Step-by-step explanation:
gegehehehjwjwjwjwwk
1. y = 2/3x - 5
2. 4x - 6y = 30
Divide 2. by 2
3. 2x - 3y = 15
Substitute 1. into 3.
4. 2x - 3(2/3x - 5) = 15
5. 2x - 2x + 15 = 15
6. 15 = 15
False. There are an infinite number of solutions.
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

Answer:
54 sq ft
Step-by-step explanation:
Area of a triangle is given by :
Area = (1/2) x base x height
in our case, if we assume the base of the right triangle to be 12 feet, then the height is 9 feet
Substituting this into our equation
Area = (1/2) x 12 x 9
Area = 54 sq ft
