(4, -7)
Step-by-step explanation:
Maybe you want the solution to this system of equations.
About the easiest way to obtain it is to use a graphing calculator.
(x, y) = (4, -7)
_____
Additional comment
Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.
4x +(-2x +1) = 9
2x = 8 . . . . . . . . . . subtract 1 and simplify
x = 4
y = -2(4) +1 = -7 . . . use the first equation to find y

ANSWER:
[tex] \large\color{green}{ \tt{A. 1 / 10}}[/tex]
Solution Steps:
Least common multiple of 5 and 10 is 10. Convert 1/5 and 1/10 to fractions with denominator 10.
[tex]( \frac{2}{10} - \frac{1}{10} ) \times 3^{2} - \frac{4}{5} [/tex]
Since 2/10 and 1/10 have the same denominator, subtract them by subtracting their numerators.
[tex] \frac{2 - 1}{10} \times 3^{2} - \frac{4}{5} [/tex]
Subtract 1 from 2 to get 1.
[tex] \frac{1}{10} \times 3^{2} - \frac{4}{5} [/tex]
Calculate 3 to the power of 2 and get 9.
[tex] \frac{1}{10} \times 9 - \frac{4}{5} [/tex]
Multiply 1/10 and 9 to get 9/10.
[tex] \frac{9}{10} - \frac{4}{5} [/tex]
Least common multiple of 10 and 5 is 10. Convert 9/10 and 4/5 to fractions with denominator 10.
[tex] \frac{9}{10} - \frac{8}{10} [/tex]
Since 9/10 and 8/10 have the same denominator, subtract them by subtracting their numerators.
[tex] \frac{9 - 8}{10} [/tex]
Subtract 8 from 9 to get 1.

Answer:
2/3Step-by-step explanation:
If we want to find the slope, the most easiest way to find the slope is to use 'Rise/Run'. Two points are given, lets use those points and find the slope.
=> We see that the rise is 2. So 2 will be our numerator,
=> We can also see that the run is 3. So 3 will be our denominator.
What do we get?
We get 2/3 as our slope. Therefore, B is our answer. Hoped I helped.

4x2−12x+9=0
Answers
Answer:
4x2−12x+9=0
Step-by-step explanation:
The equation, 2x2+x+3=0, does not have a solution
The equation, x2+5x−3=0, equals -5/2+1/2√37 and -5/2+-1/2√37
The equation, x2−5x+4=0, equal 1 and 4
The equation, 4x2−12x+9=0, equals only 3/2

Answer:
x = 115°
Step-by-step explanation:
The two angles are vertical, so x = 115°
Vertical Angles:Vertical Angles are two angles formed by the intersection of two lines. Angles that are non-adjacent to each other are congruent in degrees.
We can see that 115° and x° are formed by the intersection of two lines, and they are non-adjacent (don't share a common side) which makes them congruent in degrees.
x = 115°

A smokestack deposits soot on the ground with a concentration inversely proportional to the square of the distance from the stack. With two smokestacks d miles apart, the concentration of the combined deposits on the line joining them, at a distance x from one stack, is given by:
[tex]S=\frac{c}{x^2} +\frac{k}{(d-x)^2}[/tex]
where c and k are positive constants which depend on the quantity of smoke each stack is emitting. If k=8c, find the point on the line joining the stacks where the concentration of the deposit is a minimum. xmin= ? miles
Answers
Answer:
d/3
Step-by-step explanation:
For k = 8c, the concentration is ...
S = c/x^2 + 8c/(d -x)^2
The minimum of the function will be found where its derivative is zero. The derivative with respect to x is ...
S' = -2c/x^3 +(-2)(8c)(-x)/(d -x)^3
We are interested in the value of x that makes this zero.
0 = -2c/x^3 +16c/(d -x)^3 . . . . . simplify slightly, set S'=0
0 = (-2(d -x)^3 +16x^3)/(x(d -x))^3 . . . . . combine terms, divide by c
0 = d^3 -3d^2x +3dx^2 -x^3 -8x^3 . . . . multiply by (x(d-x))^3/(-2)
9x^3 -3dx^2 +3d^2x -d^3 = 0 . . . . . simplified cubic
Factoring by grouping, we have ...
(9x^3 -3dx^2) +(3d^2x -d^3) = 0
3x^2(3x -d) +d^2(3x -d) = 0
(3x^2 +d^2)(3x -d) = 0
The solution will be found where the second of these factors is zero:
3x -d = 0
x = d/3
The concentration of the deposit is a minimum at x = d/3 miles.
_____
The graph shows the minimum is x = 1/3 when d = 1.
