6x + 5y = 7
-6x - 9y = -9
-4y = -2
y = 1/2 or 0.5
2x + 3(1/2) = 3
2x + 1.5 = 3
2x = 1.5
x = 0.75
288m^3 is what I got, hope it helps!
Step-by-step explanation:
step 1. what is the question? probably solve for x. okay.
step 2. 4^(2x) + 1 = 4
step 3. 4^(2x) = 3 subtract 1 from each side
step 4. ln4^(2x) = ln3 take on of each side
step 5. 2xln4 = ln3 definition of logs
step 6. 2x = ln3/ln4 divide both sides by ln4
step 7. x = ln3/2ln2^2 divide both side by 2 and replace 4 with 2^2
step 8. x = ln3/4ln2.

Sorry I can't graph it for you but here are the equations in the slope-intercept form
11)y=-2/3x+8
12)y=-8/9x-16
13)y=-5/3x+10
