Coretta wants to create a system of equations so that the system has only one solution. which of these can coretta do? check all that apply. create a pair of equivalent equations. create a pair of lines in which one line lies directly on top of the other. create a pair of equations with different slopes. create a pair of lines that will always stay the same distance apart. create a pair of lines that intersect at only one point.

option 3 and 5 are correct i.e.

3) Create a pair of equations with different slopes.

5) Create a pair of lines that intersect at only one point.

Step-by-step explanation:

Since for a system of equations to have a unique solution we must have the following properties:

1)

if we will create  a pair of equivalent equations then we can't get a unique value of x and y we will get that either x is depending on y or y is depending on x i.e. we will have a variable equation.

Hence option 1) is not correct.

2)

Create a pair of lines in which one line lies directly on top of the other.

If such a case happens than also we have same equation for both the lines and like 1) we do not get a unique solution.

Hence option 2) is not correct.

3)

Create a pair of equations with different slopes.

such a case will help us to get a unique solution since we will be able to solve the system of equations by means of method of elimination.

Hence, option 3) is correct.

4)

Create a pair of lines that will always stay the same distance apart.

If such a case will happen than that means the two lines are parallel and hence the equations are equivalent.

Hence, option 4) is incorrect.

5)

Create a pair of lines that intersect at only one point.

if such a condition is true than the intersection point is the value of x and y.

hence we will get a unique value.

Hence, option 5) is true.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
