Answer:
Both versions of the expression equal the exact same amount;one is just much shorter.Simplifying algebraic expressions is the same idea,except you have variables in your expression.So,Basically you're turning a long expression into something you can easily make sense of
D = {5; 7; 9; 11}
y = 45 - 3x
substitute the values of x from the domain to the equation:
for x = 5: y = 45 - 3 · 5 = 45 - 15 = 30for x = 7: y = 45 - 3 · 7 = 45 - 21 = 24for x = 9: y = 45 - 3 · 9 = 45 - 27 = 18for x = 11: y = 45 - 3 · 11 = 45 - 33 = 12
Answer: The range is { 12; 18; 24; 30}.
Answer:
315 divide by 7 nevermind
Step-by-step explanation:
Step-by-step explanation:
At d, f'(x) is increasing (concave up), but it is not positive. The tangent line at that point has a negative slope.
Answer:
91
Step-by-step explanation:
Because the equation is equal to 91
