Which function represents the sequence?

Tom [10]

Answer: SECOND OPTION

Step-by-step explanation:

Substitute any value of n shown in the table attached into each function given in the options, and observe if you obtain the value of $a_n$ shown in the table.

Let's substitute n=1 (According to the table, you need to obtain $a_n=3$ ):

For the first option:

$f(1)=1+3=4$

For the second option:

$f(1)=7(1)-4=3$ THIS IS THE FUNCTION

For the third option:

$f(1)=3(1)+7=10$

For the fourth option:

$f(1)=1+7=8$

Therefore, the answer is the second option.

Need help with this problem:

Nitella [24]

Answer:

Henson: 3x + y = 163

Garcia: 2x + 3y = 174

adult ticket price: $45

child ticket price: $28

Step-by-step explanation:

Henson Family:

3 adults + 1 child; total $163

3x + y = 163

Garcia Family:

2 adults + 3 children; total $174

2x + 3y = 174

Now we solve the system of equations.

Solve the first equation (Henson Family) for y.

y = 163 - 3x

Substitute 163 - 3x for y in the second equation (Garcia Family).

2x + 3y = 174

2x + 3(163 - 3x) = 174

2x + 489 - 9x = 174

-7x + 489 = 174

-7x = -315

x = 45

Now substitute 45 for x in the first original equation and solve for y.

3x + y = 163

3(45) + y = 163

135 + y = 163

y = 28

adult ticket price: $45

child ticket price: $28

Alan and his classmates performed a linear regression analysis on the data set shown below and found that the line of best fit t

stealth61 [152]

Answer:

C. $y=\frac{4}{5}x+7$

Step-by-step explanation:

Alan and his classmates found that the line of best fit through the data had the equation $y=-\frac{5}{4}x+18$

The slope of this line is $m=-\frac{5}{4}$

If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.

The slopes of perpendicular lines are negative reciprocals of each other,

Hence that line must have slope $\frac{-1}{-\frac{5}{4}} =\frac{4}{5}$

Therefore we look for a line whose slope is $\frac{4}{5}$ from the given options.

That line is the third option $y=\frac{4}{5}x+7$
