Answer:

<u>AP equation:</u>

  • t_n=t_1+(n-1)d

<u>Based on the first two terms, we have:</u>

  • t_1=3,\\t_2=9\\d=9-3=6

<u>The equation is:</u>

  • t_n=3+(n-1)*6=3+6n-6=6n-3

<u>Next two terms are:</u>

  • t_3=6*3-3=15\\t_4=6*4-3=21

PLS HELP! which graph is the function 3x + 2y = 8 with the given domain {-2,0,2,4}??
Romashka [77]

Answer:

D

Step-by-step explanation:

Domain of the function 3x + 2y = 8 are the possible set of x-values represented as {-2, 0, 2, 4}.

To know which graph represents the above given function, find the range values of the function by plugging in each value of x into the equation, to find y.

For x = -2,

3(-2) + 2y = 8

-6 + 2y = 8

2y = 8 + 6

2y = 14

y = 14/2

y = 7

(-2, 7)

For x = 0,

3(0) + 2y = 8

0 + 2y = 8

2y = 8

y = 8/2

y = 4

(0, 4)

For x = 2,

3(2) + 2y = 8

6 + 2y = 8

2y = 8 - 6

2y = 2

y = 2/2

y = 1

(2, 1)

For x = 4,

3(4) + 2y = 8

12 + 2y = 8

2y = 8 - 12

2y = -4

y = -4/2

y = -2

(4, -2)

The graph which shows the following set of coordinates pairs calculated above, ((-2, 7), (0, 4), (2, 1), (4, -2)), is the graph of the function 3x + 2y = 8.

Thus, the graph in option D the shows the following calculated coordinate pairs. Therefore, graph D is the answer.

TiliK225 [7]

Answer:

100

Step-by-step explanation:

4\times(2+3)^{2}

This can be turned into:

4\times5^{2}  (if we add the numbers inside the brackets)

Following PEDMAS, this becomes:

4\times25 which equals 100

∴  4\times(2+3)^{2}=100
