Answer:

Inconsistent

Step-by-step explanation:

A system of equation is said to be inconsistent if the lines are parallel or the system of equations have no solution.

From the given graphs of lines, we can say that the lines are parallel to each other. Hence, the graphs never intersect.

Since, the lines are parallel hence, we can say that there would be no solution for the system of equations.

Therefore, the system is inconsistent.

Hence, third option is the correct option.

To find the percentage,we need to form a fraction first:

The nominator would be: the students who have not blue eye and were not wearing orange at the same time (50)

The denominator: students with not blue eyes (20)

Hence we can form the fraction: 20/50

To find the percentage, we can multiply the fraction by 100%:

20/50x100%

=2/5 x 100%

= 200/5 %

= 40%

Therefore the answer is 40%.

Hope it helps!

Find the parallel and perpendicular slope of a line if linear equation is 7y=20(x-3) Slope (Parallel) is ____ Slope (Perpendicul

yKpoI14uk [10]

Answer:

The parallel line has slope $\frac{20}{7}$

The perpendicular line has slope $-\frac{7}{20}$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

Parallel lines:

Parallel lines have the same slope.

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

In this question:

We have the following line:

$7y = 20(x-3)$

Placing it in the general format

$7y = 20x - 60$

$y = \frac{20x}{7} - \frac{60}{7}$

So this line has slope $\frac{20}{7}$

Parallel line:

Same slope, so the parallel line has slope $\frac{20}{7}$

Perpendicular line:

Multiplication of the slopes is -1. So

$\frac{20m}{7} = -1$

$20m = -7$

$m = -\frac{7}{20}$

The perpendicular line has slope $-\frac{7}{20}$

Oxana [17]

The ratio ...

... seniors : juniors = 3 : 2

can be multiplied by 7 to get

... = 21 : 14

indicating there are 14 juniors for the 21 seniors in the choir.
