Answer:

R(x) = 2.25x + 4.49

Step-by-step explanation:

Equation form: R(x) = mx + b

m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.

b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.

Since we know the value of m and b, we can write the equation:

R(x) = 2.25x + 4.49

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

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!

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).

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.

Answer:

It's C, g(x) = (1/2)^x

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.

Answer:

  y = -4/5x +3/5

Step-by-step explanation:

The 2-point form of the equation for a line can be useful.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (3 -(-1))/(-3 -2)(x -2) -1

  y = 4/(-5)(x -2) -1

  y = -4/5x +8/5 -1

  y = -4/5x +3/5

it is equal to zero

A video of a drumming session.

Answer:

D. A video of a drumming session

Explanation:

A presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.

Basically, any speaker who wishes to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation and using a multimedia resource.

In this scenario, Diego has written a feature story about a drumming circle. Thus, what he should include in his visual presentation to interest the audience in the drumming experience is a video of a drumming session.

Generally, they say action speaks louder than words, and people often believe what they can see.

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.

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

Supplier A has the lowest average cost per ball.
