15000 because 15kg x 1000 = 15000g
First let's find the slope
Slope formula:

Given the two coordinates:
(-4,-7) (3,2)
x1,y1 x2,y2
Plug these numbers into the formula

In this case the mistake that was made was that the student wrote the slope negative instead of positive
Final answer:
<span>y-2=9/7(x-3)</span>
Answer:
S = 9.9
Step-by-step explanation:
First, multiply by -3 to remove fractions:
so:
S - 38.4 = -28.5
Take all values to one side by adding 38.4 to both sides
S = 9.9
Well use photo math that will give u the answer and how to work it out
4 outcomes,
Heads - Heads
Heads - Tails
Tails - Tails
Tails - Heads
With every coin added the amount of outcomes is multiplied by two
