If (x, y) is a solution to the system of equations above, then what is the value of x - y? a. 1/4b. 1c. 3d. 18

1. The first step to solving this problem is to find the values of x and y. This can be done in a multitude of different ways, however I will go with the method of substitution.

Thus, the first thing we must do is write out both equations and rearrange one of them so that either x or y is the subject of the equation. Looking at the two equations, I can see that in the second equation this would be easier, and that we could also simplify the first equation a little further. Thus:

a) Collecting like terms to simplify equation 1:

4x + 3y = 14 - y

4x + 4y = 14 (Add y to both sides)

b) Rearranging equation 2 to make x the subject:

x - 5y = 2

x = 2 + 5y (Add 5y to both sides)

Now, we can substitute x = 2 + 5y into the first equation:

4x + 4y = 14

if x = 2 + 5y:

4(2 + 5y) + 4y = 14

8 + 20y + 4y = 14 (Expand 4(2 + 5y))

8 + 24y = 14 (Add 20y and 4y)

24y = 6 (Subtract 8 from both sides)

y = 1/4 (Divide both sides by 24)

Now that we know that y = 1/4, we can substitute this back into x = 2 + 5y:

x = 2 + 5y

if y = 1/4: x = 2 + 5(1/4)

x = 2 + 5/4

x = 13/4

2. So now we know that x = 13/4 and y = 1/4. Given these values, we can now solve x - y as such:

x - y = 13/4 - 1/4

= 12/4

= 3

Thus, the value of x - y is 3 (answer C).

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
