Can someone help me with this, im not really good at math and i dont understand this :(

cluponka [151]

Answer:

y = 2x + 4

Step-by-step explanation:

First find 2 points on the line to determine slope.

(0, 4) and (2, 8)

Slope = $\frac{8-4}{2-0}=2$

y = 2x + b

b = y - intercept

b = 4

y = 2x + 4

The mean of the data set is 15.What number is missing? 9,12,16,18,23

maxonik [38]

The number 12 is missing in the data set.

<u>Step-by-step explanation</u>:

The numbers are 9,12,16,18,23.
The missing number is assumed to be 'x'

Mean = Sum of the integers / Total number of integers.

15 = (9+12+16+18+23+x) / 6

15 = (78+x) / 6

90 = 78+x

x = 90-78

x = 12

What are the types of roots of the equation below?<br><br>x^4 - 81 = 0

natali 33 [55]

Answer:

x^4 - 81 = 0

(x² - 9)(x² + 9) = 0

Notice that the first of these is itself a difference of two squares:

(x - 3)(x + 3)(x² + 9) = 0

So the solutions are x = 3, x = -3, x = 3i, x = -3i
