F(x) = x² - 1
f(2a) = 35
f(2a) = (2a)² - 1 = 35
4a² - 1 = 35
4a² = 35 + 1
4a² = 36
a² = 36/4
a² = 9
a = √9
a = +3 or -3.
Divide by 2 on each side: x+2y=10
If y is 0, x=10. If x=0, y=5.
x-intercept: (10, 0)
y-intercept: (0, 5)
Draw those two points, connect, and extend.
To find the answer, just divide 77 by 6. This gets you 12.83. (simplified) 12.83 is also your answer. I hope this helps!
