Answer:
y = 1.5
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 48 when y = 6
k = = =
y = x ← equation of variation
When x = 12, then
y = × 12 = 1.5
Answer:
Step-by-step explanation:
we have
<em>The equation of the first line</em>
------> equation A
<em>The equation of the second line</em>
------> equation B
Solve the system of equations by elimination
Multiply equation A by -4 both sides
--------> equation C
Adds equation B and equation C
<em>Find the value of x</em>
substitute the value of y
Multiply by 3 both sides
therefore
The solution to the system of equations is the point
