No they would be intersecting. x=-1 is a vertical line down the x axis on -1. y=2 is a horizontal line at 2 on the y axis.

Hi! Your problem will be explained in the explanation section.

Furthermore, your answer is No, the given lines are not parallel.

Why? See below! Questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Hi there! Today I will be explaining these things which may benefit you.

  • Parallel Line
  • Perpendicular Line
  • Horizontal and Vertical Line

You might have known or heard these lines somewhere. <em>But what are they?</em>

<u>Parallel</u>

Parallel Lines are lines that do not intercept each others. They are same lines except they have distance. I think you might be confusing if I keep explaining. Let's look at an attachment instead. Please see <u>the first attachment</u> for how do parallel lines look like.

<u>Perpendicular</u>

Perpendicular Lines are lines that intercept each others. Both lines intercepting each others create a right angle around the interception. See <u>the second attachment</u> for how do perpendicular lines look like.

Next things are going to be main topic for our problem. <em>What is the difference between graph of x = -1 and y = 2?</em>

In the coordinate plane, graph of x-coordinate would be a straight vertical line because x = -1 isn't given any ranges. Therefore, x = -1 would have range as real number.

Similar to y = 2. y = 2 isn't given any domains. Therefore, y = 2 would have domain as real number and have a horizontal line graph.

What is the y-intercept of the function, represented by the table of values
AleksandrR [38]

Answer:

9

Step-by-step explanation:

The table is given below

\left|\begin{array}{c|cc}x&y\\--&--\\-2&15\\1&6\\2&3\\4&-3\\7&-12\end{array}\right|

We can see that the table represents a linear function since by checking its slope.

Using:

  1. Points (-2,15) and (1,6)
  2. Points (1,6) and (2,3)

Slope =\dfrac{6-15}{1-(-2)} =\dfrac{3-6}{2-1}=-3

Therefore, the values represent a linear function.

A linear equation is of the form y=mx+b

Therefore:

y=-3x+b

Using the points (7,-12)

-12=-3(7)+b\\-12=-21+b\\b=-12+21\\b=9

Therefore, the y-intercept of the function, represented by the table of values is 9.

Answer: -15yx^2

Step-by-step explanation:

-12x^2 * y -3x^2 * y=

-12(x^2 * y)-3(x^2 * y)=

(-12-3)(x^2 * y)=

-15x^2 * y=-15yx^2

What is the range of F(x)=72x-x^2
Marianna [84]

Answer:

Range of F(x) = (-∞ ,72).

Step-by-step explanation:

Range of the function F(x) means the set of values which are taken by the function along its domain.

F(x) = 72 - x^{2}

Since coefficient of x^{2} is negative on the right side ,

Maximum value of F(x) will come at x = 0.

Which is, F(0) = 72.

Now, as x increases , F(x) decreases , when x will reach infinity ,

F(x) will be reaching negative of infinity .

Thus, F(x) is ranging from -∞ to 72 .

Range of F(x) = (-∞ ,72).
