<span>-7(7m-4)=77
Use distributive property(Multiply -7 by 7m and -4)
-49m + 28= 77
Subtract 28 from both sides
-49m= 49
Divide -49 on both sides so that the only thing remaining on the left side is the variable m.
Final Answer: m = -1</span>
Answer:
SP = selling price
SP = [(100 + Gain%) / 100] * CP.
SP = [(100 – Loss %) / 100]*CP.
Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it.
Answer:
Step-by-step explanation:
For equating the equations, you get
x2 + kx - 3x + 4 = 0 eq1
Setting the derivative of f(x) equal to 3 yields
f'(x) = 3
2x + k = 3 eq2
Now we substitute the value of k from eq2 into eq1.
x2 + x(3 - 2x) - 3x + 4 = 0
Solve for x from this equation. Then plug in the value of x into eq2 to solve for k
