Answer: The systems are solved by solving for one variable in one of the equations, then substituting that equation into the second equation. Solve for a in the second equation, then substitute the second equation into the first. The Elimination Method: Both equations are in standard form: Ax + By = C.
Answer:
20
Step-by-step explanation:
Step 1: find the derivative of y = x^2 + 12x - 7; it is 2x + 12.
This function represents the slope of the tangent line to the given curve at x.
Step 2: Substitute 4 for x in f '(x) = 2x + 12: f '(4) = 2(4) + 12 = 20
The slope of the tangent line to the graph of y = x^2 + 12x - 7 at x = 4 is 20.
Answer:
9
Step-by-step explanation:
I just did this is class the answer is 23=p.250 then do p.250 over 250 cross that the do 23 over 250 so divide 23 by 250 you will get 0.092 move the decimal point two times over you will get 9.2 round that up to the nearest whole number and you will get 9 so 9 percent :)
