Answer: (3,5)
Step-by-step explanation:
y=3x-4
2x-3y=-9
2x-3(3x-4)=-9
2x-9x+12=-9
7x=21
x=3
y=3(3)-4
y=5
Answer: x = 0
Step-by-step explanation: To solve for <em>x</em> in this equation, our first step is to simplify the left side by distributing the 10 through both terms inside the parentheses.
When we do that, we get 10 times x which is 10x
and 10 times -2 which is -20.
So we have 10x - 20 = -20.
Adding 20 to both sides, we get 10x = 0.
Divide both sides by 10 and <em>x = 0</em>.

For this case we have an inverse variation equation given by two variables, x and y respectively. This equation is represented by: , we must find the value of the variation constant "k" whenand . Then, we must substitute the values of "x" and "y" given in the inverse variation equation and find the constant "k":
Thus, the value of the constant of variation "k" is 10.
Answer:
Option D
Answer:
Fractional form of 2.5 is 5/2.
5.4 as a fraction is 27/5.
Answer:
Area = 19.05 feet squared
Step-by-step explanation:
By applying sine rule in ΔABC,
sin(∠CAB) =
sin(60°) =
BC = 2√3
Area of a parallelogram is given by the formula,
Area = Base × Height
= 5.5 × 2√3
= 11√3
= 19.05 ft²
Therefore, answer is Area = 19.05 ft squared.
