The simplified equation of [tex]\frac{x^{2}-9 }{3x^{2} +8x-3}+\frac{x-3}{x+2}[/tex] is [tex]\frac{(x-3)(4x+1)}{(3x-1)(x+2)}[/tex]
What is Simplification?Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler. Therefore,
[tex]\frac{x^{2}-9 }{3x^{2} +8x-3}+\frac{x-3}{x+2}[/tex]
3x² + 8x - 3 = (3x - 1)(x + 3)
x² - 9 = (x - 3)(x + 3)
Therefore,
[tex]\frac{(x-3)(x+3)}{(3x-1)(x+3)} +\frac{x-3}{x+2} =\frac{(x+2)(x-3)(x+3)+(x-3)(x+3)(3x-1)}{(3x-1)(x+3)(x+2)}[/tex]
Therefore,
[tex]\frac{(x+2)(x-3)(x+3)+(x-3)(x+3)(3x-1)}{(3x-1)(x+3)(x+2)}=\frac{((x+3)(x-3)((x+2)+(3x-1)))}{(3x-1)(x+3)(x+2)}[/tex]
[tex]\frac{((x+3)(x-3)((x+2)+(3x-1)))}{(3x-1)(x+3)(x+2)}=\frac{(x-3)((x+2)+(3x-1))}{(3x-1)(x+2))}[/tex]
Therefore,
[tex]\frac{(x-3)((x+2)+(3x-1))}{(3x-1)(x+2))} = \frac{(x-3)(x+2+3x-1)}{(3x-1)(x+2)}[/tex]
[tex]\frac{(x-3)(x+2+3x-1)}{(3x-1)(x+2)}=\frac{(x-3)(4x+1)}{(3x-1)(x+2)}[/tex]

4x-3 = 2x + 13
Someone help plz
Answers
4x-3=2x+13
All you have do is subtract 2x from 4x which is 2x
So now the equation will become
2x-3=13
Minus 3 on both sides So 2x is left over
2x=16
X=8
Answer:
One solution
Step-by-step explanation:
4x - 3 = 2x + 13
4x − 3 − 2x = 2x + 13 − 2x (subtract 2x from both sides)
2x - 3 = 13
2x − 3 + 3 = 13 + 3 (add 3 to both sides)
2x = 16
2x/2 = 16/2 (dividing 2 from both sides)
x = 8

Let g be a differentiable function with g(-1)=5 and g'(-1)=2. What is the value of the approximation of g(-0.9) using the function's local linear approximation at x= -1?
Options: 5.1, 5.2, 5.3, or 5.4
Answers
Answer:
5.2
Step-by-step explanation:
g(x) = mx +b
g'(x) = m = 2 for all x
g(-1) = 2(-1) + b = 5
-2 + b = 5
b = 7
So, g(x) = 2x + 7
Therefore g(-.9) = 2(-.9) + 7
= -1.8 + 7 = 5.2
The value of g(-0.9) is equal to 5.2.
What is a Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
As per the given data:
g(x) is a differentiable function.
We have to use the function's local linear approximation at x = -1.
g(-1) = 5
g'(-1) = 2
As We have to use the function's local linear approximation:
Let assume, g(x) = mx + b
Differentiating both sides,
g'(x) = m
∴ g'(-1) = 2 = m
m = 2
g(x) = 2x + b ...(i)
g(-1) = 5
Using in eq (i)
5 = -2 + b
b = 7
g(x) = 2x + 7
Let's substitute x = -0.9 to find out the answer.
g(-0.9) = 2(-0.9) + 7
= 7 - 1.8 = 5.2
The value of g(-0.9) is equal to 5.2.
Hence, The value of g(-0.9) is equal to 5.2.

In golf, the lower your score the better. Negative scores are best of all. Teri scored +1 on each of the first three holes at a nine-hole miniature golf course. Her goal is a total score of -9 or better after she has completed the final six holes. Let h represent the score Teri must avereage on each of the last six holes in order to meet her goal. Write a 2-step inequality you can use to find h
Answers
Answer:
h ≤ - 2
Step-by-step explanation:
Given :
Score on each of first 3 holes = +1
Total number of holes = 9
Target score - 9 or better ≤ - 9
Number of holes left = 9-3 = 6
h = average score on each of last 6 holes to meet target score ;
3 * (+1) + (number of holes left * average score) = target score
3 + (6 * h) ≤-9
3 + 6h ≤ - 9
6h ≤ - 9 - 3
6h ≤ - 12
h ≤ - 2

Step-by-step explanation:
Given
Perpendicular to: y = x - 7
Passes through (-2,-6)
Required
Find the equation
An equation has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
In [tex]y = x - 7[/tex]
[tex]m = 1[/tex]
Since the required equation is perpendicular to [tex]y = x - 7[/tex], then the relationship between their slopes is:
[tex]m_2 = -\frac{1}{m}[/tex]
Substitute 1 for m
[tex]m_2 = -\frac{1}{1}[/tex]
[tex]m_2 = -1[/tex]
The equation is then calculated using:
[tex]y -y_1 = m(x - x_1)[/tex]
Where
[tex]m_2 = -1[/tex]
[tex](x_1,y_1) = (-2,-6)[/tex]
So, we have:
[tex]y - (-6) = -1(x - (-2))[/tex]
[tex]y +6 = -1(x +2)[/tex]
[tex]y +6 = -(x +2)[/tex]

Answer:
v=1/3pie r^2 h
150pie=1/3 pie 5^2 h
450 pie/ pie=25h
h=18
Answer:
18 units
Step-by-step explanation:
You have that V = 1/3 * pi * r^2 * h and V = 150 * pi and r = 5, so you substitute those second two values into the first equation.
150pi = 1/3 * pi * 5^2 * h
simplifying the left side,
150pi = 25/3 * pi * h
divide both sides by pi
150 = 25/3 * h
divide both sides by 25/3
h = 18

Find the inequality
Answers
Answer:
y > x/2 + 2
Step-by-step explanation:
Firstly, we need the to find the equation of the line normally
the general form is;
y = mx + b
where m is slope and b is the y-intercept
From the graph, the y-intercept is 2
so we have the equation as;
y = mx + 2
We can find a point to substitute so as to get the slope;
we use the point (2,3)
3 = 2m + 2
2m = 3-2
2m = 1
m = 1/2
The equation of the line is;
y = x/2 + 2
Now, we can see we have a breaking line indicative of a non-equal to inequality
Also, the top is shaded meaning the points we need are above the line indicating a greater than
So, the inequality is;
y > x/2 + 2
