Answer:
343
Step-by-step explanation:
7x7x7 = 343
Equation 1) 3x + 3y = 12
Equation 2) x - 5y = 10
First step : 3(x - 5y = 10)
Well, we have to simplify this equation first. *Remember, this is the second equation.
Equation 1) 3x + 3y = 12
Equation 2) 3x - 14y = 30
Well, because both equation 1 & 2 have positive 3x in their equations, we must subtract the equations from one another in order to find the y value.
So, your answer is : C) Subtract the equations.

Answer:
A) g is increasing, and the graph of g is concave up.
Step-by-step explanation:
g'(x) = ∫₀ˣ e^(-t³) dt
Since e^(-t³) is always positive, ∫₀ˣ e^(-t³) dt is positive when x > 0. So the function is increasing.
Find g"(x) by taking the derivative using second fundamental theorem of calculus:
g"(x) = e^(-x³)
g"(x) is always positive, so the function is always concave up.
