Answer:
b = -2
Step-by-step explanation:
Take the cube root of both sides of the equation.
b^3 = (-2)^3
b = -2
_____
There are two other complex solutions. It isn't clear from the problem statement whether you are interested in those or not. They are 1±i√3. They can be found by factoring b^3+8 = 0 as (b+2)(b^2 -2b +4) = 0. They are the roots of the quadratic.
Answer: y = 2/3 x + 3
Step-by-step explanation:
You are supposed to find y = mx + b.
In that equation y = mx + b, b is the y intercept or the dot that passes through the y axis. The m in the equation is the slope, to find the slope you find the rise over run the simplify it as much as you can.
2 add them all together and divide by 6 and you get 4.007
Answer:
x = 9/2
Step-by-step explanation:
Solve for x:
4 (5 - 8 x) = -24 x - 16
Expand out terms of the left hand side:
20 - 32 x = -24 x - 16
Add 24 x to both sides:
24 x - 32 x + 20 = (24 x - 24 x) - 16
24 x - 24 x = 0:
24 x - 32 x + 20 = -16
24 x - 32 x = -8 x:
-8 x + 20 = -16
Subtract 20 from both sides:
(20 - 20) - 8 x = -20 - 16
20 - 20 = 0:
-8 x = -20 - 16
-20 - 16 = -36:
-8 x = -36
Divide both sides of -8 x = -36 by -8:
(-8 x)/(-8) = (-36)/(-8)
(-8)/(-8) = 1:
x = (-36)/(-8)
The gcd of -36 and -8 is -4, so (-36)/(-8) = (-4×9)/(-4×2) = (-4)/(-4)×9/2 = 9/2:
Answer: x = 9/2
Answer:
x=6.75
