Answer:

  (5x +0.7y^2)(5x -0.7y^2) = 25x^2 -0.49y^4

Step-by-step explanation:

We know the product of a sum and difference can be the difference of squares. The term on the far right is a perfect square: -(0.7y^2)^2.

The binomials on the left look like a sum and difference, so we can fill this in as ...

  (5x +<u>0.7y^2</u>)(5x -<u>0.7y^2</u>) = <u>25x^2</u> -0.49y^4

skelet666 [1.2K]

Answer:

58

Step-by-step explanation:

the mean is adding up all the numbers, then dividing by the amount of the numbers.

add up all the numbers:

13 + 13 + 14 + 18 + 22 = 80

the mean is 23.

so you need to back track:

23 * 6 = 138

138 - 80 = 58

M= 1 1/2 going through (6,4) plug into y=mx=+b
Tema [17]
M = 1.5 = 3/2
y = mx + b
b = y - mx = 4 - (3/2)6 = 4 - 9 = -5
So equation of the line is:
y = 3x/2 - 5
