to determine whether a graph is also a function, Shayla declares that the y-axis is a vertical line and counts the number of tim

es the graph intersects the y-axis. If the graph has exactly one y-intercept, shayla concludes that the graph shows a function. In all other cases, she declares that it is not a function. Is she applying the vertical line test correctly

Answer:

Shayla is not applying the vertical line test correctly.

Step-by-step explanation:

The vertical line test is useful to determine whether the provided curve is a graph of function or not.

Vertical line test: If we draw a vertical line anywhere on xy plane and the vertical line intersect the graph more than once, then the graph is not a function.

Consider the figure 1:

The vertical lines intersect the graph exactly at one spot. it doesn't matter where we drop the vertical line.

Now consider the figure 2:

Here, the graph has exactly one y-intercept, but it doesn't follow the vertical line test as the graph hits the vertical line in two spots.

Therefore, she is not applying the vertical line test correctly.

Shayla is not applying the vertical line test correctly because it may be a specific function that only intersects the y-axis once but may intercept other values of x multiple times, in order to correctly apply the vertical line test to determine if a graph shows a function or not you must test for multiple points at all x-values of a graph.

Find the equation of the line that passes thru (-1,-5) and is parallel to 3x+y=-5. Show work.
sertanlavr [38]

Answer:

y=-3x-8

Step-by-step explanation:

slope-intercept form:

y=mx+b

Start with the given equation, and to find the slope, convert it to slope-intercept form by solving for y.

3x+y=-5

In this case, all you need to do is subtract 3x from both sides.

y=-3x-5

Here, the slope is -3. The slope of a parallel line will also be -3.

Now, we have 3 known variables. We have the slope and the x and y of a known point. Use those 3 knowns to solve for the 1 unknown, the y-intercept.

y=mx+b\\-5=(-3)(-1)+b\\-5=3+b\\-8=b\\b=-8

Finally, with the slope and the y-intercept, you can write the equation of the line:

y=-3x-8

A certain piece of copper wire is determined
Sati [7]

Answer:

14

Step-by-step explanation:

mass of 100 centimeters of copper wire is 2.00

so, mass of 1 centimeter of copper wire will be \frac{2}{100}

hence, 14 centimeters of copper wire will provide .28 copper
