The Whittman family took a car trip. They traveled 1/5 the distance from San Antonio to Austin on Monday and 2/9 the distance on Tuesday. What fraction of the distance between San Antonio and Austin did the Whittman family travel on Monday and Tuesday?
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

Write the equation of the line from the table below.
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]

Describe how you could use a graphing calculator to estimate the value of x when f(x) = 8(1.25)^x equals 15.
Answer: here
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
What is exponential graph?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.
How to read graph of exponential functionsThe 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

The purchase price of a camcorder is $588. What is the total price if the sales tax rate is 4.5%?
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

What is the asymptote of the graph of an exponential growth or exponential decay function? Explain your reasoning.
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.

b) Proportional because the unit rates are $1.80 per bottle.
c) Nonproportional because the bottles have different unit rates.
d) Nonproportional because one grocery store has more bottles.

B. Connect the arrows with a straight line
C. Line up the baseline on the protractor with the ray
D. Draw arrows on both ends to make them rays
Answer:
B

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
