When y=-2, what kind of line does it have horizontal or vertical

Mathematics
1 answer:
Rashid [163]3 years ago
8 0

Answer: Horizontal

Step-by-step explanation: The equation <em>y = -2</em> can be thought of as y = 0x - 2. So our line has a slope of 0 and a y-intercept of -2.

To graph it, we start with the y-intercept, down 2 units on the y-axis. Now, if the slope of a line is 0, then the line must be flat or horizontal.

So we just draw a horizontal line through the y-intercept of -2.

In fact, when the equation of any line reads y = a number, it's graph will always be a horizontal line. For example, y = 3, y = -10, y = -8 and so on.

Two angles form a linear pair. The measure of one angle is 13 the measure of the other angle. Find the measure of each angle.
QveST [7]

Your question is not complete so there are two answers:

<h3>1. </h3>

The measure of one angle is 13 <u>times</u> the measure of the other angle.

Answer:

<h3>         One angle is 167.14° and the other is 12.86° </h3>

Step-by-step explanation:

Two angles of a linear pair create a straight angle therefore they add to 180°

x°     - the other angle

(13x)°  - one angle

x + 13x = 180

   14x = 180

  ÷14      ÷14

   x ≈ 12.86

13x = 13•12.86 = 167.14

Checking:  12.96+167.14 = 180

<h3 /><h3>2. </h3>

The measure of one angle is 13 <u>more than</u> the measure of the other angle.

Answer:

<h3>         One angle is 96.5° and the other is 83.5° </h3>

Step-by-step explanation:

Two angles of a linear pair create a straight angle therefore they add to 180°

x°     - the other angle

(x+13)°  - one angle

x + x + 13 = 180

       -13        -13

    2x  =  167

    ÷14      ÷14

     x ≈ 83.5

x+13 = 83.5 + 13 = 96.5

Checking:  83.5+96.5 = 180

A model Nasar race car lists 79.99 with a trade discount of 40% . What is the net price of the car?
slava [35]

Hello!

79.99 equals 100%, or in other words, 79.99 = 1.

To find the net price, you'll need to find the discount, multiplying the total by 40% (or 0.4):

\mathrm{79.99\cdot0.4 \approxeq 31.99}

Now, just subtract the initial price by the discount:

\mathrm{79.99-31.99\approxeq 48}

So, the net price of the car is approximately 48.00.

Hope this helps!
