Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answers
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

Solve the system by elimination
2x – y=1
x + 3y – 4= 0
Answers
The value of x and y for the given equation by elimination method are 1 and 1 respectively.
Elimination method for solving the system of equations;The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the given question
We have two equations
[tex]2x -y =1...(1)[/tex]
[tex]x+3y-4=0...(2)[/tex]
Multiply equation (1) both the sides by 3
[tex]6x - 3y =3...(3)[/tex]
Adding equation (2) and (3)
[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]
Substitute
x =1, in either 2x -y =1 or x + 3y -4 =0
2(1) - y =1
⇒ -y = 1 -2
⇒ -y = -1
⇒ y =1
Hence, the value of x and y is 1 and 1 respectively.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"
For given question,

Let [tex](x_1,y_1)=(600,0),(x_2,y_2)=(75,0)[/tex]
The slope of the line would be,
[tex]\Rightarrow m=\frac{y_2-y_1}{x_2-x_1}\\\\\Rightarrow m=\frac{0-600}{75-0}\\\\\Rightarrow m =\frac{-600}{75}\\\\ \Rightarrow m = -8[/tex]

Write a rational function with an x-intercept at (-9,0), a vertical asymptote at x=3, and a hole located at (1,-5). Then, identify the horizontal asymptote.
Answers
Answer:
The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]
The horizontal asymptote occur at y = 1
Step-by-step explanation:
Given that the function has an x-intercept at (-9, 0), we have;
(x + 9) is a factor of the function
Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)
With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5
The general form of the function can be presented as follows;
f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)
Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1
The horizontal asymptote occur at y = 1

The lateral surface area of the triangular prism is
Explanation:
The side lengths of the base of the triangular prism are 5 meters, 8 meters, and 10 meters.
It is given that the height of the prism is 16.5 meters.
To determine the lateral surface area of the prism, let us use the formula
LSA = (a + b + c)h
where a, b,c are the side lengths of the base of the triangular prism and h is the height of the prism.
Here: a = 5, b = 10,c = 8 and: h = 16.5
Substituting these values in the formula, we have,
LSA = (5 + 10 + 8) 16.5
Simplifying, we get,
LSA = (23) 16.5
Multiplying, we get,
LSA = 379.5
Thus, the lateral surface area of the triangular prism is,
379.5sq. units
