Evaluate the expression when x = -2/3 and y= 2/9 x-4y

Mathematics

Answer:

-14/9

Step-by-step explanation:

We can plug -2/3 in for x and 2/9 in for y:

-2/3-4(2/9)

-2/3-8/9

We need the fractions to have the same denominator so we can convert -2/3 into -6/9

-6/9-8/9

-14/9

Answer:

1 < x < 12

Step-by-step explanation:

The triangles satisfy the Converse Hi nge Theorem Condition the two triangles have two corresponding equal sides. Thus, the included angle of the triangle that has the largest length of the third side is greater than the included angle of the other triangle with a lesser third side length.

Thus,

33 > 3x - 3

Solve for x

33 + 3 > 3x - 3 + 3

36 > 3x

36/3 > 3x/3

12 > x

To ensure the angle is not 0 or negative, thus:

3x - 3 > 0

Solve for x

3x - 3 + 3 > 0 + 3

3x > 3

3x/3 > 3/3

x > 1

Possible range of values of x would be:

1 < x < 12
