Answer: x=7
Step-by-step explanation: First you distribute the 12 to (10-x). That then gives you 15x+120-12x=141. Now you combine like terms. So you do 15x-12x=3x. Your new equation now is 3x+120=141. Subtract 120 from 141 and mark it out. That leaves you with 3x=21. Divide both sides by 3. Your final answer is x=7.

Answer:
{x,y,z} = {1,-1,-2}
Step-by-step explanation:
First, find the x-intercept of g(x) = x³ - 1. x³ = 1, so x = 1. The x-intercept is (1,0).
We must now find the equation of the tangent line to the graph at (1,0):
slope of tangent line = 3x^2 with x = 1, or m = 3(1)^2 = 3.
Last, find the equation of the line with slope 3 that passes through (1,0):
0 = 3(1) + b. Then b = -3, and the equation of the tangent line at (1,0) is
y = 3x - 3.
Make a proportion
81/30 = x/600
600/30 = 20
x/81 = 20
x = 1620
Solution: 1620 calories
