Mathematics
1 answer:
xeze [42]2 years ago
3 0

Answer:

x = 6 or x = -5

Step-by-step explanation:

x^2 - 30 = x

x^2 - x - 30 = 0

(x - 6)(x + 5) = 0

x - 6 = 0 or x + 5 = 0

x = 6 or x = -5

A school plays a series of 6 soccer matches. For each match there are 3 possibilities: a win, a draw or a loss. How
Sphinxa [80]

Answer:

There are 729 possible results are there for the series

Step-by-step explanation:

If we have n trials, each with m possible outcomes, the total number of possible outcomes is:

T = m^{n}

In this question:

6 games(trials), so n = 6.

Each with three possible outcomes, so m = 3

Then:

T = 3^{6} = 729

There are 729 possible results are there for the series

For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the y-axis? Circle
zaharov [31]

Answer:

a) Not parallel to y-axis

b) Not parallel to y-axis

c) Parallel to y-axis

Step-by-step explanation:

The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.

The equation of line: (y-y_1) = \frac{y_2 - y_1}{x_2 - x_1}(x-x_1)

a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.

It is parallel to x-axis.  Another two points that can lie on this line are : (5,12) and (\frac{9}{2},12).

b) The line joining the points (\frac{3}{5}, \frac{13}{5}), (\frac{1}{5} ,\frac{8}{5}) is not parallel to y-axis.

Equation of line: 5y - 7.5x = 5.5

Another points that could be lie on this line are (0.6,2) and (0.25,1.475)

c) The line joining the points (0.8, 1.9), (0.8,2.3) is parallel to y-axis because points have the same x-coordinate.

Another points that could be lie on this line are (0.8,2) and (0.8,2.1)
