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°

Which function has the greater rate of change? What is that value?
Answer:
To find the rate of change you use the formula, Y2-Y1/X2-X1.
Function A:
You can substitute in any two points. The points I will use are (0,0) and (1,1).
1-0/1-0
1/1
1
The rate of change for Function A is 1.
Function B:
The points I will use are (2,1) and (4,2).
2-1/4-2
1/2
The rate of change for Function B is 1/2.
Since 1 is larger than 1/2, Function A has a larger rate of change. The value is 1.
Hope this helps! :)
HELP!!! IM CONFUSED
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.

9514 1404 393
Answer:
(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

determine if the lines are parallel, perpendicular, or neither. x - y = 4 and x + y = 9
Answer:
Perpendicular
Step-by-step explanation:
What I would do first is to rearrange these equations into the equation of a line formula: [tex]y=mx+c[/tex]
To do so, we isolate y:
x - y = 4 -> -y = -x+4 -> (multiply both sides by -1) y=x-4
x+y=9 -> y=-x+9
We know that in the formula y=mx + c, m stands for gradient of a line (The degree of steepness of the line), and we know that if there is no number before x it means that it is 1 or -1 (depending on the sign before x).
so that on y=x-4 the gradient is 1 and on y=-x+9 the gradient is -1.
We now can check if its parallel, perpendicular or neither with these equations:
m1 · m2 = -1 for perpendicular, m1 = m2 for parallel,(where m = gradient)
we plug the values of the two gradients into the first equation
(m1 · m2 = -1) and it fits: 1 x -1 = -1
If we plug the same values into the second equation (m1 = m2), we can check that 1 ≠ -1
In conclusion, we can check that these lines are perpendicular to each other.
Which of the following equations has one real solution?
2x2+x+3=0
x2+5x−3=0
x2−5x+4=0
4x2−12x+9=0
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
Hope this Helps
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
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.
