and divide it by the amount of people in this case three
And for the equation it would be 45.96/3=15.32$
The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
Given that the dinner for Lorenzo and his 3 friends costs $45.96.
To determine how much each paid would take the bill total
Therefore, we will divide it by the number of people in this case three
3x = 45.96
x = 45.96/3
x = 15.32$
And for the equation would be; 3x = 45.96
