x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8

Which equation represents the graph of the linear function?
Answers
The line on that graph is sloping down as it proceeds from
left to right, it drops 3 units for every 1 unit to the right, and
it crosses the y-axis at y=1 .
So the equation of that line is y = -3x + 1 .

Step-by-step explanation:
2x⁴ = 9x²
2x⁴ - 9x² = 0
x²(2x² - 9) = 0
Either x² = 0 or 2x² - 9 = 0.
When x² = 0, x = 0.
When 2x² - 9 = 0, x² = 9/2, x = ± 3/√2.
Hence the solutions are
x = 0, x = 3/√2 and x = -3/√2.

Answer: v = 16
Step-by-step explanation:
A slope of ten means that for every +1 increase in the x-coordinate, the y-coordinate increases by +10. Using this information, we can solve for v.
We will add one to the x-value and add 10 to the y-value.
Given:
(7, 6), m = 10
Use the slope:
(7 + 1, 6 + 10) = (8, 16)
Answer:
v = 16
