Answer:

The given point is not on the line.

Step-by-step explanation:

3 represents x

3 represents y

1. Plug in the numbers to x and y variables

y= [tex]-\frac{2}{3}[/tex] x + 1

3= [tex]-\frac{2}{3}[/tex] (3) + 1

2. Cancel out the greatest common factor

3=-2+1

3. Solve

3=-1

If the numbers do not equal each other, then the equality is false.

Step-by-step explanation: 1. Plug in the numbers to x and y variablesy=  x + 13=  (3) + 1

2. Cancel out the greatest common factor 3=-2+13. Solve3=-1

Step-by-step explanation:

8 (1.25) x = 15 8(1.25)^x=15 8 (1.25) x = 15. There are two ways: by using a graph or by using a table. Here, I will use a graph since using a table was already discussed

Using a graphing calculator the value of x is sought by tracing from point 15 up to the curve, at the point of intersection with the curve then trace to the corresponding y direction. At 15 the f(x) is about 227

A curve that depicts an exponential function is known as an exponential graph.

The curve have a horizontal asymptote and either an increasing slope or a decreasing slope. this is to say that the curve begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates. It may or may not cut the x-axis, but it always cuts the y-axis at some point.

An exponential graph will almost always have a y-intercept but not necessarily an x-intercept.

The corresponding value of each point is located by tracing it using imaginary line

From the x axis at 15  draw an imaginary line up to the curve. the point of intersection of the line and the curve is traced to the y axis. The value at that point gives the required the solution

The graph is attached

[tex]y = \boxed{5}x + \boxed{9}[/tex]

Step-by-step explanation:

Hello,

The sales tax for a camcorder that costs $588 would be $588 * 0.045 = $26.46. Therefore, the total price would be $588 + $26.46 = $614.46.

The answer is: $614.46

Let's consider an exponential decay function.

As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]

Here is a table of selected values:

[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]

As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.

Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.

See the graph below. I used Desmos to create the graph.

5x4=20

Answer:

Tamara will receive 20 hours of paid vacation time if she works 50 days.

Hope this helps!

Step-by-step explanation:

10 days = 4 hours

10*( 5 ) = 4*( 5 )

50 days = 20 hours

to get the equation of any straight line, we simply need two points off of it, let's use those two in the picture below.

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{9000})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{3000}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3000}-\stackrel{y1}{9000}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}} \implies \cfrac{ -6000 }{ 2 } \implies - 3000[/tex]

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9000}=\stackrel{m}{- 3000}(x-\stackrel{x_1}{2}) \\\\\\ y-9000=-3000x+6000\implies {\Large \begin{array}{llll} y=-3000x+15000 \end{array}}[/tex]

Answer: 19/45

Step-by-step explanation:

1/5 + 2/9 = ?

Find the least common denominator.

which in this case is 45

5 times 9 = 45

Multiply 1/5 by 9/9

Multiply 2/9 by 5/5

9/45 + 10/45= 19/45

Answer:

y = 2x + 4/5

Step-by-step explanation:

Slope-intercept form is written as:

y = mx + b, where (x,y) is a point on the line, m is the slope, and b is the y-intercept.

To get 10x - 5y = -4 into the form y = mx + b, you'll first want to get y by itself. You can start by subtracting 10x from both sides.

10x - 5y = -4

-5y = -10x - 4

As you can see, y still has a coefficient of -5 in front of it, so we'll have to divide the entire equation by -5 (you have to divide each term individually).

-5y = -10x - 4

y = 2x + 4/5
