Answer:
The explicit formula for the given expression is .
Step-by-step explanation:
The given sequence is
-7, -4, -1, 2, 5
The difference between two consecutive terms is same, therefore the given sequence is an arithmetic sequence.
The first term of the given AP is -7 and the common difference is
The explicit formula for an AP is
Where, a is first term, d is common difference and n is number of terms.
Substitute a=-7 and d=3 in the above equation.
Therefore the explicit formula for the given expression is .
Answer:
The answer is B
Step-by-step explanation:
Basicly, you have to plug in the x values from the table into the x value in the equation and solve for the asnwer. If the answer is similar to the answer shown in the table as y, then you know that the x value is correct.
Answer:
18 nickels, 9 dimes, and 6 quarters.
Step-by-step explanation:
Just use the guessing method. I started with 15 and then went to 18. and got it right. A nickel a worth five cents so 18 times 5 = 90 cents. 18/3 is 6 and 18+6=24. 24/2 is 12 and 12-3 is 9. A dime is worth 10 cents so 9 times 10= 90 cents. A quarter is worth 25 cents and 6 times 25=150. 150+90+90+330 If you get this right can i please have brainliest
D. (9x-4)^2
You can get this by taking the square roots of the outside terms. Then multiply them together and then by 2. For this you should get the middle term.
Answer:
2xy - 6x +2y
Step-by-step explanation:
12xy - 10xy = 2xy
5y - 3y = 2y
2xy - 6x + 2y
