Alex and his friends are studying for a geometry test and one of the main topics covered is parallel lines in a plane. They each write down what they think it means for two distinct lines in a plane to be parallel:Rachel writes, ''two distinct lines are parallel when they are both perpendicular to a third line.''



Alex writes, ''two distinct lines are parallel when they do not meet.''



Briana writes, ''two distinct lines are parallel when they have the same slope.''

Analyze each definition, indicating if it is mathematically correct and if it has any drawbacks.

Answer:

24 cars

Step-by-step explanation:

By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.

(AED 79.75)/(11 cars) = AED 7.25 / car

Now we divide AED 174 by AED 7.25/car to find the number of cars.

(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars

Answer: 24 cars

The solution to the following system is (2,1,0).

What is Algebra?

Algebra is defined as the study of mathematical symbols and in which letters and symbols are used to represent numbers.

We have,

3x+3y+6z=9    (i)

x+3y+2z=5    (ii)

3x+12y+12z=18  (iii)

To find the solution to the above give algebraic equations,

We have to find values of x,y,z.

So,

We will be putting z=0 in equation (i),

3x+3y+6(0)=9

3x+3y=9    (iv)

Now,

We will be putting z=0 in equation (ii),

x+3y+2(0)=5

x+3y=5  

x=5-3y    (v)

Using equation (iv) & (v),

We get,

3(5-3y) +3y=9

15-9y+3y=9

-6y=-6

y=1,

Now we have value of  y=1, putting this value in equation  (v),

x=5-3(1)

x=2,

Hence, we can say that option (2,1,0) is the correct answer.
