Answer:
x = -4
Step-by-step explanation:
3(2x+8)=0
Divide each side by 3
3/3(2x+8)=0/3
2x+8 = 0
Subtract 8 from each side
2x+8-8=0-8
2x = -8
Divide by 2
2x/2 = -8/2
x = -4
To solve the problem we must establish two equations.
let x be the mass of the 20 cents almonds
y be the mass of the 36 cents mixture
first equation is:
x + 40 = y
the second equation is:
0.2x + 40(0.4) = 0.36y
solving the equations simultaneously
x = 10 lb of the 20 cents almonds is needed to mix

Slope :
--------------------------------------------------------------
Slope = 2 (negative reciprocal of the perpendicular line)

Y-intercept :
--------------------------------------------------------------
at (1, 5)
5 = 2(1) + b
5 = 2 + b
b = 3

Equation : y = 2x + 3
--------------------------------------------------------------
I think the answer is either b or c i am not sure
