Answer:

B. f(-1)=6

C. The domain of f(x) is the set {-2.-1,0,1,2,3,4,5,6}

Step-by-step explanation:

To find f(5) from the table means, the y-value that corresponds to x=5.

This value is 12.

This implies that:

f(5)=12

Also the y-value that corresponds to -1 is 6.

Hence f(-1)=6

The domain of f(x) are the set of all the x-values.

The domain is : {-2.-1,0,1,2,3,4,5,6}

The range for f(x) is the set of all the corresponding y-values.

From the table, the range is: {5,6,7,8,9,10,11,12,13}

Kyle notices that the number of likes he receives each day on his social media page is a function. He decides to create a graph

nadya68 [22]

Answer:

D) 360

Step-by-step explanation:

The data Kyle collected is (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.

We can write a linear function to model this situation.

This will be of the form

$y = mx$

because it passes through the origin , where m is the slope.

The slope is

$m = \frac{12 - 0}{1 - 0} = 12$

Hence the equation is

$y = 12x$

To find the number of likes on the 30th day, we put x=30 into the equation to get:

$y = 12 \times 30 = 360$

The correct choice is D

In the figure below, Find AB Help

Tema [17]

we have:

CD ÷ CA = DE ÷ AB

=> 6 ÷ 11 = 12 ÷ AB

=> AB = 12 × 6 ÷ 11 = 72/11 ≈ 6,5

Answer: 72/11 ≈ 6,5

P/s: CA = CD + AD = 6 + 5 = 11

Ok done. Thank to me :>

2 divided by 1 and 6/7

ale4655 [162]

This problem, as written, requires a bit of guessing regarding your intentions. My interpretation is that you want to do this division:

----------

1 6/7

If that's correct, here's what to do: rewrite 1 6/7 as 13/7 (an improper fraction).

Then divide:

-------- This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)

13/7
