Answer:
2750 x (1 - 0.21)ˣ
Step-by-step explanation:
Original: 2750
1st week after: 2750 x (1 - 0.21)
2nd weeks after: 2750 x (1 - 0.21) x (1 - 0.21) = 2750 x (1 - 0.21)²
x weeks after: 2750 x (1 - 0.21)ˣ
Answer:
The answer is A.
Step-by-step explanation:
You have to add up both polynomials together :
A = 7x² + 3xy
B = -3xy
A + B = 7x² + 3xy + (-3xy)
= 7x² + 3xy - 3xy
= 7x²
What do you want help with an equation or something else
Answer:
-19
Step-by-step explanation:
If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: <em>(-4) - (5 * 3).</em>
Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.
Now the expression is <em>(-4) - (15).</em> Then, you do the subtraction. -4 - 15 is equal to -19.
