Answer:
k = 3
Step-by-step explanation:
f(x) = 112 - kx ------------------(I)
f(-3) = 121
In equation (I) substitute x = -3
112 - k*(-3) = 121
112 + 3k = 121
3k = 121 - 112
3k = 9
k = 9/3
k = 3

This is a horizontal reflection of y = 2^x
across the y axis.
Step-by-step explanation:
Using the process of elimination, you can spot this answer by applying what is logical about the transformations of an exponential function.
The transformations of a standard exponential function can be given by:
ab^(1/c(x-h))+k
First note that A must be incorrect because -2^x would be a reflection across the x axis which would not match the function g because a reflection across the x axis would cause the exponential growth or decay value b to become a reciprocal and -2 is not a reciprocal of 2.

What is y=2/3x-5 in standard form?
9514 1404 393
Answer:
2x -3y = 15
Step-by-step explanation:
Add 5-y to put the variables on the same side of the equal sign. Then multiply by 3 to clear the fraction.
5 = 2/3x -y
15 = 2x -3y
2x -3y = 15 . . . . standard form

Step-by-step explanation:
Find all points (x, y) where the functions f(x), g(x), h(x) have the same value: f(x) = 2^(x−5) + 3, g(x) = 2x − 5, h(x) = 8/x + 10
very fast please
Answer:
The point where all three lines meet is (8, 11)
Step-by-step explanation:
The given functions are;
f(x) = x²⁽ˣ ⁻ ⁵⁾ + 3
g(x) = 2·x - 5
h(x) = 8/x + 10
Equating the simpler functions g(x) to h(x) to find the points of the same value gives;
2·x - 5 = 8/x + 10
2·x - 15 = 8/x
2·x² - 15·x = 8
2·x² - 15·x - 8 = 0
With the aid of an online application, we have;
(2·x + 1)(x - 8) = 0
x = -1/2, or x = 8
The y-values at the point of intersection, is given as follows;
g(x) = 2·x - 5 = 2×(-1/2) - 5 = -6 or g(x) = 2·x - 5 = 2×(8) - 5 = 11
The points where g(x) and h(x) meet are (-1/2, -6) and (8, 11)
To check where the point of intersection of the two functions g(x) ang h(x) meet f(x), we have;
At x = -1/2, f(x) = [tex]2^{(0.5 - 5)} + 3[/tex] = 3.0442
At x = -1/2, f(x) = 2⁽⁸⁻⁵⁾ + 3 = 8 + 3 = 11
Therefore, the point where all three lines meet = (8, 11).

Answer:
[tex]\textbf{D.}\quad g(x)=\sqrt{x+6}+4[/tex]
Step-by-step explanation:
A lot of math is about matching patterns.
For example, ...
g(x) = f(x -h) +k
means g(x) is the function f(x) translated right by h units and up by k units. This will be true for any expression of f(x).
__
In this problem, f(x) = √x. We want to translate it left 6 units (h=-6)*, and up 4 units (k=4).
The notation above means that we will replace x with (x-h) = x+6. and we will add k = 4 to the result.
f(x) = √x
g(x) = f(x+6) +4
g(x) = √(x+6) +4 . . . . . . matches choice D
_____
* Left is the opposite of right, so left 6 units is the opposite of right 6 units. h=6 for right 6 units, so h=-6 for left 6 units. Then x-h = x-(-6) = x+6.
__
Comment on the graph
I find it useful to see a picture with these things. In the attached graphing calculator output, the blue curve is left 6 and up 4 from the red curve. The blue curve is g(x); the red one is f(x).

Two competing sports equipment suppliers sell footballs at different prices. Supplier A charges $85 in shipping, and charges $2.59 per football. Supplier B charges $50 shipped, and charges $4.29 per football. A school wants to buy 40 balls.
What is the equation for supplier A? Answer:
What is the equation for supplier B? Answer:
Which supplier has the lowest average cost per ball? Answer:
The equation for supplier A and supplier B will be y = 2.59x + 85 and y = 4.29x + 50, respectively. Supplier A has the lowest average cost per ball.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Footballs are sold at varying prices by two rival sports equipment vendors. Supplier A costs $85 for shipping and $2.59 for each football. Supplier B costs $50 for shipping and $4.29 per football. A school wants to purchase 40 balls.
Let x be the number of the football and y be the total cost.
The equation for supplier A will be given as,
y = 2.59x + 85
At x = 40, the value of 'y' is given as,
y = 2.59 × 40 + 85
y = $188.6
The equation for supplier B will be given as,
y = 4.29x + 50
At x = 40, the value of 'y' is given as,
y = 4.29 × 40 + 50
y = $221.6

Leading term of -20(x - 2)^15 (4-x)^11
9514 1404 393
Answer:
20x^26
Step-by-step explanation:
The leading term is the one with the highest degree.
In the expansion of (x-2)^15, that will be x^15.
In the expansion of (4-x)^11, that will be (-x)^11 = -x^11.
So, the leading term of the product is ...
(-20)(x^15)(-x^11) = 20x^26
__
In the attached, terms are listed in order of increasing degree, so the "leading" term appears last.
============================================
Work Shown:
The leading term for (x-2)^15 is x^15
The leading term for (4-x)^11 is -x^11
Multiply the outer value -20 with each of those leading terms to get
-20*x^15*(-x^11)
20x^(15+11)
20x^26
which is the leading term of -20(x - 2)^15 (4-x)^11

Graph -2x + y = 8 please help
Answer
Graph shown below
Step-by-step explanation:
In order to graph something, you need to know the slope and why intercept of the line. One way to do this is to put the equation into slope-intercept form. Slope intercept form is y = mx + b, where m = slope and b = your y-intercept. One way to put the equation -2x = y = 8 into the slope-intercept form is to add the -2x to the other side of the equation. Then you will get y = 8 + 2x. Now, because of the commutative property of addition, you can write the equation as y = 2x + 8. Then graph the equation. Since you know that 8 is a y intercept. You can graph the first point of your line. After, you just use slope (which is 2/1) and graph other points on a graph to get you your line. Hope this helps!

The general form of an parabola is 4y2+40y+3x+103=0. What is the standard form of the parabola?
9514 1404 393
Answer:
x = -4/3y² -40/3y -103/3
x = -4/3(y +5)² -1
Step-by-step explanation:
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
_____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.
