Find the value of y (super easy)

Mathematics
1 answer:
Talja [164]3 years ago
5 0

Answer:

Step-by-step explanation:

4x + 23 + 9x - 38 = 180

13x - 15 = 180

13x = 195

x = 15

4(15) + 23= 60 + 23= 83

9(15) - 38 = 135 - 38= 97

21y - 1 + 97 = 180

21y + 96 = 180

21y = 84

y = 4

21(4) - 1 = 84 - 1 = 83

here are the first four tearms of a sequence 1, 11, 22, 37, find and express in terms of n the nth term of this sequence
Umnica [9.8K]

2n² + n + 1

<u>Explanation:</u>

The sequence is 4, 11, 22, 37

Difference between:  7, 11, 15

The first differences are 7, 11, 15, and the second differences are 4.

Since half of 4 is 2, then the first term will be 2n^2.

Subtracting 2n² from the sequence gives 2, 3, 4, 5 which has nth term n + 1.

Therefore the final answer is 2n² + n + 1

Which one does it simplify to? please
9966 [12]

Answer:

1    +    { \sin}  \theta

Step-by-step explanation:

\frac{  { \cos}^{2}  \theta}{1 -  \sin \theta}  \\  \\  = \frac{  { \cos}^{2}  \theta}{(1 -  \sin \theta)}  \times  \frac{(1  +  \sin \theta)}{(1  +   \sin \theta)}   \\  \\  = \frac{{ \cos}^{2}  \theta(1    +    { \sin}  \theta)}{(1   -   { \sin}^{2}  \theta)}  \\  \\  = \frac{{ \cancel{ \cos}^{2}  \theta}(1    +    { \sin}  \theta)}{ \cancel{{ \cos}^{2}  \theta}}   \\  \\  = 1    +    { \sin}  \theta

Answer:

  • f(x) = x² -3
  • g(x) = 6x +7
  • h(x) = 3^x

Step-by-step explanation:

f(x) is copied from the problem statement.

g(x) is a symbolic representation of the English wording, using x to represent "a number."

h(x) is the exponential function that corresponds to the geometric sequence in the table. It has a common ratio of 3, and a multiplier of 1 at x=0.
