Solve 2x^2=11x+6 by factoring

Answers

Answer 1
Answer:

Answer:

(x-6) (2x+1)

Step-by-step explanation:

1) move everything over to the left side, so subtract 11x and 6.

2x^2 -11x - 6 = 0

2)multiply 2(a term) with -6 (c term)

x^2 -11x -12

3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1

(x-12) (x+1)

4) divide -12 and 1 by the original a term (2)

(x-6) (x+1/2)

5) move the denominator of 2 over to the x.

(x-6) (2x+1)

Which of these percentages is closest in value to 7/9 ?
a. 76%
b. 77%
c. 78%
d. 79%

Answers

(7)/(9) = 0.777777777777777...

To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.

0.78*100 = 78

This shows your answer is (c) 78%.
(7)/(9)  0.77777..

0.7777 ≈ 0.78

0.78*100=78          \boxed{->C}

The answer is 78%

Find the 40th term of this arithmetic sequence.

Answers

199 is the answer because the equation you use is an=a1+d(n-1). Where an (the n is actually supposed to be smaller than the a) is the nth term (a40), a1 (1 smaller than a) is the first term (4), d is the difference (5), and n is the number of the term you're looking for (40)
