The mean of the data set 1 is 3.6 because if you add all the numbers up you’ll get 32/9 = 3.555555556 or 3.6

The mean of the data set 2 is 9.3 because if you add all the numbers up, you’ll get 93/10=9.3

The slope of the line passing through(-2,5) and (4,-1) is:
Lady bird [3.3K]

Answer:

The slope of the line passing through (-2, 5) and (4,-1) is -1.

Step-by-step explanation:

To solve this equation, we can use the formula Δy÷Δx=s.

(Change in y divided by change in x is equal to slope)

First, plot the two points on a graph, then draw a line connecting the two points.

Then, draw a line from (-2,5) to (-2,-1). Since the line goes down by 6 units from (-2,5), this means that the change in y is -6.

Draw a line from (-2,5) to (4,5). Since the line goes right by 6 units from (-2,5), this means that the change in x is +6.

Δy÷Δx=s

-6÷6=s

-6÷6=-1

-1=s

Therefore, the slope of the line passing through (-2, 5) and (4,-1) is -1.

1.(8x+3)(4x-5) 2.(10x-2)(3x+6) please show your work will mark brainliest
ANEK [815]

Answer:

1)

32x^2 - 28x - 15

2)

30x^2 + 54x - 12

Step-by-step explanation:

1.

(8x+3)(4x-5)

Using FOIL

= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)

= 32x^2 - 40x + 12x - 15

= 32x^2 - 28x - 15

2.

(10x-2)(3x+6)

Using FOIL

= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)

= 30x^2 + 60x - 6x - 12

= 30x^2 + 54x - 12
