What is the equation of the horizontal line through (-7,-3)(−7,−3)?

Mathematics
1 answer:
Sholpan [36]3 years ago
3 0

Answer:

y = -3

Step-by-step explanation:

This is because horizontal lines have a slope of 0. And for horizontal lines, the equation of the line is y = b. So, b is the y-intercept and the y intercept is -3 so that is the equation of the line.

Answer:

25

Step-by-step explanation:

Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -x + 1

y = 4x - 14

<u>Step 2: Rewrite Systems</u>

y = 4x - 14

  1. Multiply everything by -1:                    -y = -4x + 14

<u>Step 3: Redefine Systems</u>

y = -x + 1

-y = -4x + 14

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine equations:                    0 = -5x + 15
  2. Isolate <em>x</em> term:                               -15 = -5x
  3. Isolate <em>x</em>:                                       3 = x
  4. Rewrite:                                        x = 3

<u>Step 5: Check</u>

  1. Define equation:                    y = -x + 1
  2. Substitute in <em>x</em>:                       y = -3 + 1
  3. Add:                                        y = -2

How is the theoretical probability of an event​ computed?
Sedaia [141]

The theoretical probability of an event​ computed as

Theoretical Probability = \frac{ Number of desired outcomes}{ Number of possible outcomes.} This is further explained below.

<h3>What is theoretical probability?</h3>

Generally, The theoretical probability formula is the ratio of the number of successful outcomes to the total number of possible possibilities. We may write this formula out as follows:

In conclusion, the theoretical probability is mathematically given as

Theoretical Probability = \frac{ Number of desired outcomes}{ Number of possible outcomes.}
