Sprint to the finish the professional cyclist travels 380 meters in 20 seconds. At that rate how far does the cyclist travel in
kumpel [21]

Answer:

57 meters

Step-by-step explanation:

we know that

Sprint to the finish the professional cyclist travels 380 meters in 20 seconds

so

using proportion

Find out how far does the cyclist travel in 3 seconds

Let

x -----> the distance in meters

\frac{380}{20}\frac{m}{sec}=\frac{x}{3}\frac{m}{sec}\\\\x=380(3)/20\\\\x=57\ m

Stels [109]

Answer:

Sean can dive 275 feet after he takes 13 lessons.

Step-by-step explanation:

Since L means the number of lessons taken, we will have:

D = 20*13 + 15

D = 260 +15

D = 275

Do I have to solve this before graphing it and if so how do I go about it?
defon

Given the System of Equations:

\begin{cases}y=4x-1 \\  \\ y=x-4\end{cases}

The exercise asks for solving it graphically. Then, in this case, you need to graph both lines in order to determine the solution of the system.

In order to graph it, you can find the x-intercepts and the y-intercepts:

1. It is important to remember the Slope-Intercept Form of the equation of a line:

y=mx+b

Where "m" is the slope of the line and "b" is the intercept.

In this case, you can identify that the y-intercept of the first line is:

b_1=-1

And the y-intercept of the second line is:

b=-4

2. By definition, the value of "y" is zero when the line intersects the x-axis.

Then, you need to substitute the following value of "y" into each equation and then solve for "x", in order to find the x-intercept of each line:

y=0

- For the first line, you get:

\begin{gathered} y=4x-1 \\ 0=4x-1 \\ 1=4x \\  \\ \frac{1}{4}=x \\  \\ x_1=0.25 \end{gathered}

- For the second line, you get:

\begin{gathered} y=x-4 \\ 0=x-4 \\ 4=x \\ x_2=4 \end{gathered}

3. Now you know that the first line passes through these two points:

(0.25,0);(0,-1)

And the second line passes through these two points:

(4,0);(0,-4)

4. Knowing those points, you can graph the lines:

Notice that the line intersect each other at
